Moving a boot partition to a more stable format
Hi,
I built a debian server a while ago, with all of the main partitions across an LVM volume, which is then mirrored across two drives using kernel RAID1. I left swap out and effectively stripe them by setting their priority to 1 in /etc/fstab. However the boot partition still only exists on one of the disks (/dev/sda1). I would like to mirror that as well so if either drive goes down, the system can boot regardless. I distantly remember being warned off creating them as a RAID1, but can't remember the exact reason. How's the best way of achieving want I want and does anyone have any good up-to-date instructions? I've cut and pasted the file list at the bottom,
On a side note, if I remove one of the disks from a raid 1 configuration, if I then mount the partitions, are they safely readable as with any ordinary ext3 partition for instance?
Thanks for any help,
James
