[Linux-cluster] /sbin/mount.gfs thinks fs is gfs2?



I am upgrading a system with a GFS 6.0 filesystem from RHEL 3 to CentOS 5, 
and subsequently GFS 6.0 to 6.1.  I've followed the instructions here:
http://www.redhat.com/docs/manuals/csgfs/browse/rh-gfs-en/ap-license.html
and subsequently ran gfs_tool sb device proto lock_dlm on my gfs lv

The cluster is up and quorate, and clvmd sees the gfs lv, but when I try 
to mount it, I get:

#  mount -t gfs -o upgrade /dev/mapper/pool_gfs-pool_gfs /VAULT10/
/sbin/mount.gfs: there appears to be a GFS2, not GFS, filesystem on 
/dev/mapper/pool_gfs-pool_gfs

I'm not sure why this is failing.  For grins, I tried mounting it as a 
gfs2 filesystem and this is what I get:

#  mount -t gfs2 -o upgrade /dev/mapper/pool_gfs-pool_gfs /VAULT10/
/sbin/mount.gfs2: there appears to be a GFS, not GFS2, filesystem on 
/dev/mapper/pool_gfs-pool_gfs

I have successfully performed the upgrade if I use centos 4 as an 
intermediate step in the upgrade and perform the upgrade steps there and 
the conversion from lock_gulmd to dlm.  However, there are several 
clusters we need to do this with, so that's a painful option to avoid if 
possible.  

Here is the output from gfs_tool:
