stuckless Posted January 8, 2023 Share Posted January 8, 2023 The SMART shows OK, and the last parity check (7 days ago) showed OK, but now the drive is showing READ errors and is disabled. About a month ago, I noticed the same issue, and I removed and then re-aded the partity drive and it added/rebuilt fine, but now I'm back to this again. Is this a bad disk? Something else goin on? Hopefully someone smarter than me can see something in the logs. Thanks for any help. mediaserver-diagnostics-20230108-0806.zip Quote Link to comment
JorgeB Posted January 9, 2023 Share Posted January 9, 2023 Disk dropped offline so there's no SMART report but this is usually a power/connection problem, post new diags after a power cycle. Quote Link to comment
stuckless Posted January 9, 2023 Author Share Posted January 9, 2023 By a power/connection issue, do you think it could be power supply issue? Bad cable? loose cable? I'll open up the box and reseat all the power connectors, and then re-run a diag and post it here. Thanks, Sean. Quote Link to comment
JorgeB Posted January 9, 2023 Share Posted January 9, 2023 Could be any of those. Quote Link to comment
stuckless Posted January 9, 2023 Author Share Posted January 9, 2023 I adjusted all the sata cables and power cables and rebooted. here's the new log. The drive is still disabled. Does that mean that the system thinks it is physically not there? mediaserver-diagnostics-20230109-1736.zip Thanks Quote Link to comment

Once a drive is disabled (because a write to it failed) then it normally stays disabled until the drive is rebuilt. Quote Link to comment

SMART report for the disk is in the diagnostics, so it was there when diagnostics were taken. 14 minutes ago, itimpi said: stays disabled until the drive is rebuilt. Quote Link to comment

trurl Posted January 9, 2023 Share Posted January 9, 2023 Just now, trurl said: so it is out-of-sync and has to be rebuilt. same whether data or parity disk. Quote Link to comment
stuckless Posted January 10, 2023 Author Share Posted January 10, 2023 Thanks I'll rebuild. This is the second time in 2 months that I'll be rebuilding the parity drive. Wish I fully understood why this was happening Thanks for help. Much appreciated. Quote Link to comment
Solution trurl Posted January 10, 2023 Solution Share Posted January 10, 2023 Check connections, SATA and power, both ends, including splitters. Don't put more than 4 disks on a single power cable. Don't bundle data cables. Make sure all cables have enough slack so they can sit squarely on the connection without any tension. Try a different cable if the same one keeps causing problems.
