[ILUG] Booting a broken raid array

[ILUG] Booting a broken raid array

there's many different schools of thought on this, and i'm sure others
will have other ideas, but here's what i do:

- buy an ide/sata -> compact flash adapter

- buy a 1gb compact flash card, put it in the adapter, connect up to
motherboard as disk0 (i.e. primary master on ide, sata0 on sata)

- add ide/sata/scsi disks as needed for main filesystem & swap

- partition as follows:

  - /boot goes onto the compact flash card, set as the booting device
in the bios
  - create a slice of swap on each of the disks (say 500MB - 1GB each)
at the start of the disk
  - fill the rest of the disc with a software raid partition
  - repeat for additional disks
  - build desired raid level MD device on the partitions
  - put a single LVM volume on top of that (for future expansion)
