Unmountable: Unsupported partition layout

[Valafar]

I have had to replace a faulty disk and installed it back into the system but it will not mount I get the following message "Unmountable: Unsupported partition layout", I have tested this new drive in my windows system and it works perfectly, any ideas?

 

I attach the diagnostic logs.

Your description is very incomplete and suggests you aren't doing it right, but your diagnostics do give some clues. The main thing that is confusing me is the error message itself. Post a screenshot showing that message.

Hi Trurl,

I attach 2 screenshots which should help hopefully, I have tried restarting the server.

Thanks

DO NOT agree to FORMAT anything or you will lose the data from that disk.

 

The disk in your diagnostics looks fine so you can rebuild to that disk. And you will have to repair the filesystem. Not sure which should be done first.

 

@johnnie.black I know I have wondered this before, but is it generally better to rebuild the disk then repair the filesystem, or repair the emulated filesystem then rebuild the disk?

OP already formatted the disk, the unsupported partition error in this case is strange, first because it's an emulated disk, so Unraid should have created a partition, second because after the disk was formatted it's still complaining.

 

Unfortunately on my way out so not much time to look into this, try unassigning the disk, starting the array with disk2 empty and see if it mounts, though if it does it will be empty 'cause of the format, so if you still have the old disk intact keep so for now.

the problem was the array was not rebuilding, however I just restarted unraid twice, without the new disk first time and then adding it back, after I restarted the array the rebuild started, so all good.

Thanks

the new disk

Just to be clear, you have the old disk that unraid kicked from the array intact, correct? You will need it to attempt to recover your data, since you formatted the disk slot in unraid.

thanks, the data is intact, I had 3 disks in a raid formation, so all ok, just needed to get the 3rd disk back in.

thanks all

Unraid is not RAID, and each disk is an independent filesystem. Just because you can see files on some user shares doesn't mean you didn't lose the data on disk2. Was disk2 supposed to be empty?
