let’s say the cluster name is “mynamran” and the shared storage device is mapped to /dev/mapper/mpath0
so the command to create GFS2 partition is as below :
mkfs.gfs2 -p lock_dlm -t mynamran:gfs2 -j 8 /dev/mapper/mpath0
then to test mount it .. to a /gfs2
mount -o acl -t gfs2 /dev/mapper/mpath0 /gfs2
any node which is members of “mynamran” cluster will be able to mount this
storage simultaneously ..
some other tools to test
gfs2_tool list
gfs2_tool df
woohoo..!
it shall however.. un-mounted before machine goes off.
hence.. is recommended putting this into /etc/fstab
current working setting is as below
/dev/mapper/mpath0 /gfs2 gfs2 defaults,noatime,nodiratime 0 0
there option to actually mount the GFS2 partition via cluster suite..
but that probably for just the active node .. which somehow defeat the purpose.. of enabling it to actually having multiple node
accessing same storage.. without NFS.. :)
