I've got a system running on a 13GB drive on /dev/hda. I've got an idential model of drive on /dev/hdb.
The plan is to use something like dump/restore to keep /dev/hdb as a "pretty good" mirror of /dev/hda. (By "pretty good", I mean... it's okay if I lose some log entries, etc.... I just want to be able to get the system back up and running, in the event of a crash, by swapping drives). However, I'd like to avoid having to alter the partition table on /dev/hdb every time I change /dev/hda. Does anyone know of any utilities that allow me to take a "snapshot" of the partition table and write it to another drive? Alternatively, does anyone have any suggestions on other ways to do this same kind of mirroring (except for using md.o, unless you can assure me that it won't cause more problems that it solves...)? - Joe
