Hi, I installed the Fix Common Problems plugin just to make sure everything was ok with my unraid server, and amongst a couple of other issues which I'm ok dealing with, it said there was a machine check error. I followed the advice and installed mcelog, then downloaded diagnostics (attached). I rebooted the server and the issue is still there. Any ideas what it is and how to resolve it?

Thanks for the reply. Hopefully that was it. All the currently unassigned disks were from my old server. Was mounting them under an Ubuntu VM with ZFS to copy the contents across to Unraid. They will all become part of the Unraid array soon, but was holding off for a little while in case something went wrong, so I had a backup.

New diagnostics from after restart. undelta-diagnostics-20210704-1947.zip

So... I powered off the server, unplugged and re-plugged all the drive and power cables, then started up again. The previously inaccessible disk is now accessible and I can read data from it, but not sure if there is any corruption on that disk. Is there any way to find out? Any way to find out what the actual issue was and if it will happen again?

Hi, I'm new to Unraid and have no idea what to do about these errors. I recently finished moving all my data from a previous server, and haven't got my parity disk in place yet. Last night the server did a read check and filled the syslog (100%) with read errors for Disk 3, and I can't access that disk at all. I aborted the read check when I discovered the log was full. SMART stats all seem fine to me. Running an extended self test, but it doesn't seem to be doing much? Started off saying 10% complete and hasn't changed for over 30 mins. Diagnostics attached. Any help on what I can do about this would be much appreciated. Thanks. undelta-diagnostics-20210704-1214.zip UPDATE: The extended self test "completed" - at least it no longer says it's running, but the Last SMART test result says "No self-tests logged on this disk"
