There are pros and cons to this approach - the biggest pro is that you don't have to mirror the entire disk. The biggest con is that only data partitions are mirrored. For details on mirror the mbr, see: http://www.dur.ac.uk/a.d.stribblehill/mirrored_grub.html I haven't tried this but it's referenced by the online Red Hat documentation. > > > Also, if I then insert a blank disk, will it automatically > > > re-generate the > > > data onto it?

Software RAID knows nothing about the MBR - only partitions. -- Ed Wilts, RHCE Mounds View, MN, USA mailto:ewilts@xxxxxxxxxx Member #1, Red Hat Community Ambassador Program -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
