November 29, 20241 yr Having an issue with a drive being unmountable after I made some configuration changes. Unraid OS is version 6.10.3, array consists of 6 (4TB) drives, 1 parity and 5 data drives. Ok so let's do a sequence of events here so someone can tell me where I messed up. Drive 1 fails Purchase a replacement drive that's 8 TB because why not Remove failed drive and install new, larger drive Start system and select new larger drive in the slot of the failed drive (Drive 1) System explains to me why I'm obviously stupid for trying to add a larger drive than the existing parity drive Do some reading online and see that solution is to swap the larger drive to the parity slot and put the original parity drive in the failed drive slot (or at least that's how I understood it) Do that and initiate a parity copy. Copy succeeds. 8 TB drive is now the parity drive. Old parity drive is now in the Drive 1 slot (old failed drive) Start the array and let the parity check go. Parity check finishes after 12 ish hours so I'm guessing the parity check has rebuilt the data on Drive 1 Array starts fine but I get an error message on Disk 1 saying "Unmountable: Wrong or no file system". Info for Disk 1 is showing XFS as the file system. This is where I'm at. I see a check box at the bottom in the Array Controls area to format unmountable drives and I thought that might be the solution except that A) The drive was already formatted as it was the parity drive and is showing as XFS so I'm not sure if that's the issue, and B) when I check that box to format the message specifically states that this is not part of the recovery process for a failed drive and that if I do this it will just blank that drive and I won't be able to rebuild it to it's pre-failed state. At this point I'm not sure what to do or what is wrong in my thinking here. Any and all help is appreciated.
