January 18, 201610 yr I'm currently running UNRAID 6.1.7 and have been upgrading to new versions on a relatively regular basis (i.e. applying the last 4 or 5 updates within a few days of release and rebooting). The other day I went to watch something on a PC running KODI, a video file that was in my KODI library (meaning it had previously indexed the file), and got the error that the file wasn't found. I went to another computer, checked the share on unraid, and sure enough, I found that I had lost all but 3 files within that particular directory. There would have been around 100 video files total, only 3 remained. I double checked through the unraid web gui, files showing as missing there as well. I'm not terribly upset about the loss of these particular video files, they can always be re-ripped, but I'm concerned about why they were lost, and what else I may have lost that I'm not seeing. Another thing I've noticed, but seemingly unrelated. My cache pool was nearly full - I looked at it, and I had 150gigs of video files sitting there apparently waiting to be moved (files that had been copied to unraid many weeks before). I initiated the mover, no change. I then went to manually move the files only to realize the files already existed in their destination folders. So they had been copied from the cache pool, but never removed. What next steps should I take? I've run a parity check (it completed with zero errors), and my unraid GUI shows no problems with any of my 8 drives (running 8 drives including parity, a combination of 2 and 3TB drives). I've seen reference to Reiserfsck in the unraid forums, should I run this? If so, can someone provide me with the recommended syntax/options of the command for unraid 6.1.7? Getting the files back would be nice, but more importantly I'd like to know why they vanished. Any logs I can be reviewing? Any other suggestions?
January 18, 201610 yr Author Thanks for the link, will give it a shot and report back once I've completed.
January 19, 201610 yr Author I completed a reiserfsck on each of my drives, all report no corruptions found. In looking at the system log that's accessible from the GUI under tools, I am seeing a slew of errors. Any thoughts on the errors below? What are my next steps? After checking all the drives with reiserfsck and re-running my parity check (which again completes with zero errors), my files are still missing. **NEW DEVELOPMENT: Last night I went to watch something from a folder I was viewer 24hrs prior, and it is gone as well. The folder and all sub-folders/files just gone. Probably around 20 files in this case just simply gone. This is in addition to the files missing since I started this post.

January 19, 201610 yr Community Expert On any of the other computers you are using, do you have any drives mapped to your unRAID?
January 19, 201610 yr Author Typically I access via unc, but one of my VMs does have mapped drives, yes
January 19, 201610 yr Community Expert Since parity agrees with your data then I think something is deleting the files. Maybe something can be done with inotify to see what is happening. inotify-tools is in NerdPack then google inotifywatch. I haven't used this.
January 19, 201610 yr Author Thank you, I will look into that. Any comments on the errors above? Should I be concerned about these?
January 19, 201610 yr Community Expert Do you have any counts in the errors column on Main for sde? What does its SMART look like?
January 19, 201610 yr Author yes, SDE is part of the cache pool and needs to be replaced, currently it's just unassigned (not part of the pool). SMART is A-OK across the array.
January 19, 201610 yr Author I pulled my failing, unassigned SSD, and all errors except the kernal tainted errors were resolved. So the only errors left in the log are a bunch of these: Jan 19 10:49:44 zorg kernel: CPU: 0 PID: 1 Comm: swapper/0 Tainted: G I 4.1.15-unRAID #1 Jan 19 10:49:44 zorg kernel: Call Trace: Jan 19 10:49:44 zorg kernel: CPU: 0 PID: 1 Comm: swapper/0 Tainted: G W I 4.1.15-unRAID #1 Jan 19 10:49:44 zorg kernel: Call Trace: Jan 19 10:49:44 zorg kernel: CPU: 0 PID: 1 Comm: swapper/0 Tainted: G W I 4.1.15-unRAID #1 Jan 19 10:49:44 zorg kernel: Call Trace: Jan 19 10:49:44 zorg kernel: CPU: 0 PID: 1 Comm: swapper/0 Tainted: G W I 4.1.15-unRAID #1 Jan 19 10:49:44 zorg kernel: Call Trace: Jan 19 10:49:44 zorg kernel: CPU: 0 PID: 1 Comm: swapper/0 Tainted: G W I 4.1.15-unRAID #1
