I admit I don't know much about clustering, but from the evidence I see,
the problem appears to be isolated to clvmd and iSCSI, if only for the

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:
Err - possibly a misunderstanding, but GFS/GFS2 doesn't require LVM/CLVM.
You can run on a raw device without volume management.
