I admit I don't know much about clustering, but from the evidence I

Will let LVM folks comment on rest of the issues. However, if you intend
to use this as single node case, are you aware that both GFS and GFS2
support a "lock_nolock" protocol that doesn't require CLVMD ? It can be
run on a plain storage device (say /dev/sda1) and doesn't have any
locking overhead. Do a "man gfs_mkfs" and search for "LockProtoName". A
sample mkfs-mount command looks like the following:
shell> gfs_mkfs -t my_cluster:gfs1 -p lock_nolock -j 1 /dev/sda1
shell> mount -t gfs /dev/sda1 /mnt/gfs1
