[Ocfs2-users] heartbeat and slot issues.

[brad hancock]

Thanks for the response.
Is it normal for when I change it on one node, the other node reflects the
same UUID?


node1:
tunefs.ocfs2 -q -Q "BS=%5B\nUUID=%U\n" /dev/sdb1
BS= 4096
UUID=ea0778bd-bdaa-44af-8fbf-cb4a5d85e79f


node2:
 tunefs.ocfs2 -q -Q "BS=%5B\nUUID=%U\n" /dev/sdb1
BS= 4096
UUID=ea0778bd-bdaa-44af-8fbf-cb4a5d85e79f
