There is a race window to triger BUG in dlm_drop_lockres_ref. all nodes will hang in the futhure. Node 1 Node 3 mount.ocfs2 vol1 and create node lock, reboot waiting for Node 3 Node 3 mount.ocfs2 vol1 fail to mount vol1, do not get lock on journal fail to mount vol1, Local alloc hasn't been recovered! dlm_drop_lockres_ref and lockres don't exsit, return Error -22 and triger BUG. I think the BUG should be removed for the case. But i can't say for sure what will come and remove the BUG?

After reboot everything is come to normal, this behavior happend many times. Do we have any debug and fix for this issue. Regards Prabu ---- On Tue, 22 Dec 2015 16:30:52 +0530 Joseph Qi <joseph.qi@huawei.com>wrote ---- Hi Prabu, From the log you provided, I can only see that node 5 disconnected with node 2, 3, 1 and 4. It seemed that something wrong happened on the four nodes, and node 5 did recovery for them. After that, the four nodes joined again.

So simply removing the BUG is not a fair way to resolve this issue. And I don't think the log you pasted can actually refer to its node. Node 3 is indeed the deref handler because it is owner but not node 1. BTW, if you want others to do the review and give you more suggestions, you'd better follow the way described in Documentation/SubmittingPatches.

* [Ocfs2-devel] [Ocfs2-users] Ocfs2 clients hang 2015-12-28 6:49 ` Joseph Qi @ 2015-12-28 8:17 ` Zhangguanghui 0 siblings, 0 replies; 3+ messages in thread From: Zhangguanghui @ 2015-12-28 8:17 UTC (permalink / raw) To: ocfs2-devel Thanks for replys, The root of the problem may lie in node 1 that has baen retried to create lock, and although node 3 has been dead. node 1 mount vol1, dlm_send_remote_lock_request has been Error -92 send CREATE LOCK to node 3. while node 3 that has mounted vol1 fence and reboot. node 1 fail to mount and dismount vol1, and then dlm_drop_lockres_ref send msg to node3, for node 3, dlm_deref_lockres_handler may return EINVAL while mounting vo1. ________________________________ zhangguanghui From: Joseph Qi<mailto:joseph.qi@huawei.com> Date: 2015-12-28 14:49 To: zhangguanghui 10102 (CCPL)<mailto:zhang.guanghui@h3c.com> CC: ocfs2-devel<mailto:ocfs2-devel@oss.oracle.com>; Siva Sokkumuthu<mailto:sivakumar@zohocorp.com> Subject: Re: [Ocfs2-users] Ocfs2 clients hang dlm_deref_lockres_handler may return EINVAL or ENOMEM which will lead to sender BUG. So simply removing the BUG is not a fair way to resolve this issue. And I don't think the log you pasted can actually refer to its node. Node 3 is indeed the deref handler because it is owner but not node 1. BTW, if you want others to do the review and give you more suggestions, you'd better follow the way described in Documentation/SubmittingPatches.
