>From following http://marc.theaimsgroup.com/?l=linux-raid&m=101435499712822&w=2 message, i understand this is possible by 1) setting a up a degraded raid array 2 copying at filesystem level files from normal partitions to raid partitions 3) mouting raid partitions in place normal partitions 4) restoring raid array to normal state However, the previous mail mention a mdctl tool that is not present in my Linux distribution (mdk 8.2). I suppose this is just another raid management tool, and that i can safely use mkraid from raidtools instead, provided i set my normal partitions as "failed-disk" in /etc/raidtab, as explained in http://unthought.net/Software-RAID.HOWTO/Software-RAID.HOWTO-4.html#ss4.4 Am i correct here ? -- Guillaume Rousse <rousse@ccr.jussieu.fr> GPG key http://lis.snv.jussieu.fr/~rousse/gpgkey.html - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
