BurningSky Posted October 16, 2023 Share Posted October 16, 2023 (edited) Hoping someone might be able too help me here. I've had a few issues recently with Unraid, but a chunk of them seemed to end up being down to a bad SSD in my cache pool which I have now taken out of the pool (but is still in the server for now). I had noticed that my parity disk was showing increasing numbers of errors but it would flucuate up and down and seemed to settle after the changes I made recently (replaced the SSD with SMART issues and swapped out my SAS coontroller). However, yesterday there were ~3000 errors on parity and now there are over 9000! I've taken a quick look in the syslog and I've started to see these errors repeating: Oct 16 05:26:35 Ragon kernel: I/O error, dev sdd, sector 3019156232 op 0x0:(READ) flags 0x0 phys_seg 29 prio class 2 Oct 16 05:26:35 Ragon kernel: md: disk0 read error, sector=3019156168 Oct 16 07:37:41 Ragon kernel: I/O error, dev sdg, sector 1016 op 0x0:(READ) flags 0x0 phys_seg 1 prio class 2 Oct 16 07:37:41 Ragon kernel: md: disk4 read error, sector=952 sdd is in there a lot more, which is the parity disk, so looks like it might been failing, which is annoying as it's only a year or so old. Wondering if anyone could take a look and suggest if there are any other issues other than 2 failing disks, there aren't any SMART errors on either disk.

JorgeB Posted October 16, 2023 Share Posted October 16, 2023 Parity looks more like a power/connection issue, replace cables, disk4 may be failing, run an extended SMART test. Quote Link to comment

Thanks for that, I'll check the cables for the parity disk. What did you notice in the logs that led you to believe that? Quote Link to comment
