Hi,
I am asking for your help on OCFS2 again.
I can?t figure out a segment of code.
In the function dlm_register_domain which is called during mount procedure,
below code stays:
dlm = __dlm_lookup_domain(domain);
if (dlm) {
if (dlm->dlm_state != DLM_CTXT_JOINED) {
spin_unlock(&dlm_domain_lock);
mlog(ML_ERROR, "fence: dlm(%s) is not joined
yet.\n", dlm->name);
mlog(0, "This ctxt is not joined yet!\n");
wait_event_interruptible(dlm_domain_events,
dlm_wait_on_domain_helper(
domain));
goto retry;
}
I can see that it wants to look up an existed DLM context object which matches
file system?s UUID.
According to my comprehension, DLM context object must be detached from the DLM
domain?s list and released when dismount.
So it?s weird that such a DLM context object can be found at the procedure of
MOUNT.
Could you please provide a clue for me, if convenient?
Many thanks!
BR.
Changwei.
