I'm having some trouble with my current DrivePool, here is my configuration:
System: Core 2 Duo E8400 3Ghz, 8Gb memory, P4C800-Deluxe motherboard with the latest BIOS, Corsair HX520 PSU.
Drives:
2x Hitachi 2Tb
2x Western Digital Red 3Tb
2x Western Digital Green 2Tb
1x Seagate 500G (System drive, not pooled)
The 2 Hitachi's and 2 Reds are plugged in to a Promise SATA300 TX4 card, the other 3 are plugged into the motherboard.
OS: Windows 8 Pro 64-bit
Initially everything installed ok and files were copying fine. I have mainly media files as well as documents and pictures stored here. I also run CrashPlan, so everything except my movies are also backed up to their cloud. I back 3 other systems up to a folder in the pool using CrashPlan (with duplication - wondering if this causes any problems?), and 1 other using Windows Backup. Duplication is turned on for most folders, including these.
The first symptom I saw was StableBit Scanner noticed some S.M.A.R.T. errors on one of my Green drives. I set it up so that if errors were seen that it would not store unduplicated data. When looking at this drive, all contents were marked as Other. I removed this drive from the pool seemingly without issue.
Next, I began having issues with permissions on one of the 3Tb Red drives, where it would be completely inaccessible (double clicking a drive would return "No access to device - you do not have permission"). I found that if I took ownership and ensured that the SYSTEM, System Administrators and my own login ID had Full Control I could regain access to the drive. Once that was done, I noticed again that the contents of the disk was now marked as Other. I tried to remove this drive but it would not remove. I rebooted the machine a couple times to see if that would help, and the situation worsened...badly. At this point only 1 of the Red drives shows up, it's labelled Local Disk and is asking me to format it when I try to open it (which I did not do, obviously).
I shut down the server again, removed both 3Tb drives, and plugged them into my Windows 7 desktop. Same thing. 1 won't show up, the other displays an uninitialized file system. I shutdown again and plugged them in one by one to see which one was which, identified the one with the uninitialized filesystem, and then when I plugged in the other a large stream of "deleting orphaned file part ####" streamed by followed by what looked like some repair, including a bunch of my pictures. When it finally got to Windows, the drive shows up and reports that only 18G are in use (after looking for what that 18G consisted of, I could only manage to find 18MB of some CrashPlan backups and some empty folders under PoolPart. I am currently executing a CHKDSK on this drive with both Automatically fix file system errors and Scan for and attempt recovery of bad sectors checked.
Would someone be able to help me figure out what happened? Which component of my setup failed? Both 3Tb drives "seem" fine, neither reported any errors (I have StableBit Scanner installed/licensed as well) but both now have no data on them at all (for now, I'll see if CHKDSK can find anything and return it). Was it something DrivePool did? Is the Promise card at fault? Is Windows 8 to blame? It doesn't seem the drives are bad, they're both quite new (one of them only a couple weeks old, the other I had running in the same server under WHS 2011 for about 6 months). I'm really stumped as to what could cause such a catastrophic failure.
I'm thankful I didn't put anything crucial on this pool without a cloud backup of it (the software is marked Beta after all), but had I not I would have incurred some significant data loss.
