Hi,
I'm trying mount a GFS2 disk using the clustering in Fedora 8 but
gfs_controld dies (see below).
For example:
# service cman start (ver. 6.0.1 config 20)
Starting cluster:
Loading modules... done
Mounting configfs... done
Starting ccsd... done
Starting cman... done
Starting daemons... done
Starting fencing... done
[ OK ]
# mkfs.gfs2 -t home:gfs -p lock_dlm -j 2 /dev/drbd0
This will destroy any data on /dev/drbd0.
Are you sure you want to proceed? [y/n] y
Device: /dev/drbd0
Blocksize: 4096
Device Size 4.00 GB (1048535 blocks)
Filesystem Size: 4.00 GB (1048532 blocks)
Journals: 2
Resource Groups: 16
Locking Protocol: "lock_dlm"
Lock Table: "home:gfs"
; Check that gfs_controld is running (as you see it is)
ps -ef|grep gfs

root 6081 1 0 09:32 ? 00:00:00 /sbin/gfs_controld
; Now try to mount it:
# mount -t gfs2 /dev/drbd0 /net -o
locktable=home:gfs,lockproto=lock_dlm -vv
mount: no LABEL=, no UUID=, going to mount /dev/drbd0 by path

/sbin/mount.gfs2: parse_opts: lockproto = "lock_dlm"
/sbin/mount.gfs2: parse_opts: locktable = "home:gfs"

Segmentation fault
; My kernel is:
"2.6.24.4-64.fc8PAE" but get the same results on another machine
running: "2.6.23.8-63.local.fc8"
The drive DOES mount OK with "lockproto=lock_nolock"
The underlying device is DRBD block device (ver 8.2.5) which is backed
by a /dev/loop3 file device, but I'm sure that has nothing to do with
this problem (as ext3, XFS work OK as well as GFS2 with lock_nolock).
Any clues ?
TIA,
Albert.
