Please can you further define what you mean by 'it can become a problem to boot' ? Generally this is resolved by having a mbr and boot partition on each of your mirrored drives so that whichever you use to boot has the pertinent information to boot the kernel and construct the raid array. If you have raid 5 with 3 disks you'd have a 3 drive mirror partition on each disk and a raid 5 set across all three too. I'm not a guru on this and can't provide much knowledge past the theory and high level ;-) Simon On 20 May 2011, at 07:55, Paul van der Vlis <paul@xxxxxxxxxxxxx> wrote: > Hello, > > I use software raid (mdadm).
