A parallel umount on 4 nodes triggered a bug in dlm_process_recovery_date(). Here?s the situation:
Receiving MIG_LOCKRES message, A node processes the locks in migratable lockres. It copys lvb from migratable lockres when processing the first valid lock.
If there is a lock in the blocked list with the EX level, it triggers the BUG. Since valid lvbs are set when locks are granted with EX or PR levels, locks in
the blocked list cannot have valid lvbs. Therefore I think we should skip the locks in the blocked list.

Looks reasonable.
Just wanted to confirm. Did this BUG_ON in dlmrecovery,c get tripped?
1903 /* otherwise, the node is sending its
1904 * most recent valid lvb info */
1905 BUG_ON(ml->type != LKM_EXMODE &&
1906 ml->type != LKM_PRMODE);

Sorry, I haven't described it clearly.
We trigger the BUG() in dlmrecovery.c:1923.
Lockres had copyed lvb from previous valid locks and then meet with another lock with the EX level.
1907 if (!dlm_lvb_is_empty(res->lvb) &&
1908 (ml->type == LKM_EXMODE ||
1909 memcmp(res->lvb, mres->lvb, DLM_LVB_LEN))) {
......
1923 BUG();
1924 }

"There is shadow under this red rock.

And I will show you something different from either
Your shadow at morning striding behind you
Or your shadow at evening rising to meet you.
I will show you fear in a handful of dust."

Hello Guys
I create on my VMware two virtual machine connected via FC to EMC storage
with ocfs2.
After few hours cp, rm, mv, du ?sh, quota ?v root and other command on this
file system i get oops mayby that help You guys with diagnose problem:
If You need i can give You access to both this server via SSH.
