ironicbadger Posted May 6, 2015 Share Posted May 6, 2015 Fired up unraid tonight hoping that my data drives (formatted to XFS under Ubuntu) would be picked up and I could just pickup where I left off. Error 'unmountable' is what I'm receiving. I know I could just reformat one drive at a time, but that's a pain. Quote Link to comment
itimpi Posted May 6, 2015 Share Posted May 6, 2015 Unfortunately that will not work. The drive has to have initially been partitioned by unRAID and at that point a signature is written to the drive so that unRAID can recognise a drive it has previously used. Without that unRAID will try and partition the drive to its standard when you first allocate it to the array. Quote Link to comment

trurl Posted May 6, 2015 Share Posted May 6, 2015 I think unRAID has some way to recognize drives that it has partitioned. Don't remember the exact details, but I think that was the problem that came up when we were first testing btrfs cache pools. Maybe something could be done to make the partition unRAID-like. See the beta13 release thread and maybe a solution in the beta14 release thread, but don't know if that solution will apply for you. Quote Link to comment

Your partition table just got overwritten. Quote Link to comment
ironicbadger Posted May 6, 2015 Author Share Posted May 6, 2015 Oh good! Why the F%&& does a simple mount command do that? Jeeez! Quote Link to comment
trurl Posted May 6, 2015 Share Posted May 6, 2015 Oh good! Why the F%&& does a simple mount command do that? Jeeez! I think mounting it at disk1 was probably a bad idea. Don't mess with unRAID managed devices! If you mount them outside the array it might work. Not tried it with XFS drives, but I use the Unassigned Devices plugin (and before that SNAP) to mount NTFS drives all the time. Quote Link to comment
archedraft Posted May 6, 2015 Share Posted May 6, 2015 Not tried it with XFS drives, but I use the Unassigned Devices plugin (and before that SNAP) to mount NTFS drives all the time. I currently have two XFS drives mounted outside of the array (thru the "go" file), although in full disclosure unRAID originally formatted the drives to XFS so I cannot say how the Ubuntu formatted XFS drives would handle...
