Hello,
I have a Synology NAS with two 3Tb disks in RAID1 (sda+sdb).
The output of /proc/mdstat is:
Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4]
md2 : active raid1 sda3[0] sdb3[1]
2925544256 blocks super 1.2 [2/2] [UU]
md1 : active raid1 sdb2[1] sda2[0]
2097088 blocks [10/2] [UU________]
md0 : active raid1 sdb1[1] sda1[0]
2490176 blocks [10/2] [UU________]
unused devices: <none>
I have added another two 3Tb disks (sdc and sdd).
I would like if possible to convert the raid1 to raid10.
I have seen guides on google on how to do this either by:
Creating a RAID10 with the two new disks and specifying two disks as
missing. Remove one old disk, sync and then add the fourth and final
disk; OR
Another method outlined here:
http://www.linuxquestions.org/questions/linux-server-73/convert-raid-1-system-into-raid-1-0-a-557471/
My issue is that I actually have md0 md1 and md2 (presumably because
there are partitions which hold the OS for the NAS).
Can I still do this grow operation?
Is anyone able to help me through this please?
Thanks in advance
