Is that one big xfs filesystem? Are you able to mount with krbd?

Hi There,

We are replicating a 100TB RBD image to DR site. Replication works fine.

rbd --cluster cephdr mirror pool status nfs --verbose

health: OK

images: 1 total

    1 replaying

 

dir_research:

  global_id:   11e9cbb9-ce83-4e5e-a7fb-472af866ca2d

  state:       up+replaying

  description: replaying, master_position=[object_number=591701, tag_tid=1, entry_tid=902879873], mirror_position=[object_number=446354, tag_tid=1, entry_tid=727653146], entries_behind_master=175226727

We then, use nbd to map the RBD image at the DR site but when we try to mount it, we get


# mount /dev/nbd2 /mnt

mount: block device /dev/nbd2 is write-protected, mounting read-only

mount: /dev/nbd2: can't read superblock



We are using 12.2.8.


Any help will be greatly appreciated.


Thanks,

-Vikas
