I've seen these problems too while using the rpms.  I don't think that
this is a packaging issue... it might be a kernel issue.  I've not
been able to recreate this problem 100% of the time.  I've also seen
the following message while loading the gfs module (when lock_harness
wasn't already loaded):

    gfs: no version for "lm_mount" found: kernel tainted.

Comment 2 Chris Feist 2005-01-05 20:35:13 UTC

I think the issue is in RHEL3 & FC3 you can include
/lib/modules/<kern-version>/build, but in RHEL-4 you need kernel-devel
package & the files are in /lib/modules/<kern-version>.  I'm working
on the build scripts for the kernel rpms so they put things in the
right spot (ie. /lib/modules/<kern-version>/cluster instead of in
/lib/modules/<kern-version>/build/cluster).

I've also noticed that you only get the tainted message the first time
you modprobe a module with a problem.  It seems like once the kernel's
tainted there's no un-tainting.  (Which is why you only see one 'no
version for "xxx"' messages).

Comment 3 Adam "mantis" Manthei 2005-01-05 21:03:44 UTC

Nevermind... I'm going to blame Chris again.  I can get it everytime
now just as Derek was before (I think the reason I couldn't was
because /etc/rc.sysinit was trying to automatically mount my gfs
filesystems):

Currently waiting on bug #145358.

Comment 5 Chris Feist 2005-01-25 23:32:36 UTC

This bug has been fixed in dlm-kernel-2.6.9-11.3 & cman-kernel-2.6.9-13.1.

Comment 6 Derek Anderson 2005-01-31 16:32:42 UTC

Verified in dlm-kernel-2.6.9-14.1 and cman-kernel-2.6.9-15.1.
