Neither GFS or GFS2 volumes cannot be shrunk. Eventually I
need to start working on a gfs2_shrink tool for gfs2, but I
don't think GFS will ever be able to shrink.
As for growing, it sounds like you're already familiar with
that. You just do something like:
lvresize or lvextend the logical volume
mount the gfs volume to a mount point
It's probably safest to do gfs_grow when there is not a lot of
system activity. For example, at night when the system is not
being beat up by lots of I/O.
