July 4, 20215 yr Hi guys, I'm on vacation but got some concerning notifications from unRAID l night. Both my parity drives had been disabled within the same minute, I've got errors all over and a warning on my cache drive. I'm afraid to stop the array or reboot. Any advice?

July 4, 20215 yr The Unraid WebUI is not reliable. Might be this time... I would be shitting if I saw that in the morning. Wait... I've seen that shit. Relax... You have a backup and everything will be fine after another vacation spent restoring everything from the backup. My wife would say it's no problem at all, and I need to cut the lawn. 6

July 4, 20215 yr Community Expert There were errors in multiple disks: Jul 3 21:43:36 Tower kernel: md: disk4 read error, sector=8177890032 Jul 3 21:43:36 Tower kernel: md: disk1 read error, sector=8177890032 Jul 3 21:43:36 Tower kernel: md: disk2 read error, sector=8177890032 Jul 3 21:43:36 Tower kernel: md: disk6 read error, sector=8177890032 Jul 3 21:43:36 Tower kernel: md: disk8 read error, sector=8177890032 Jul 3 21:43:36 Tower kernel: md: disk0 read error, sector=8177890032 Jul 3 21:43:36 Tower kernel: md: disk29 read error, sector=8177890032 Also the cache device, could be a connection/power problem or HBA problem.
July 4, 20215 yr Community Expert Forgot to mention, unrelated to this issue but the server was running out of RAM for some time before this, you should also look into that.
July 14, 20214 yr Author I ended up shutting the system down from vacation. When I came back I re-seated all cables to SAS-expanders and booted again. Parity was marked as invalid. I did a read-check of the array which went without errors. Then I stopped the array, unassigned the parity drives, started the array, stopped the array, assigned parity drives again. It re-built both parity drives without errors, and is seemingly running well now. I'll pay attention to the RAM usage going forward. Thanks.
