I have a server with 2 disks that are not mirrored. One contains O/S files and the other contains database files. I'm a bit concerned that the O/S disk may fail some day (the disks/machine has run 24X7 for the past 2 years). I have Enough room to put all files on one disk. I've read from the documentation that is only possible to do O/S mirroring at install time. Is that true? I would like to move all files from the one disk to the other, and then start mirroring the disks, without re-installing the O/S. Is that possible? Also, how "good" is the RH mirroring (problems, bugs, etc.)? Another option I'm considering is to leave things alone and buy a 3rd disk. Then do a "dd" from the O/S disk to the new disk, nightly. Will that allow the 3rd disk to be bootable? Somehow I would have to tell Lilo about the 3rd disk possibly being a boot disk. Is that possible? I'm running RH 9. Any help appreciated. -Jim -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
