64 Appendix A. Upgrading GFS
d. Deactivate pools; at each node, deactivate GFS
pool
volumes as follows:
#
service pool stop
e. Uninstall Red Hat GFS RPMs.
2. Install new software:
a. Install Red Hat Enterprise Linux version 4 software (or verify that it is in-
stalled).
b. Install Red Hat Cluster Suite and Red Hat GFS RPMs.
3. At all GFS 6.1 nodes, create a cluster configuration file directory (
/etc/cluster
)
and upgrade the CCA (in this example, located in
/dev/pool/cca
) to the new Red
Hat Cluster Suite CCS configuration file format by running the
ccs_tool upgrade
command as shown in the following example:
#
mkdir
/etc/cluster
#
ccs_tool upgrade /dev/pool/cca /etc/cluster/cluster.conf
4. At all GFS 6.1 nodes, start
ccsd
, run the
lock_gulmd -c
command, and start
clvmd
as shown in the following example:
#
ccsd
#
lock_gulmd -c
Warning! You didn’t specify a cluster name before --use_ccs
Letting ccsd choose which cluster we belong to.
#
clvmd
Note
Ignore the warning message following the
lock_gulmd -c
command. Because the
cluster name is already included in the converted configuration file, there is no need
to specify a cluster name when issuing the
lock_gulmd -c
command.
5. At all GFS 6.1 nodes, run
vgscan
as shown in the following example:
#
vgscan
Reading all physical volumes. This may take a while...
Found volume group "argus" using metadata type pool
6. At one GFS 6.1 node, convert the
pool
volume to an LVM2 volume by running the
vgconvert
command as shown in the following example:
#
vgconvert -M2 argus
Volume group argus successfully converted
7. At all GFS 6.1 nodes, run
vgchange -ay
as shown in the following example:
#
vgchange -ay
1 logical volume(s) in volume group "argus" now active
