After rebuild, disk is Unmountable: Unsupported or no file system

Featured Replies

History:

1. Lost disk 3 due to hardware failure.

2. Replaced with larger disk and successfully performed parity swap process.

3. Successfully rebuilt disk 3 (which was the old parity disk) but it's now showing as unmountable.

 

My disks are btrfs encrypted.

 

Please can you help?

 

Thanks, Kevin.
