Hi Joseph,
Again we are facing same issue. Please find the logs when the problem
occurred.
Dec 27 21:45:44 integ-hm5 kernel: (dlm_thread,46268,24):dlm_update_lvb:206
getting lvb from lockres for master node
Dec 27 21:45:44 integ-hm5 kernel:
So which process hangs? And which lockres it is waiting for?
From the log I cannot get those information.

On
If system hangs, you should figure out which process as well as its
stack before restarting the system.

HI Joseph,
Our current setup is having below details and DLM is now allowed (DLM
allow). Do you suggest any other option to get more logs.
debugfs.ocfs2 -l
DLM off ( DLM allow)
MSG off
TCP off
CONN off
VOTE off
DLM_DOMAIN off
HB_BIO off
BASTS off
DLMFS off
ERROR allow
Please also switch on BASTS and DLM_RECOVERY.

Hi Joseph,
I have enabled requested and Is the DLM log will capture to analyze
further. Also do we need to enable network side setting for allow max packets.
debugfs.ocfs2 -l
DLM allow
MSG off
TCP off
CONN off
VOTE off
DLM_DOMAIN off
HB_BIO off
BASTS allow
DLMFS off
ERROR
So you mean the four nodes are manually rebooted? If so you must
analyze messages before you rebooted.
If there are not enough messages, you can switch on some messages. IMO,
mostly hang problems are caused by DLM bug, so I suggest switch on DLM
related log and reproduce.
You can use debugfs.ocfs2
Ok, thanks

I don't think there is relation with packet size.
Once reproduced， you can share the messages and I will try my best if
free.

Dear Team,
Ocfs2 clients are getting hang often and unusable. Please find the
logs. Kindly provide the solution, it will be
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.
