HDD shows up as missing in array, but under unassigned devices

[privateer]

Was adding disks to array, swapping out parity, physically moving devices in my box. In the process of all this starting and stopping of arrays and rebooting, I had a drive show up as missing and was listed under unassigned devices. The only option for this drive in unassigned devices is to format it, which I have not done as I have data on this drive.

 

I've swapped SATA cables to the drive as well as power to the drive. No change.

 

I see the below error:

Any ideas on what's wrong? Thinking the disk may be fried but kind of surprised it just crapped out and hadn't thrown off any errors before this that I was aware of.

Please post the diagnostics.

That disk appears to be failing, you can run an extended SMART test to confirm, if it fails replace it.

Command "Execute SMART Extended self-test routine immediately in off-line mode" failed: scsi error medium or hardware error (serious)

 

Any way to recover the data on this drive since I can't start the array (was replacing a parity drive when this died, so no parity). Assuming drive is fried.

 

Additionally, if this drive is dead, can you confirm how I get the array back up without this disk, but maintaining the data on the remaining disks?

Is it tools -> new config -> preserve current assignments (all) that will put the array back up preserving the remaining data on the other disks?

Not without parity, if you still have the old parity maybe, if the disk was OK and parity is still mostly valid, you can also try ddrescue with the failing disk.

Yep.
