[Ocfs2-users] Problems building ocfs2 rpm on Fedora 9

[Tina Soles]

P.S., I also executed the following, and get the same results for UUID
and ls -l on both nodes:

OK, so I mounted the disk from node 1, using:

mount -t ocfs2 -o nointr /dev/sdb1 /ocfs2/oradata/orcl 

works great:

#mount
/dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/sda1 on /boot type ext3 (rw)
tmpfs on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
fusectl on /sys/fs/fuse/connections type fusectl (rw)
gvfs-fuse-daemon on /root/.gvfs type fuse.gvfs-fuse-daemon
(rw,nosuid,nodev)
configfs on /sys/kernel/config type configfs (rw)
ocfs2_dlmfs on /dlm type ocfs2_dlmfs (rw)
/dev/sdb1 on /ocfs2/oradata/orcl type ocfs2
(rw,_netdev,nointr,heartbeat=local)

however, trying to execute the same command from node 2 results in the
following:

mount -t ocfs2 -o nointr /dev/sdb1 /ocfs2/oradata/orcl
mount.ocfs2: Device or resource busy while mounting /dev/sdb1 on
/ocfs2/oradata/orcl. Check 'dmesg' for more information on this error.

dmesg on node 1 shows:

ocfs2: Mounting device (8,17) on (node 0, slot 0) with ordered data
mode.

192.168.0.28:7777

dmesg on node 2 shows:

Do I have something configured incorrectly, or do I need an additional
option in my mount command?

Thanks....

datavolume mount option is only on ocfs2 for enterprise kernels.

For most part, you shouldn't require it for using it as a datastore.
Instead set init.ora param filesystemio_options to directio (or is it
odirect).

The only bit that won't work here is using ocfs2 for the voting disk and
ocr... as datavolume is necessary to force enable odirect.
But you can always use raw for that.
