10. On the other nodes in the cluster, re-read the disk header and scan for the file
system:

NOTE: If vgscan does not find the volume group, you will need to reboot the
node.
11. Create a /clog mount point on each of the other cluster nodes, allowing the clog
package to fail over in case of a node failure:
mkdir /clog
12. Back up the configuration on each node:
vgcfgbackup /dev/vgclog
13. Deactivate the volume group on each node:
vgchange —a n vgclog
