F.2. Configuring HA-LVM Failover wit h T agging

To set up HA-LVM failover by using tags in the /etc/l vm/l vm. co nf file, perform the following

steps:

1. Ensure that the l o cki ng _type parameter in the global section of the

/etc/l vm/l vm. co nf file is set to the value '1'.

2. Create the logical volume and file system using standard LVM and file system commands, as

in the following example.

# pvcreate /dev/sd [cd e]1

# vgcreate shared _vg /d ev/sd [cd e]1

# l vcreate -L 10 G -n ha_l v shared_vg

# mkfs. ext4 /d ev/shared _vg /ha_lv

For information on creating LVM logical volumes, refer to Logical Volume Manager

Administration.

3. Edit the /etc/cluster/cluster. co nf file to include the newly created logical volume as a

resource in one of your services. Alternately, you can use Co n g a or the ccs command to

configure LVM and file system resources for the cluster. The following is a sample resource

manager section from the /etc/cl uster/cluster. co nf file that configures a CLVM

logical volume as a cluster resource:

<rm>

</failoverdomain>

</failoverdomains>

<fs name="FS" device="/dev/shared_vg/ha_lv" force_fsck="0"

force_unmount="1" fsid="64050" fstype="ext4" mountpoint="/mnt"

options="" self_fence="0"/>

</resources>

<service autostart="1" domain="FD" name="serv"

recovery="relocate">
