Corosync was getting hang while starting/stopping. I read in one of the redhat site that use cman to manage corosync. So, I started using cman.
Please help.

Version-Release number of selected component (if applicable): cman-3.0.12.1-68.el6.x86_64.rpm

# more /etc/system-release

kernel/fs/configfs/configfs.ko has nothing to do with corosync/cman. I'm pretty sure it's problem in your configuration (not completed depmod, corrupted module, ...). Dmesg shows anything interesting? Kernel update helps?

Comment 3 Christine Caulfield 2015-01-19 09:08:13 UTC
DLM (part of the cman package) uses configfs to communicate between userspace and the kernel module. Without that it won't be able to start.

So it sounds to me like a corrupted kernel installation. Try reinstalling the package or upgrading it. It's not specifically a cman problem as Honza says, it's to do with the kernel package installation.

it's worth trying to re-run "depmod -a", also see if "modprobe -v configfs" shines any more light on why it's failing. If you get desperate an strace of the command might also help.

But I would begin with reinstalling or upgrading the kernel package.

As this bug has been inactive for nearly six months I'm going to close it. If there's any more information then feel free to re-open it so we can have a look.
