7. Start the CCS daemon (ccsd) on all the nodes.
Note
This step must be performed each time the cluster is rebooted.
The CCA device must be specified when starting ccsd.
n01#
ccsd -d /dev/pool/alpha_cca
n02# ccsd -d /dev/pool/alpha_cca
n03#
ccsd -d /dev/pool/alpha_cca
lck01# ccsd -d /dev/pool/alpha_cca
lck02#
ccsd -d /dev/pool/alpha_cca
lck03# ccsd -d /dev/pool/alpha_cca
8. At each lock server node, start the LOCK_GULM server:
lck01# lock_gulmd
lck02#
lock_gulmd
lck03# lock_gulmd
Note
The lock server nodes,
lck01
,
lck02
, and
lck03
,were specified in the
cluster.ccs
file earlier.
9. Create the GFS file systems.
Create the first file system on
pool_gfs01
and the second on
pool_gfs02
. The names of the
two file systems are
gfs01
and
gfs02
, respectively, as shown in the example:
n01#
gfs_mkfs -p lock_gulm -t alpha:gfs01 -j 3 /dev/pool/pool_gfs01
Device: /dev/pool/pool_gfs01
Blocksize: 4096
Filesystem Size:1963216
Journals: 3
Resource Groups:30
Locking Protocol:lock_gulm
Lock Table: alpha:gfs01

All Done
n01#
gfs_mkfs -p lock_gulm -t alpha:gfs02 -j 3 /dev/pool/pool_gfs02
Device: /dev/pool/pool_gfs02
Blocksize: 4096
Filesystem Size:1963416
Journals: 3
Resource Groups:30
Locking Protocol:lock_gulm
Lock Table: alpha:gfs02
