[Ocfs2-users] problem stopping o2cb service on one of nodes

[Nikola Ciprich]

Hello Tao,
and thanks a lot for reply!
It seems not to be the same bug, at least applying the patch didn't help.
stopping hb using -K parameter really helps, but why doesn't this work automatically
on umount?
it always happens on the second node...
I don't see any error in logs, anything.
But the reference count always increases on mount, and doesn't decrease on umount on this node..
