Note

If there are multiple logical volumes in the volume group, then the logical volume name

(lv_name) in the lvm resource should be left blank or unspecified. Also note that in an

HA-LVM configuration, a volume group may be used by only a single service.

4. Edit the volume_list field in the /etc/lvm/lvm.conf file. Include the name of your root

volume group and your hostname as listed in the /etc/cluster/cluster.conf file

preceded by @. The hostname to include here is the machine on which you are editing the

lvm.conf file, not any remote hostname. Note that this string MUST match the node name

given in the cluster.conf file. Below is a sample entry from the /etc/lvm/lvm.conf file:

volume_list = [ "VolGroup00", "@neo-01" ]

This tag will be used to activate shared VGs or LVs. DO NOT include the names of any

volume groups that are to be shared using HA-LVM.

5. Update the initrd device on all your cluster nodes:

# mkinitrd -f /boot/initrd-$(uname -r).img $(uname -r)

6. Reboot all nodes to ensure the correct initrd device is in use.
