Out of nowhere disk 10 got disabled but I don't see any of the normal disk dying errors. I reconnected it since that's usually the issue but when I tried a rebuild, disk 5 got disabled. I don't want to continue without some guides from you guys on what the issue could be. It's been working fine on the same hardware for like 7 months straight. From checking the disk log and googling the error I don't know of it's a power issue or the LSI needing an upgrade. It could be failing but I didn't see any smart issues. I'm going to start backing up those 2 disks just in case till I get some insight thanks.

To somewhere off the array I hope. Better if you don't write a lot of data to the array when it is degraded. You should always have another copy of anything important and irreplaceable anyway. Parity is not a substitute for backups.

 

Diagnostics shows disk5 rebuilding and disk10 disconnected and is now the unassigned disk sds. SMART for both looks OK, though neither have had any self-tests. Both emulated disks are mounted and show plenty of data. These appear to be on separate controllers, though the same model.

 

Don't see any problems with disk5 rebuild, but of course, disk10 rebuild has quit and it is disabled again. Looks like a connection issue.

 

 

Really appreciate the super quick reply. Yeah I have 2 LSI cards both should be identical and about 7 months ago (like November 2024 or October) I upgraded the power supply for more satas. Havnt touched it since but all of a sudden that disk 10 got disabled. Usually I see some smart and I document each drive but I don't have previous issues with them besides faulty connection due to that previous power supply.

 

A general question. Just thinking here. Hypothetically, if i set 1 disk as 'none'm could I rebuild 1 of 2 disks? Is that a thing? If 2 disks are emulated can you rebuild another disk in this state or do both disks have to be rebuilt at the same time? I have had unRAID for like 7 years and thankfully haven't had 2 disks emulated let alone rebuild two at once.

yes

You can just let disk5 rebuild continue, it has already disabled disk10 again and it isn't involved anymore.
