bibly Posted July 15, 2021 Share Posted July 15, 2021 Hello all As per title, I was in the middle of doing the parity swap and changing a parity drive to a data disk with a subsequent upgrade to the parity drive using the steps in the guide. The issue is that after step 5, whilst replacing the smaller 2TB drive, I managed to damage another (5TB) drive in my server (sata port). As a result Unraid now has 2 missing drives since it had already forgotten the old 2TB drive and I can't start the array even if I reassign the old 2TB to it's original slot. My questions are: 1. Is it possible to get Unraid to 'rememeber' the 2TB again? 2. Would I actually need to start Unraid without both drives, and then implement a rebuild in the old 2TB, and then bring the 6TB in? 3. As I am looking to replace the parity in slot 1 with a 6TB parity drive, is there another quicker way to resolve this issue? Thanks in advance. Quote Link to comment
JorgeB Posted July 15, 2021 Share Posted July 15, 2021 It might be possible to recover, if the array disks are using xfs (or reiser), but you need a disk of the same size of the missing disk to configure the array, disk doesn't need to be healthy but it needs to be detected. Quote Link to comment

Disk system is XFS but not sure I can detect it as there is physical damage. Quote Link to comment
JorgeB Posted July 15, 2021 Share Posted July 15, 2021 The you'd need to get another disk of the same size since parity was also 5TB, alternatively you could clone the old parity to the new 6TB disk with dd then use that one for disk1. Quote Link to comment
bibly Posted July 15, 2021 Author Share Posted July 15, 2021 Would it be easier to simply rebuild on the 2TB (as I have dual parity and can recover from that) and then do the parity swap on the damaged drive? Quote Link to comment
