I'm not sure whether it's an issue or not anymore. I discontinued using
gfs2 because I could not get the kernel panic to go away.

Subject: [Bug 1020207] Re: gfs2 kernel oops when deleting file as first action after mounting 

Dave Spano, this bug was reported a while ago and there hasn't been any 
activity in it recently. We were wondering if this is still an issue? If 
so, could you please test for this with the latest development release 
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com 
/daily-live/current/ . 

If it remains an issue, could you please run the following command in 
the development release from a Terminal 
(Applications->Accessories->Terminal), as it will automatically gather 
and attach updated debug information to this report: 

apport-collect -p linux <replace-with-bug-number>

If reproducible, could you also please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: 
kernel-fixed-upstream 
kernel-fixed-upstream-VERSION-NUMBER 

where VERSION-NUMBER is the version number of the kernel you tested. For example: 
kernel-fixed-upstream-v3.13-rc6 

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: 
needs-upstream-testing 

If the mainline kernel does not fix this bug, please add the following tags: 
kernel-bug-exists-upstream 
kernel-bug-exists-upstream-VERSION-NUMBER 

As well, please remove the tag: 
needs-upstream-testing 

Once testing of the upstream kernel is complete, please mark this bug's 
Status as Confirmed. Please let us know your results. Thank you for your 
understanding.

Title: 
gfs2 kernel oops when deleting file as first action after mounting 

Status in “linux” package in Ubuntu: 
Incomplete 

Bug description: 
I have an active/active drbd cluster with pacemaker running on cman. 
If I create a file on the shared gfs2 file system on one node, then 
try to delete it on the other, I'm receiving this kernel panic. I get 
the same error on both nodes, so it's not specific to either machine.
