Thanks to Jakob I have my data back. <phew>. Just for the record I made a raidtab with the following:- raiddev /dev/md5 raid-level 5 nr-raid-disks 3 chunk-size 64k persistent-superblock 1 nr-spare-disks 0 device /dev/sda2 raid-disk 0 device /dev/sdb2 raid-disk 1 device /dev/sdc2 raid-disk 2 and ran "raidstart /dev/md5". Looking in the syslog showed that the raiddev was wrong - needed to be /dev/md2. So I corrected that and ran "mkraid --really-force /dev/md2" The array now corrected I was able to mount the root filesystem and copy the original raidtab to my repair disk and run mkraid on the other partitions. I now have my data. Finally, what could have caused this? I'm pretty confident about the hardware (I've not replaced anything yet) - could a power outage have broken my arrays? many thanks nick. - 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
