HACMP and Filesystems question

Hello all. Yes, I searched the forum first

I have hacmp running on 2 nodes. I wish to add a filesystem to the primary node to and existing shared VG. Not sure how to do this in a cluster environment.

My scenario:
Create the fs in the hacmp screens in smit add in the fs to and existing vg
My vg has 139GB so space is not an issue, I am looking to add a small (10gb) filesystem.

What I am not sure of is how to make sure this is picked up on the secondary node if there is a failover. Will this be done automatically, or do I need to do something specific?

Is the above logic flawed?

As always, thanks for any and all assisance.

Mike

A detailed description would be based on information about the FS and VG type and the HACMP version used. Blind guess: try to create the FS on existing disks in an existing shared standard VG with CSPOC:
# smitty cl_lvm
-> Shared File Systems
-> Add a Journaled File System...
CSPOC will (should... ) promote the changes to all nodes in the resource group of the shared VG.
