The "gfs_tool sb /dev/etherd/e1.1 proto" does return lock_dlm as the lock protocol.
Which package contains the gfs_edit tool?
Thanks again,
Tom

Hi Tom,
Another thought. If someone went in there without your knowledge and
did something bad
like mkfs.ext3 /dev/etherd/e1.1 (or mkfs.vfat, reiserfs, xfs, jffs2, or
whatever)
or worse, the underlying device, it would also manifest itself as the
problem you're seeing.
If it were me, I'd do: "gfs_edit /dev/etherd/e1.1" and have a look at
block 0.
The gfs_edit tool starts you out on block 0x10 (the superblock), so
you'll have to do 16
"b" keystrokes or else arrow up and change block number to 0 and press
enter. The first
16 blocks of the file system should be all zeros, 0x00. If they look
like a bunch of numbers
instead, then maybe somebody overwrote your file system. BTW, gfs_edit
is a dangerous
tool so don't change anything with it.
