Appendix A. Upgrading GFS
To upgrade a node to Red Hat GFS 6.1 from earlier versions of Red Hat GFS, you must convert
the GFS cluster configuration archive (CCA) to a Red Hat Cluster Suite cluster configuration
system (CCS) configuration file (
/etc/cluster/cluster.conf
) and convert GFS
pool
volumes
to LVM2 volumes.
This appendix contains instructions for upgrading from GFS 6.0 (or GFS 5.2.1) to Red Hat GFS
6.1, using GULM as the lock manager.
Note
You must retain GULM lock management for the upgrade to Red Hat GFS 6.1;
that is, you cannot change from GULM lock management to DLM lock
management during the upgrade to Red Hat GFS 6.1. However, after the
upgrade to GFS 6.1, you can change lock managers.
The following procedure demonstrates upgrading to Red Hat GFS 6.1 from a GFS 6.0 (or GFS
5.2.1) configuration with an example
pool
configuration for a pool volume named
argus
.
poolname argus
subpools 1
subpool 0 512 1 gfs_data
pooldevice 0 0 /dev/sda1
1. Halt the GFS nodes and the lock server nodes as follows:
a. Unmount GFS file systems from all nodes.
b. Stop the lock servers; at each lock server node, stop the lock server as follows:
# service lock_gulmd stop
c. Stop
ccsd
at all nodes; at each node, stop
ccsd
as follows:
# service ccsd stop
d. Deactivate pools; at each node, deactivate GFS
pool
volumes as follows:
