lvm is not a clvm ;)

LVM is not cluster aware so be very careful !

Steps to make changes on a (shared-) lvm:

  1. other nodes: # vgchange -an
  2. master node: make changes like # lvrename
  3. other nodes: # vgscan; vgchange -ay

Thats on only necessary if you have a shared storage like drbd or a SAN 😉
