cmapplyconf -k -v -C /etc/cmcluster/clust1.conf
or
cmapplyconf -k -v -C /etc/cmcluster/clust1.ascii
NOTE: Using the -k option means that cmapplyconf only checks disk
connectivity to the LVM disks that are identified in the ASCII file. Omitting the
-k option (the default behavior) means that cmapplyconf tests the connectivity
of all LVM disks on all nodes. Using -k can result in significantly faster operation
of the command.
• Deactivate the cluster lock volume group.
vgchange -a n /dev/vglock
The cmapplyconf command creates a binary version of the cluster configuration file
and distributes it to all nodes in the cluster. This action ensures that the contents of the
file are consistent across all nodes. Note that the cmapplyconf command does not
distribute the ASCII configuration file.
NOTE: The apply will not complete unless the cluster lock volume group is activated
on exactly one node before applying. There is one exception to this rule: a cluster lock
had been previously configured on the same physical volume and volume group.
After the configuration is applied, the cluster lock volume group must be deactivated.
Storing Volume Group and Cluster Lock Configuration Data
After configuring the cluster, create a backup copy of the LVM volume group
configuration by using the vgcfgbackup command for each volume group you have
created. If a disk in a volume group must be replaced, you can then restore the disk's
metadata by using the vgcfgrestore command. The procedure is described under
“Replacing Disks” in the “Troubleshooting” chapter.
Be sure to use vgcfgbackup for all volume groups, especially the cluster lock volume
group.
