You can access different LVs in the same SAN shared VG presumably you make changes to the VG (eg: create, resize LVs) when it is active (vgchange -ay) on one of them only. After done with the changes, run vgscan and "vgchange -ay" on the other machine. > > -- > Regards, > > Wiktor Wodecki > > _______________________________________________ > linux-lvm mailing list > linux-lvm@sistina.com > http://lists.sistina.com/mailman/listinfo/linux-lvm > read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/ -- Regards, Heinz -- The LVM Guy -- *** Software bugs are stupid.
