Two disks in error mode after boot

[Inflight]

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!

Andy

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.

Thanks for your reply!

 

I see the following:

1. Both disks are connected to the same Mini-SAS x4 (SFF-8087) cable on a LSI SAS 9207-8i controller
2. The discs are just installed next to each other. See image!
3. 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

Syslog resets on reboot which is why he said

You should always try to get diagnostics before rebooting.

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.

They were already disabled in this last boot, this means it happened before.

Maybe you didn't notice they were already disabled before boot.

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?

Shouldn't matter and shouldn't disable disks either way.
