Is it possible to reshape my /dev/md0 raid5 into raid6? I found the following recipe in the docs: mdadm --create /dev/md0 -l6 -n4 /dev/sdb1 /dev/sdc1 /dev/sdd1 missing I have 9 disks in my raid5, would i then do: [1] mdadm --create /dev/md0 -l6 -n10 /dev/sda /dev/sdb ... missing i.e. only the first 9 drives and then hot add a new device to get it to reshape and add the extra parity to all drives? mdadm --add /dev/md0 /dev/sdk ? I would guess command [1] would give problems as md0 is an active array will it work if i --stop the array first so that i can reshape to raid6? I couldn't really find much information on this, some say it is impossible without recreating the array? (So i ask here first before i try, as I dont want to risk my data, even though I have backups of the important data) Any advice would be nice /Michael Ole Olsen
