Tagging – Simple Example

• Every machine in the cluster has tags { hosttags = 1 }

• You want to activate vg1/lvol2 only on host db2.

• Run lvchange --addtag @db2 vg1/lvol2 from any host in the cluster.

• Run lvchange -ay vg1/lvol2.

• This solution involves storing hostnames inside the VG metadata.
