After installation you can:
: #1 - Add new hard drive (two for RAID5)
: #2 - Create failed disk RAID1 or RAID5
: #3 - Create file system on RAID1 or RAID5
: #4 - Boot from rescue disk (must have RAID kernel on it)
: #5 - Copy old non-RAID to new RAID using afio or cpio
: #6 - Reboot to new RAID (change fstab and rdev your kernel)
: #7 - raidhotadd old disk
Perhaps I live on the wild side, but I don't even boot from a
rescue disk.
I created the file system on the RAID1, cp -a'd the data over,
modified the /new/etc/fstab, whipped up my /mnt/boot1/etc/lilo.conf
and /mnt/boot2/etc/lilo.confs (/mnt/boot1 and /mnt/boot2 are
non-RAIDed, 16MB ext2fs partitions I use to boot from), then booted
straight to the new, degraded raid. THEN I performed your step 7 ..
.. of course, one of these days I'll botch up the lilo.conf
and be unable to boot, but hey, that's half the fun of playing with
this stuff. =)
