Hello guys! Looking for maybe a bit of clarity on why this may have happened. Monthly Parity check kicked off last night @2:00 April 1st. When I checked this morning I noticed that 3 consecutive disks had equal numbered read errors, as well as sync errors, all at 128. I've looked through the syslog a bit but not 100% sure what I might be looking for. One thing that stood out was that my weekly appdata backup kicked off at the same time and happened to finish at almost the exact moment the read errors stopped. I've adjusted the scheduling for that now in case it caused a problem. Other than that, nothing glaring stood out. Also the 3 disks in question looked healthy in smart data. The 3 disks were also not dropped from the array, so it seems Unraid was able to recover.
Any thoughts on this? From memory, I don't recall ever having any sync/read errors before, so I was a bit surprised. Might some random file be corrupted because of this? I've attached a copy of the syslog, as well as the smart data for the 3 disks and a screenshot of my dashboard. The machine has been up for 29 days so there should be lots of historical data in there. Any help would be appreciated, thanks in advance! Parity check is still running currently btw, at 18% now.
