Description Robert Peterson 2007-10-30 22:14:45 UTC

+++ This bug was initially created as a clone of Bug #350571 +++
Crosswriting from RHEL4 to RHEL5.

On a shared root fs you cant get a lockdump by doing a gfs_tool lockdump / 
because /proc/mounts looks like this

rootfs on / type rootfs (rw)
none on /dev type tmpfs (rw)
/dev/vg_zhlr421_sr/lv_sharedroot on / type gfs (rw,noatime,nodiratime)


This patch resolves the problem.

Same problem on RHEL5 with gfs{,2}_tool?

Comment 1 Robert Peterson 2008-06-12 20:23:12 UTC

I believe this is now fixed by virtue of bug #431951 and bug #431952
which are co-requisites.  I still haven't heard back on the RHEL4 parent
bug #350571 so I'm just going to assume it's fixed and close this one.
If we need to do a code change later, we'll open up another bug record
at that time.
