BlackArmor Data Recovery Part 2

Note: This is a continuation of my previous post

Since I don’t really have the time to play around with installing Debian on the BA440 I’ve decided to add the missing drive back in to the RAiD5 array and use my Debian box with the drives attached in the USB docking ports as an iSCSI endpoint. Not exactly a tidy desktop solution but this will go in the server room. If I get some spare time I will look at replacing the firmware on the BA. If I do, I’ll be sure to write about it.

To add my missing drive, the one the BA “recover” process messed up , I first have to identify it.

# cat /proc/partitions

You should see your system partitions probably /dev/sd[abc…] all 3 of your /dev/sd[bcde] paritions (one of the [bcde] will be the missing drive so it won’t be listed, and then a root partition for the new drive.

The missing or new drive will show up as /dev/sdf

If it’s new all that will be there is /dev/sdf and you can skip this next step.

Lots of partition tutorials will tell you to use fdisk and/or cfdisk for partition work but these won’t work with the GPT format of the BA, we need to use parted. GPT is a newer partition format used for large disk partitions and parted is the tool built to manage them.

The aborted BA recovery process tried to create partitions that weren’t correct (partition sizes did not match the others in the array) so I had to delete the partitions.

IMPORTANT: This destroys any data on the disk so make sure you’ve got the correct disk reference.

To do this run

# parted /sdf
<parted> rm 1
<parted> rm 2
<parted> rm 3
<parted> quit

rm removes the partitions. If you rerun cat /proc/partitions you will now see just /dev/sdf.

Next we need to get the exact details of the setup of the disks in the array so we run parted on a member of the array. It doesn’t matter which one as they are all the same structure.

# parted /sdd
<parted> print

Number    Start     End     Size   File system      Name       Flags
1         100MB     1169MB  1069MB ext3                        raid
2         1169MB    2239MB  1070MB linux-swap                  raid
3         2239MB    2773MB  534MB  ext3                        raid
4         2773MB    1000GB  997GB                   primary    raid
<parted> quit

Copy this output down or print it out. Important: Make sure you quit parted otherwise the next steps you make will be on the good disk in the array. You don’t want that.

Now go back and use parted on the new drive /dev/sdf

While in parted we’ll use mkpart [part-type fs-type name] start end.

For the first 3 partitions we’ll define the part-type which is either ext3 or linux-swap. For the last we’ll assign the fs-name which is “primary”. We do not define a part-type for our 4th partition which will become our data partition.

# parted /sdf
<parted> mkpart ext3 100MB 1069MB
<parted> mkpart linux-swap 1169MB 2239MB
<parted> mkpart ext3 2239MB 2773MB
<parted> mkpart primary 2773MB 1000GB
<parted> quit

If you rerun cat /proc/partitions you will see that /dev/sdf now has 4 partitions


Now all we need to do is add /dev/sdf4 to our array. To do this we go back to mdadm. From the last post we remember that /dev/md3 is our raid array.

mdadm --manage /dev/md3 --add /dev/sdf4

The  disk is now added to the array. You can check its status by running

mdadm --detail /dev/md3

Raid Level: Raid5
Raid Devices: 4
Total Devices: 4
State: clean, degraded, recovering
Active devices: 3
Working devices: 4
Failed devices: 0
Spare devices: 1
Rebuild status 3% complete
Raid Device
0 active sync /dev/sdb4
2 active sync /dev/sdd4
4 spare rebuilding sync /dev/sdf4
3 active sync /dev/sde4

I’ve edited the output to just the relevant bits. You can see the array is rebuilding. This can take a long time depending on the size of the drives. In the time it took to write this the array has only moved from 3% to 4% complete. This is normal and in 8 -10 hours or so, we’ll have a rebuilt 4 disk RAID5 array.

Once that is complete, I’ll look at setting up some new iSCSI mount points and moving it into the server room.

How To: Seagate BlackArmor Data Recovery after DataVolume Failed Error

The Seagate BlackArmor 440 is a RAID Capable SMB NAS. Mine consisted of 4 1 TB Seagate drives in a RAID5 array. I highly DON’T recommend it. Check out the posts in the Seagate Community Forums for “Data Volume Usage Failed status”. This error message is what led me from irritation, to denial, to despair, to confusion and finally to triumph. The tl;dr version is that one day for no apparent reason, your RAID5 array with all your data on it will simply show up as FAILED in the BA440 even if all the disks show no problem. Something in the BA440 RAID software has crapped out and the whole point of RAID is now out the window.

Update: I found this quote on the BA’s Amazon review page. “Contacted support and they said “RAID 5 config stores all parity information on drive 1” So yes if you have an issue with Drive 1, your array is useless.

As those of you who use RAID5 know, we are supposed to be able to withstand a complete failure of 1 disk and still have complete data integrity. This is why I bought the BA440. It was used as a data warehouse for old files, especially media files. 95G of media files, 7G of old (but still required) accounting data, 5G of required regulatory documents. All of it was inaccessible. It’s important to note here that not a SINGLE disk showed to have failed. A failed disk would have been (theoretically) easy to fix. This was not that. In other words, this was a huge disaster. I completely agree with the review author’s comment “I have worked in IT for 15 years and I have never come across something quite so stupid.”

If you search the Seagate forums you will find 5 basic solutions.

  1. Upgrade the firmware. If you’re lucky, your array will be working after a reboot.
  2. Restore from a backup. As several forum posts mention, a RAID5 NAS is –used- as a backup in many, many instances, probably the majority of them. And no I did not have a backup of my backup.
  3. Send your drives to Seagate Data Recovery Services where they will be happy to recover the data for you for $3,000 to $20,000 (plus s&h). Uh, no thanks.
  4. Remove the drives, attach them to a windows system and use one of the several NAS recovery software tools. I tried the following.
      • NAS Data Recovery – Runtime Software
      • ReclaiMe Raid Recovery/FileRecovery –
      • UFS Explorer RAID recovery – SysDev Labs

    Of these, the only one that I tried that seemed to work at all was the UFS Explorer. After a 20 hour scan, I was able to view the file structure and see that it would likely be able to recover many files. The trial version only allows viewing/copying of small files. The full version (155 Euros) unlocks larger files. I was able to open some PDFs and small word docs but can’t verify that it would have worked for all files.  Had I just had the basic BA440 setup, I probably would have paid for the full version of UFS and been able to recover most if not all of my data. There was a problem though. The 95G of media files were on an iSCSI drive hosted on the BA440. Using iSCSI allowed me to have a mapped drive letter pointed directly to the BA440 rather than having to deal with a cumbersome webinterface. It also sped up file transfer (which was atrocious even sped up…another reason to avoid the BA series). UFS had no idea what to do with that iSCSI data and couldn’t even see it.

  5. Get your linux-fu going and try to recover the data yourself.

This post is about how to mount your RAID5 array in Debian, create an iSCSI target so that Windows 7 can see it and get all of your data back like a superstar.

From here on this is a AS AT YOUR OWN RISK kind of tutorial. Nothing that follows should damage your data but I’m not a linux genius and you might not be either so you might want to image those disks before proceeding. Search for Clone RAID disk for details on how to do that. FWIW, I didn’t. ALSO, when you following along and the output of your system isn’t what I’m saying it should, I’m not sure I can help. You can ask but as noted, I’m not a linux expert. I’ll also note that what follows is a compilation of bits and pieces for 2 or 3 dozen various linux related websites. One of the frustrating things I found is that most of the sites had steps but didn’t really explain them (so a windows guy could understand at least) I hope that this post avoids that.

No matter if you are using method 4 or 5, the first hurdle is to get your disks attached to a machine so you can access the disks outside the BA enclosure. Remove each disk. Most tutorials will say label it, but I’m not sure it matters as 1) I won’t be using the BA again and 2) I don’t think it’s possible to repair the array without a reformat so the disk order is irrelevant. But labeling takes a second so you might as well.  I was fortunate to have 4 unused eSATA USB docks in the server room. If you don’t have any kicking around, they’re between $50-70 for a dual dock (so $100-ish total for 4 disks). You could also use eSATA cables to you motherboard if you have enough spares or buy an eSATA PCI expansion card. (also about $100 for 4 ports)

Now here, I should note I’m a windows guy and have only been playing with Linux for about 8 months. The command line doesn’t scare me though as I’m old enough to be a DOS guy too. I did happen to have a 10 year old Dell system that I had just installed Debian 7 (wheezy) on to use as a Radius Authentication Server. You can try using a live CD of various *nix distros but I had to install some packages and not sure how well that would work. The other draw back of a Live CD is that if you need to reboot or you lose power you need to re-do everything as nothing is saved. Everybody has a crappy old system stuffed in a closet, get it out & breathe new life into it.

At this point we’ll assume you have Debian 7 running and your 4 drives hooked up via USB. To keep this focused I’m going to assume you have at least –some- linux experience. You don’t need a lot but familiarity with the terminal console and basic how-to-get-things-done is required.

Open a terminal as root. This prevents you from having to sudo every command.

We need to install mdadm (Multi Disk array ADMin)

root@radiusserver: apt-get install mdadm

and the iSCSi target package and associated files

root@radiusserver: apt-get install iscsitarget
root@radiusserver: apt-get install iscsitarget-dkms

Note that the dkms package can take quite a while to install.

Some of the steps require us to make some configuration file edits. You can us vi or nano which are the nix geek method but I prefer a GUI so I use gedit. If you don’t have it you can

root@radiusserver: Apt-get install gedit

Once everything is installed we need to make sure the system can see the RAID drives.

root@radiusserver: cat /proc/mdstat

The output is as follows

Personalities : [raid1]
md3 : inactive sdd4[1](S) sde4[3](S) sdb4[0](S)
2921867757 blocks super 1.2

md2 : active (auto-read-only) raid1 sdb3[0] sde3[3] sdc3[2] sdd3[1]
521408 blocks [4/4] [UUUU]

md1 : active (auto-read-only) raid1 sdb2[0] sde2[3] sdc2[2] sdd2[1]
1044800 blocks [4/4] [UUUU]

md0 : active (auto-read-only) raid1 sdb1[0] sde1[3] sdc1[2] sdd1[1]
1043840 blocks [4/4] [UUUU]

unused devices: &amp;lt;none&amp;gt;

You’ll note that md3 is shown as inactive. These are my 4 RAID drives.

Next we’ll look to see what mdadm can find out about these disks:

root@radiusserver: mdadm --examine /dev/sd[adbe]4

This checks all devices in /dev/sd so /dev/sda4, /dev/sdb4, etc.

It finds the following arrays

Array State : AA.A ('A' == active, '.' == missing)

There’s a couple of things to note here.

  1. Array State : AA.A (‘A’ == active, ‘.’ == missing) – mdadm sees that disk 3 of the array is missing, which as noted above, it is.
  2. Array UUID : 2dba9164:94ded8f1:1efe9130:56bae5be
  3. There are 3 devices found, all 1 TB drives
    • /dev/sdb4
    • /dev/sdd4
    • /dev/sde4

    That’s because I followed Seagate’s data recovery advice and tried to reclaim a disk which made it unusable to my RAID array. Fortunately, unlike the BA440, Linux knows how to rebuild a RAID5 array with one of the 4 disks missing.

  4. State : clean This means that there’s nothing wrong with the array and a good chance we’ll be able to get all the data back.

The rest of the output we can ignore.

Now we have a look at the status of the RAID array

root@radiusserver: cat /proc/mdstat

Personalities : [raid1]
md3 : inactive sdd4[1](S) sde4[3](S) sdb4[0](S)
2921867757 blocks super 1.2

md1 : active (auto-read-only) raid1 sdb2[0] sde2[3] sdc2[2] sdd2[1]
1044800 blocks [4/4] [UUUU]

md3 is our unmounted RAID. You’ll note the devices from mdstat and mdadm –examine commands are the same.

At this point we need to install another package LVM2 (Local Volume Manager) This allows us to read the format of the RAID array that the BA440 uses.

root@radiusserver: apt-get install lvm2

Next thing we need to do is assemble the disk back into an array we can mount and use. We use mdadm and specify the device (from mdstat) and uuid (from mdadm –examine) of the array.

root@radiusserver: mdadm --assemble --force /dev/md3 --uuid=2dba9164:94ded8f1:1efe9130:56bae5be

(note there may be no output here. There should be. See below)

The next 2 commands activate the Volume Group

root@radiusserver: modprobe dm-mod
root@radiusserver: vgchange -ay
No volume groups found

Oops. You may find this error appears after the vgchange command. This means that the OS has control over our device (as happens when you add a USB device like our docking stations). We need to stop the device so we can apply the setting we want. Since /dev/md3 is the device we want to use:

root@radiusserver: mdadm -S /dev/md3
mdadm: stopped /dev/md3

Now if we rerun the –assemble command

root@radiusserver: mdadm --assemble --force /dev/md3 --uuid=2dba9164:94ded8f1:1efe9130:56bae5be

We see the following output:

mdadm: /dev/md3 has been started with 3 drives (out of 4).

Of course since this is -real- RAID5, a missing disk is no big deal.

Now rerun

root@radiusserver: modprobe dm-mod
root@radiusserver: vgchange -ay

We see

1 logical volume(s) in volume group 'vg0' now active

Now we run lvscan to make sure we can see the new LV status

root@radiusserver: lvscan
ACTIVE            '/dev/vg0/lv0' [2.72 TiB] inherit

Now we need to create a Mount Point (basically a directory pointer)

root@radiusserver: mkdir /media/DATAVOLUME

Now we actually mount the volume so we can use it.

root@radiusserver: mount /dev/vg0/lv0 /media/DATAVOLUME

Note: If you get an error when when trying to mount the volume (/dev/lg*/lv* does not exist), you may be running into a block size issue. This is a known issue when running a Live OS version of Debian 7.6 from a USB stick. The Ext4 file system on the BA has a block size of 65536 and the Live OS can only read a block size of 4096. The solution is to run

apt-get install fuseext2

Note #2: Please see the comment from Vlad about using fusext2 in this situation. You may encounter issues when reading large files, such as the iSCSI target LUN. Again this only seems to apply if you are using the Live OS. I did not encounter any issues from the full install.

Then run

fuseext2 -o ro -o sync_read /dev/mapper/vg*-lv* /mnt

(where * is the appropriate volume id)

This seems to be a limitation of the Live OS and not a standard install but since many will try this from a Live OS (especially Windows users), it’s important to know this potential issue.

Thanks to Keaton Forest in the comments for this workaround.
Now list the contents of the mounted directory

root@radiusserver: ls /media/DATAVOLUME

And you should see a list of files on the DATAVOLUME of the RAID array.

aquota.user  iscsi_device  jewab     Public        webserverBackup
Download     IT_Archives   PDFArchives     __raclient  wiki

Now if you start up the Nautilus file browser

root@radiusserver: gksudo Nautilus

and you should be able to browse the “normal” non iSCSI files on the just mounted volume. Copy them to a network drive or local drive other that the RAID array. If you didn’t use iSCSI, you data recovery is complete. Time for a beer.

If you did have iSCSI set up on the BB440, you’ve got more work to do.

First, if you try to access the directory iscsi_device, you will receive a permission denied error. This directory contains the actual iSCSI target (or targets if you have more than one) so we need to take ownership of the directory by running:

root@radiusserver:/etc/iscsi# chown -R <your username> /media/DATAVOLUME/iscsi_device

Now list the contents of that directory

root@radiusserver: ls /media/DATAVOLUME

In my case is have 2 iSCSI targets

iSCSI-1 SQLBackup

I’m only going to recover the data from iSCSI-1 so that’s what I’ll focus on from now on. If you need to recover multiple devices, you would just repeat these steps

Now run

root@radiusserver: sudo gedit /etc/default/iscsitarget

This is likely empty. Add the following line to make enable the system to create an iSCSI target:


Next edit the iSCSI target configuration file

root@radiusserver: sudo gedit /etc/iet/ietd.conf

Don’t modify anything except add the following to the bottom of the file

Target iqn.2014-03.local.mynet:storage.Lun0
       Lun 0 path=/media/DATAVOLUME/iscsi_device/iSCSI-1,TYPE=fileio

This defines the Target name which is the iqn line. This is what will show up in the Discovered Targets window of the iSCSI Initiator in Windows. The second line defines the LUN (Logical Unit Number), giving it a number (0), the full path to the directory (remember that the path is CaseSensitive! That messed me up for a while) and specifies the type (fileio). FileIO is used for directories, there other types but we don’t need them.

Note: If you want to set up a second or more Target you would change the target id, Lun and path

Target iqn.2014-03.local.mynet:storage.Lun1
       Lun 1 path=/media/DATAVOLUME/iscsi_device/SQLBackup,TYPE=fileio

Now we need to allow connections to the target

root@radiusserver: sudo gedit /etc/initiators.allow

and add the following to the bottom of the file (it may be empty) iqn.2014-03.local.mynet:storage.Lun0

Now all we need to do is restart the iSCSI service:

root@radiusserver:/etc/iscsi# sudo service iscsitarget restart
[ ok ] Removing iSCSI enterprise target devices: :.
[ ok ] Stopping iSCSI enterprise target service: :.
[ ok ] Removing iSCSI enterprise target modules: :.
[ ok ] Starting iSCSI enterprise target service:.
. ok

Now we can check to make sure the target is running and available

root@radiusserver:/etc/iscsi# iscsiadm -m discovery -t st -p

(change the ip above to your local ip address)

Then we see our target,1 iqn.2014-03.local.mynet:storage.Lun0

Note here. If your Debian system has a firewall set up (iptables) you will need to allow access for port 3260. If you’ve set this up for recovery, the default Debian install does NOT use a firewall so you shouldn’t need to do anything.

Now all we need to do is head back to our windows machine and fire up the iSCSI initiator as admin. Enter the ip of the target (in the example and hit quick connect. Your target should show up in the Discovered targets section. Click the Volumes and Devices tab and make sure there is something listed in the Volume/Mount point/device section. If not, click Auto Configure. Close the iSCSI tool and head to Explorer. You should see a new drive letter which points to the iSCSi target and you should now be able to move your files to a network or local drive.

Hey, you’re done! That calls for a celebration.

What next?

Once your data is moved off the RAID drives (and verified good!), you could reinstall them in the BA device, reformat and copy the data back, under the hopes that this won’t happen again. Not for me sorry. Fool me once…yada yada.. (of course we now know how to fix it if it happens again…)

You could void your warranty and install a version of linux to replace the OS. Search for “install linux blackarmor” for options. Note the possibility of bricking the unit is reasonably high. I might try this as I certainly won’t be going back to using the BA’s native software. It’s why I’m writing this.

Lastly, you could tuck the debian system you just built with the 4 external drives in a closet or server room and use that as your RAID5 file storage. It’s probably what I’m going to do. NOTE: I’ve added a second post outlining how to do this.

I hope this helps some of you to recover your data and saves you some grey hair!

When ADODB.Recordset variable not defined isn’t due to a missing reference.

Had a really obscure issue this morning that will probably never happen to anyone else but if it does here you go….

I was trying to compile an older access 2003 ADP that we hadn’t compiled for quite a while and it was failing. I opened up the code editor and ran Debug > Compile.

which resulted in Compile Error: Variable Not Defined on the following line



Now normally this is a result of a missing reference. Code Editor > Tools > References

The missing reference for an error on ADODB would be Microsoft ActiveX Data Objects 2.x Library but my application has that reference. Hmmm.

I spent some time adding & removing and changing versions and still nothing. I’m sitting staring at the screen, coffee in hand, when I noticed something.

Can you see it?






Those quotes are wrong. The VBA code editor is plain text. The quotes in the SET statement are extended character quotes. Not sure how they got there. My guess is that when we had to switch CreateObject due to Windows 7 SP1 , the code was emailed in Outlook, copied from a wordpress blog (which likes these types of quotes) or passed around the office in a Word document.

A simple search & replace of the offending quotes with standard quotes resolved the issue.





Windows 7 regional settings & Microsoft Access Errors

We’ve recently been swapping out our old XP machines for new Win7 machines and for the most part things have been pretty smooth (except you HP1020 printer – yes I’m looking at you). However, we did start to run into to some unexplained weirdness. We run an in-house order system built on an Access ADE/Access 2003 Runtime front end & a MSSQL backend. With the latest couple of new machines we started to see some errors, specifically when a user tried to use the MSCAL.OCX Datepicker. (it turns out we hadn’t run into the error before as the new machines were going to non-orderdesk people who didn’t use mscal) Now because users have Runtime & not a full version of Access, debugging these kinds of errors can be a challenge. I have lots of validation & error handling built in for user input issues but Runtime does not provide meaningful error messages on its own so when you run into a system related error, you just get a generic error message (yes there probably are ways to handle those kinds of errors too but not in -my- apps).

Things became even stranger as we found that User A had the error but when User B logged on to the same machine, they were able to use the app just fine. My initial thought was that it was a permissions problem for User A. We checked folder permissions for our app folder and everything seemed fine. We also checked to make sure both users had perms to the Access Program folder (where the OCX resides) and that checked out OK as well. I was tied up with some things so I had my assistant investigate a bit more. After some muttering & swearing (I may be projecting here), he returned to my office and said triumphantly, “Regional settings!”

For some reason User A had regional settings that were different than User B (who had the correct setup) Calendar control didn’t know what to do with the format it was being given so it threw an error.

Firstly, it’s awesome that “my guy” figured this one. In a very long series of assistants, he is the first one even remotely capable of the kind of thinking that finds these kinds of solutions. If you’ve ever uttered the words, “never mind, I’ll fix it myself”, you know what I’m talking about.

Secondly, I ran into this exact error when we made the switch from win200 to XPpro years ago but I didn’t make note of it. Now I have and I’ll be able to find a solution when we make the switch from win7 to win10 in 8 years time. :0

History: By default, IIS websites cannot use the same SSL port (443) for a site using the same IP address. Websites with different IPs can all use port 443. This situation is typical of a standard SSL certificate which is issued to a single host header (ie: Any other attempt to connect to a site via https through a different host header (ie: causes a certificate error (this is by design).

This becomes an issue when trying to install a wildcard SSL certificate. Wildcard certificates provide the ability to secure all subdomains on the root domain using a single certificate. (* examples:

root domain –


However, after you’ve installed a wildcard certificate and try to set up the subdomain to use SSL port 443, you will receive a Port In Use error. You will not be able to start the subdomain websites with the port set to 443. The IIS MMC (inetmgr.mmc) does not provide a method of resolving this so you must use the command line. (Start -> Run -> cmd)

You need to determine the site identifier of the subdomain you wish to modify. To determine <site identifier> Open IIS MMC, click on Web Sites and view the Identifier number next to the subdomain website. In the following script, replace <site identifier> with the number shown in the IIS MMC and change to the subdomain you wish to modify. Run the script with the modifications and you should now be able to browse to with no error.

cscript.exe c:\inetpub\adminscripts\adsutil.vbs set /w3svc/<site identifer>/SecureBindings ""

if you have multiple subdomains, you could create a batch file to run the scripts.
