LVM > can't do this. Use MD. I know veritas. It has a SubDisk, Plex Volume setup. A subdisk is part of a disk and one or more subdisk make a Plex and one or more plexes make a volume. And a volume can be used as a mount point or whatever. So if a disk goes bad only plexes with use a subdisk from that disk are down. And if a volume has two plex only one need to be up to run. Later the plex can be re-joined back to the volume and the data is synched back to the other plex. In a nut shell what happens when one disk goes down with LVM? Can it be setup to keep the volume up and alive and run and if so what is the best way? > > > -- > If you sit down at a poker game and don't see a sucker, get up. You're > the sucker.
