Created attachment 913001 [details] Related log parts from two nodes. Description of problem: We are experiencing cluster GFS2 hang ups shortly (usually in a couple of minutes) after booting the new kernel 3.14.8-200.fc20.x86_64. This happens basically on all nodes, see the log attached. Version-Release number of selected component (if applicable): kernel-3.14.8-200.fc20.x86_64
Hi Milos, This problem is undoubtedly due to the fact that the Fedora kernel is missing this upstream patch: http://git.kernel.org/cgit/linux/kernel/git/steve/gfs2-3.0-nmw.git/commit/fs/gfs2/meta_io.h?id=1b2ad41214c9bf6e8befa000f0522629194bf540 The question now becomes: What to do about it?
Ah, that's funny, I had a look at recent changes in gfs2 at kernel.org and looking at this commit I thought: well, this is something that might very well caused the bug. And it is vice versa. Is there anything that would prevent merging the patch into Fedora kernel?
Hi Milos, The kernel package has been rebased to the 3.15.3 stable kernel in the updates-testing repository. That version includes the patch Bob mentioned in comment #1. Are you able to try out that kernel? If so, you can update to it using: # yum update --enablerepo=updates-testing kernel kernel-modules-extra I'm not sure when the rebase is planned to arrive in the stable repository but testing it out and adding karma to the Bodhi record* can only help to bring that time forward. * https://admin.fedoraproject.org/updates/FEDORA-2014-8017/kernel-3.15.3-200.fc20 Thanks!
Dear Andrew, thanks a lot -- we shall have a slot to try out next Tuesday, I will get back then. Milos
Hi Andrew, the testing has been succesful. The bug didn't occur. Thanks. Jan

It looks like the 3.15.3 kernel package is in the stable repository now so I'm closing this bug per the above. If the same bug reoccurs, feel free to reopen it. Thanks.
