7.0.1 to 7.1.1 - Unmountable: Unsupported or no file system can't downgrade

  • Solved
  • Urgent

I set one nvme as cache pool and i put /appdata and docker img in this pool.

When upgrading from 7.0.1 to 7.1.1 the drive reports "Unmountable: Unsupported or no file system"

Tried to run

xfs_repair -n /dev/nvme0n1

output:

...

found candidate secondary superblock...
unable to verify superblock, continuing...

Sorry, could not find valid secondary superblock
Exiting now.

 

And now I can't downgrade to 7.0.1, is there any methods to fix this?

 

Thanks.
