Default Re: Howto hot-add a new PV into an existing concurrent mounted VG

Phil,

Don't agree.

If you have it on one system in the CONCURRENT VG, you have a
semi-corrupted situation. If the extendvg fails and the disk is only
av. on 1 side you have a prob. already. YOu should remove it from the
vg (reducvg off course) and then try it again from the other node (that
is what I meant with trying it again !) to avoid the 111111 sit.
