Hi,

Well  gfs_tool should be used on the gfs blocks INSIDE of the logical 
volumes,
which are inside the volume groups, which are all part of lvm.
So perhaps the problem is that you specified the physical devices rather 
than
the logical volumes.  I'm very sorry if I misled you here.  You want to 
do something like this:

gfs_tool sb /dev/VolGroup03/lvol0 table qm:gfs1

Where /dev/VolGroup03/lvol0 is a logical volume defined to be in a 
volume group
VolGroup03, which contains the physical volumes that correspond to your
hardware.
