This will depend on exactly what it is you want to achieve.

I assume you are talking about increasing the size of an LV in one of the cluster VGs? If that is the case, then no, you don't need to do anything else. As long as you did not add a drive to the VG or add an LV to the VG you are OK. When you extend an LV the new size will be automatically picked up when the VG is activated on the other node.

Increasing a filesystem always requires two steps: making the lvol larger using lvextend (but the filesystem knows nothing about this change) and then extendfs (requires filesystem to be unmounted) to inform the filesystem that a change has been made. If you purchased the optional Online JFS product, you can do this in one step (without unmounting the filesystem) using fsadm (only for VxFS filesystems).

With "other steps" I would intend some modification on cluster config
( please, forgive me but i'm a beginner on MCSG ) .
BTW , than to all

If all your doing is increasing an existing lvol no MCSG changes are required. Lvextend & extendfs as all you need.

The control scripts activate the vg & mount the lvol which already exist.

If you have created a new lvol ... thats a different matter.

perfect.
Thanx to all guys!
