Unlike lvm, the=20 kernel can pickup md/RAID parameters from its command line and can boot=20 into it directly, so that's how I have it arranged, /boot on RAID-1 as=20 that's all the RAID grub can handle, root and rootbak, along with the=20 physical volume for my LVM for everything else redundancy critical on=20 partitioned RAID-6, and 4-way striped swap and RAID-0 for caches (ccache,= =20 the Gentoo tree, /usr/src/linux/) that are speed but not redundancy=20 critical. The root and rootbak partitions contain most of /usr and /var as well,=20 basically everything that gets touched by ebuilds and the package manager= =20 including its data, so it all stays in sync. If I were doing it over,=20 the only two things I'd do differently would be to have two rootbaks, so=20 if the system crashed while I was writing the one backup and neither it=20 nor the primary working root were functional, I could still boot the=20 other backup, and I'd create my RAID using at least 5 spindles/drives=20 (but go lower end on capacity per spindle), as writing to a 4-way RAID-6=20 is slowwwww. --=20 Duncan - List replies preferred.
