I am trying to mount a hard drive that has been previously used in another device that had the drive formatted as XFS. I have tried to research the error, but I cant find any solution to the exact problem I am facing.

Running sudo blkid shows the drive at /dev/sdh*

/dev/sdh1: UUID="a09d6417-3771-4ad5-a35d-90e8c5f8b3dd" BLOCK_SIZE="512" TYPE="xfs" PARTUUID="8db76c67-01"
/dev/sdh2: PARTUUID="8db76c67-02"
/dev/sdh5: UUID="061935cf-e4f9-4c03-8543-ae08e44ec4c5" BLOCK_SIZE="512" TYPE="xfs" PARTUUID="8db76c67-05"
/dev/sdh6: PARTUUID="8db76c67-06"
/dev/sdh7: TYPE="swap" PARTUUID="8db76c67-07"
/dev/sdh8: TYPE="swap" PARTUUID="8db76c67-08"

and running

sudo mount -t xfs /dev/sdh1 /mnt/data

gives the error

mount: /mnt/data: unknown filesystem type 'xfs'.

I have tried running xfs_repair on the drive but it errors out giving

Phase 1 - find and verify superblock...
xfs_repair: filesystem has a realtime subvolume
xfs_repair: realtime device init failed
xfs_repair: cannot repair this filesystem.  Sorry.

Does anyone know why I cant mount the drive?

  • This answer on U&L SE and the comments there. Does it help? – Kamil Maciorowski Dec 18 '20 at 1:25
  • Thanks for the response, but unfortunatly not. I saw that article before and it was no help. After following the instructions for live mounting the drive, I still receive mount: /media/data: unknown filesystem type 'xfs'. – Canadian Bacon Jan 8 at 20:49
  • So as per the U&L question you've confirmed that your xfs module is loaded? Because you shouldn't get the "unknown filesystem" message if it is loaded. Also it should auto-load, but I suspect it's not and figuring out why will lead to your answer. – grifferz Jan 25 at 15:19
