I avoid #1 because my SAN can do snapshots of individual LUNs only; i.e., there is no way to get a consistent snapshot of an LV composed of multiple PVs on multiple LUNs. I also have a completely irrational fear of losing just one of the LUNs. Only #1 and #3 can be accomplished without downtime, but you can't do #3... unless [4] Create a new, larger LUN; pvmove all data there; and drop the original LUN. -- Rich Graves http://claimid.com/rcgraves Carleton.edu Sr UNIX and Security Admin CMC135: 507-222-7079 Cell: 952-292-6529 _______________________________________________ rhelv5-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/rhelv5-list
