Inflight Posted August 2, 2021 Share Posted August 2, 2021 Dear community This morning, two disk (one parity, one array disk) have been marked as failed (error mode and spinned down) after boot of the unraid server. I had the same behavior several times a few month ago. Then I replaced the main board and installed a stronger power supply. Also the SATA cables have been replaced. Since then, I never had an issue and the host was super stable! Please find the diagnostics attached to this topic. Any help is highly appreciated! Thanks in advance!

JorgeB Posted August 2, 2021 Share Posted August 2, 2021 Disks were already disable at boot, so we can't see what happened, check if they have something in common other than the controller, like a power splitter, etc. Quote Link to comment
Inflight Posted August 3, 2021 Author Share Posted August 3, 2021 (edited) Thanks for your reply! I see the following: Both disks are connected to the same Mini-SAS x4 (SFF-8087) cable on a LSI SAS 9207-8i controller The discs are just installed next to each other. See image! They are NOT connected to the same power cable of the power supply. A look at the syslog shows that all disks at boot (about 06:00) spun up and were imported. Later, they were spun down. But I don't know where to see when the errors occurred. Do I overlook something? Any further ideas? best regards Andy Edited August 3, 2021 by Inflight additional info Quote Link to comment

Inflight Posted August 4, 2021 Author Share Posted August 4, 2021 Hmm, that‘s what I did. I did not reboot the tower after I have seen the two disks in error state. I pulled the diagnostics then. Quote Link to comment
JorgeB Posted August 4, 2021 Share Posted August 4, 2021 They were already disabled in this last boot, this means it happened before. Quote Link to comment

Inflight Posted August 4, 2021 Author Share Posted August 4, 2021 I checked my shutdown script and realized, that I used ‚shutdown -h now‘ instead of ‚/sbin/poweroff‘ to power down the tower. Could that have been the cause for those disk errors? Quote Link to comment
trurl Posted August 5, 2021 Share Posted August 5, 2021 Shouldn't matter and shouldn't disable disks either way. Quote Link to comment
