Installation guide

Note
If there are multiple logical volumes in the volume group, then the logical volume name
(lv_name) in the l vm 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 vol ume_li st field in the /etc/l vm/lvm. co nf file. Include the name of your root
volume group and your hostname as listed in the /etc/cl uster/cl uster.co nf file
preceded by @. The hostname to include here is the machine on which you are editing the
l vm. co nf file, not any remote hostname. Note that this string MUST match the node name
given in the cl uster. co nf file. Below is a sample entry from the /etc/l vm/lvm. co nf 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 i ni tramfs device on all your cluster nodes:
# d racut -H -f /bo o t/i ni tramfs-$(uname -r). i mg $(uname -r)
6. Reboot all nodes to ensure the correct ini trd device is in use.
