A few months ago I swapped my SATA cards for a HBA as I had been getting UDMA CRC errors. Everyting has been fine since, but I had to shutdown the server today for the first time and on restart, one of my parity drives is disabled. SMART looks OK to me (but I'm not an expert). Is there anything to be concerned about here? Do I just need to rebuidl parity?

Disk was already disabled at boot so we can't see what happened, but it looks healthy, I would replace cables to rule that out and re-sync.

OK, I stopped, restarted with P2 unselected, stopped again, reslected P2 and started. It was rebuilding parity this morning, but I just checked it and it has write errors in the logs, and it says it's paused at 1.7% of a parity check.

 

In the Array Operations tab I only have reboot, shutdown and sleep.

 

Whast my best course of action here? Can I reboot, and then deselct P2? Will it need to rebuild parity on P1? I'd be happy with single parity for now if it gets me up and running.

Did you replace the cables as suggest? Minimum swap cables with a different disk and try again.

yeah, I've done that now and it's rebuilding. The Array operaions tab has only 3 buttons and the main tab still has dropdowns, even though it's doing a rebuild. Is that as expected?

Nope, GUI is out of sync, try opening it with a different browser, not Firefox, still possibly will need to reboot to get it to show correct.

It’s happening with Safari too. Not to worry. It’s 75% of the way through the rebuild so we’re looking good. Thanks for your help @JorgeB!

Rebuild has completed successfully. A reboot has fixed the Array Operations tab too. Maybe it’s time for an update. 
 

thanks again for your help!
