You may want to run a full fsck on the fs.<div><br></div><div>fsck.ocfs2 -fy /dev/xxxx<br><br><div class="gmail_quote">On Tue, Aug 21, 2012 at 12:49 AM, Pawel <span dir="ltr"><<a href="mailto:pzlist@mp.pl" target="_blank">pzlist@mp.pl</a>></span> wrote:<br>

After upgrading ocfs2 my cluster is instable.<br>
<br>
At least ones per week I can see:<br>
kernel panic: Null pointer dereference at 00048<br>
o2dlm_blocking_ast_wrapper + 0x8/0x20 [ocfs2_stack_o2cb]<br>
stack:<br>
dlm_do_local_bast [ocfs2_dlm]<br>
dlm_lookup_lockers [ocfs2_dlm]<br>
dlm_proxy_ast_handler<br>
add_timer<br>
..<br>
<br>
After that sometimes deadlock happens on another nodes. Entire cluster<br>
restart solve the issue.<br>
I see in log:<br>
(dlm_thread,7227,3):dlm_send_proxy_ast_msg:484 ERROR:<br>

<br>
<br>
Additionaly ~4 times per day I see:<br>

ocfs2_create:629 ERROR: status = -17<br>
<br>
<br>
I currently use kernel 3.4.2<br>
my filesystem has been created with:<br>
-N 8-b 4096 -C 32768 --fs-features<br>
backup-super,strict-journal-super,sparse,extended-slotmap,inline-data,metaecc,xattr,indexed-dirs,refcount,discontig-bg,unwritten,usrquota,grpquota<br>
<br>
Could you tell me what could make my system instable? Which feature ?<br>
<br>
Thanks for any help<br>
<br>
Pawel<br>
