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!
