DeltaMike Posted July 4, 2021 Share Posted July 4, 2021 (edited) 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" Edited July 4, 2021 by DeltaMike Updated with self test info Quote Link to comment
DeltaMike Posted July 4, 2021 Author Share Posted July 4, 2021 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? Quote Link to comment

trurl Posted July 4, 2021 Share Posted July 4, 2021 Those look good so far. You seem to have only 4 disks assigned to the array, none disabled and all are mounted. But you have a large number of Unassigned. Is that expected? It was probably just a connection problem, very common, and maybe you have fixed it. Quote Link to comment
DeltaMike Posted July 5, 2021 Author Share Posted July 5, 2021 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. Quote Link to comment
