June 11, 20206 yr Hello! Hoping someone might be able to assist with this issue, as I've searched (and tried) several different options, but to no avail. This all started when I recently upgraded my parity drive (from a 3tb WD to a 4tb Seagate). The obvious answer is that something is wrong with the drive, but I'm not sure. The array starts up fine, no errors of any kind, and the server runs normally for about a day. Then, all of the drives (including the USB boot drive) disappear from the array. Sometimes I get an "Array Undefined" message in the lower left of the browser, sometimes not. Sometimes I can see the shares, sometimes they're gone. When the shares are missing I can't access the files through my Mac, but Plex can continue to run normally. I changed the cables, updated the USB drive, and upgraded from 6.4 to 6.8, but the same issues remain. I've attached a few images along with this post, as they are the only error messages I've been getting. I have no Dockers and no VMs, the only app I have installed is the Community App plug-in. Any thoughts would be greatly appreciated! Jay
June 12, 20206 yr Community Expert Go to Tools - Diagnostics and attach the complete Diagnostics ZIP file to your NEXT post.
June 12, 20206 yr Author I had to restart the server, so I'm not sure if what we're looking for is in this diagnostic file or not. If not, I'll wait for the problem to occur again and get that file. tower-diagnostics-20200611-1907.zip
June 12, 20206 yr Community Expert It could be that the USB drive is dropping offline for some reason. How do you have it plugged in? have you tried making a ssh connection to the server when the problem occurs? If you can then that might help with investigating what has happened.
June 12, 20206 yr Author So, run diagnostics from the terminal on my Mac? Assuming that is correct, I will do that the next time the array disappears and post the diagnostics report here. Edited June 12, 20206 yr by dabrosis

Assuming that is correct, I will do that the next time the array disappears and post the diagnostics report here. That is an option using the 'diagnostics' command from the terminal session. Another option would be to try df ls -l /boot ls -l /mnt ls -l /mnt/user to check that the flash drive is still online and that the the standard mount points look OK.
June 14, 20206 yr Author I don't think I'm well versed enough to know what I'm looking for. Entering each of those four separately I get this: 1.

June 14, 20206 yr Community Expert The output from the commands looks as expected. did you try running the ‘diagnostics’ command via the ssh session? If that completed successfully there would be a zip file created in the ‘logs’ folder on the USB drive that would tell us a lot more about the state of your system. If that does run attach the zip file to your next post.
June 14, 20206 yr Author Here is a diagnostics test from yesterday, taken while the array was having issues. I pulled it from the logs folder on the flash drive. tower-diagnostics-20200613-1701.zip Edited June 14, 20206 yr by dabrosis
June 16, 20206 yr Author Well, for whatever reason the array seems to have stabilized itself. It's been up for almost 48 hours now, without issue, and that's easily the longest it's been up since all this began. Thanks for all the help!
