TOPIC:

Has anyone had experience with expanding their ISCSI/DRBD storage repository. I know there are different steps and procedures for "online" expansion of DRBD and "offline" expansion and there are also differences with the meta data being internal or external. The stock setup of ha-lizard and iscsi-ha setups up an internal meta data.

Essentially should I be able to reboot the server (HP dl380 gen 9) expand the hw raid backend with the hp raid utility and then boot up the server into xen and do the online DRBD storage expansion process?
