[Ocfs2-users] Re: Mounting multiple clones

[Kendall, Kim]

After upgrading ocfs2, I was able to use the -U option to recreate the
UUID on the LUNs. There may/will be issues if another LUN with the same
UUID is already mounted (even on another node in the cluster).

I commented all luns out of the fstabs and rebooted all the nodes in the
cluster, then I could run the tunefs.ocfs2 -U on all the devices without
any problems.

-K

Hi Kim,
I'm having the same problem, did you solve this problem using tune.ocfs2
-U?
I'm trying to reset uuid on a ocfs2 device using ocfs2 1.2.4.

[root at node01 ~]tunefs.ocfs2 -U /dev/dm-4
tunefs.ocfs2 1.2.4

ocfs gave me this error
tunefs.ocfs2: Trylock failed while locking down the cluster.


/dev/dm-4 is not a mounted filesystem, do you have any  idea?


Thank you...



Antonio
