Hello. 2 disks in my array seem not to be working. Both SMART tests seem okay, but 1 shows as "unmountable", and the other is "disabled, contents emulated". How can I determine if they are dead, or get them back in the array properly?

 

Attached are diagnostic zip and screenshot.

 

Thanks in advance.

The SSD looks OK and it was already disable prior to this boot, probably a bad cable, the problem is that disk1 has pending sectors and you can't rebuild because you already have a disable disk and only single parity, so you're likely going to lose some data, best bet would probably be to clone disk1 to a spare disk with dd and hope there's only a few bad sectors, then depending on if you know how long the SSD has been disable adn if data is unchanged since rebuild or do a new config, finally run xfs_repair on disk1.

 

P.S.: parity disk has several CRC/ATA errors on the log, most likely needs a new SATA cable.

Thanks a ton. 

Another option that should be easier and just as good as long as there's no important data on the SSD, or if you can still copy it from the emulated disk before doing it:

 

-rebuild the SSD, some data will be corrupt because of the disk1 read errors

-replace disk1, again some data will be corrupt because of the previous errors, but same as if you use dd to skip the bad sectors

-run xfs_repair on disk1
