Building an HA Cluster Configuration
Creating the Logical Volume Infrastructure
Chapter 5160
Storing Volume Group Configuration Data
When you create volume groups, LVM creates a backup copy of the
volume group configuration on the configuration node. In addition, you
should create a backup of configuration data on all other nodes where the
volume group might be activated by using the vgcfgbackup command:
# vgcfgbackup vgpkgA vgpkgB
If a disk in a volume group must be replaced, you can then restore the
disk’s meta data by using the vgcfgrestore command. The procedure is
described under “Replacing Disks” in the “Troubleshooting” chapter.
Also please to be sure to follow the instructions in the “Preventing
Boot-Time VG Scan” section of the Serviceguard for Linux Release Notes.
