Red Hat Bugzilla – Bug 592125
[LSI CR178786] - clvmd init script is run at the same stop level as gfs & gfs2, causing shutdown to fail
Last modified: 2010-11-09 07:46:25 EST
Description of problem: - 2 Nodes RHCS setup. Both nodes are running RHCS and servicing the gfs. We are seeing the following every time one of the nodes is powering down from a node reboot. openais[6111]: [TOTEM] The consensus timeout expired. openais[6111]: [TOTEM] entering GATHER state from 3. The node will never shutdown; this output will be printed forever. The only way to get the node back up is physically power it off and back on. Version-Release number of selected component (if applicable): Kernel Release: 2.6.18-194.el5 RHEL Release: Red Hat Enterprise Linux Server release 5.5 (Tikanga) Version: Linux version 2.6.18-194.el5 (mockbuild@ppc-008.build.bos.redhat.com) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-48)) #1 SMP Tue Mar 16 22:03:12 EDT 2010 Platform: ppc64 How reproducible: Often. Steps to Reproduce: 1. 2 RHEL5.5 PPC servers. 2. Connected to 2 storages. 3. Created 4 volumes from each storage and mapped to cluster group of the 2 servers. 4. RHCS is installed on both servers. 5. Setup the RHCS and also using GFS. 6. Reboot one of the nodes Actual results: The node repeatedly reporting the following message during shutdown sequence: openais[6111]: [TOTEM] The consensus timeout expired. openais[6111]: [TOTEM] entering GATHER state from 3. openais[6111]: [TOTEM] The consensus timeout expired. openais[6111]: [TOTEM] entering GATHER state from 3. Expected results: Node shutdown and boot back up without any issue.

Any Updates?
Abdel - is this ppc specific, or can it be reproduced on other arches as well?
After some testing and log file analysis, I'm really NOT sure if this is problem of openais. It *can* be problem of clvm (Can't deactivate volume group "lvm_vg" with 8 open logical volume(s)), init scripts, or maybe cman (Error leaving cluster: Device or resource busy). But fact is, that openais will never receive shutdown signal (cman is responsible for that). I'm reassigning bug to cman. Chrissie, if you will feel that this problem IS problem of openais, please reassign bug back to me.
As Honza says, this is all down to the fact that clvmd can't deactivate the logical volumes. Without that happening there is a whole dependency of things that can't shut down. So the first thing to investigate is what is holding those volumes open. There is also the side-issue that sending signals to openais does not shut it down.
For answering the issue is seeing on different architects, we have also seen this issue on x64 and ia64.
any updates?
The log messages from openais are not valid indicators of this failure: Stopping cman... failed This will mean that openais does not shutdown. When openais doesn't shutdown and the network interfaces are later stopped, openais will print the messages in the log. Not an openais problem.
Wow.

Clvmd is stopping at 74 instead of 76 - at the same level as gfs/gfs2. It should be stopping at 76 (after gfs/gfs2).
Performing the following allows clvmd to stop at the right time (i.e. after gfs/gfs2 are unmounted by their respective initscripts): * Remove "Required-Stop: $local_fs" from /etc/init.d/clvmd * chkconfig --del clvmd * chkconfig --level 345 clvmd on Changing component to lvm2-cluster.
Steve Dake noticed that this works as expected on later releases. It turns out that /etc/init.d/netfs "Provides: $local_fs" on Red Hat Enterprise Linux 5, but not on later releases of Fedora or Red Hat Enterprise Linux 6 Beta. This provision interferes with chkconfig, which reorders the initscripts based on the "Provides:" information at the top of the script.
Created attachment 428565 [details] Example fix. After applying this patch to /etc/init.d/netfs, clvmd will be stopped at level 76 as expected, which is after the gfs/gfs2 init scripts.
After applying the above patch to /etc/init.d/netfs, you must perform: * chkconfig --del clvmd * chkconfig --level 345 clvmd on ... in order to reset the links.
But how did it choose to set them at the same level if there's a dependency between them? Is the gfs script missing 'Required-Stop: clvmd' (and Required-Start too)? And is clvmd missing a dependency on cman?
I'd agree... changing this in initscripts seems fishy, not the least because some app may rely on that provide in RHEL 5.

You're right, Bill. Turns out it was a regression in lvm2-cluster.
