[Ocfs2-users] Trouble getting node to re-join two node cluster (OCFS2/DRBD Primary/Primary)

[Mike Reid]

I may have made some progress on my OCFS2 error:

See the following output from ³dmesg²

[88740.345617] OCFS2: ERROR (device drbd0): ocfs2_validate_inode_block:
Invalid dinode #11: fs_generation is 376662488

[88740.346124] ocfs2: Unmounting device (147,0) on (node 0)


I decided to run ³fsck.ocfs2 -F /dev/drbd0²:

Checking OCFS2 filesystem in /dev/drbd0:
  label:              <NONE>
  uuid:               fe 42 73 e1 f8 66 45 41 bb cf 66 c5 df d4 96 d6
  number of blocks:   24999936
  bytes per block:    4096
  number of clusters: 24999936
  bytes per cluster:  4096
  max slots:          8

/dev/drbd0 wasn't cleanly unmounted by all nodes.  Attempting to replay the
journals for nodes that didn't unmount cleanly
Checking each slot's journal.
Replaying slot 0's journal.
Slot 0's journal replayed successfully.
Slot 0's local alloc replayed successfully
/dev/drbd0 is clean.  It will be checked after 20 additional mounts.
Slot 0's journal dirty flag removed


Unfortunately, I still cannot mount the fs....

> mount -t ocfs2 /dev/drbd/by-res/repdata /data
