Mjolnir, Ghost, Backup, etc

NOTE TO EVERYBODY WHO IS NOT ME: You can ignore this post. It's just random notes that I need somewhere safe. However, as of Dec 2006, it no longer applies, I use a modified version of SaraB.

Ghost really doesn't like my combo of SATA, IDE, LVM, and whatnot. To get the IDE (hdb) backup copied to the SATA (sda) I had to:
1. GHOST /FDSZ /IAL image /boot from hdb (Drive 4) to an image.
2. Put a partition on sdb (good thing it was empty)
3. Re-run ghost, copy image to sdb (not sda2 where it should be!)
4. Boot from CentOS install DVD with kernel command line:
linux rescue hdb=noprobe noexec=off noexec32=off
(took ~2 hours to find out the last two stop grub 0.95 from segfaulting on an install!)
5. mount up /dev/sda2 (destination) somewhere. Go into that directory and wipe it clean.
6. From that directory: dump -0 -f - /dev/sdb1 | restore -rf -
7. Relabel sdb1 so we don't have two /boot partitions!: tune2fs -Ljunk /dev/sdb1
8. unmount /dev/sda2
9. chroot /mnt/sysimage
10. grub --no-floppy
root (hd0,1)
setup (hd0) <== kept segfaulting here on SATA drive until noexec flags from above.
[Don't use grub-install that bombed too!]

OK, that's all the scraps of paper I can find. I really need to get a backup system running on this server before I migrate to it!
