Subject: Problem converting from raid5 to raid6
Date: Sat, 20 Mar 2010 20:01:07 -0700	[thread overview]
Message-ID: <20100321030107.GA18586@csy.ca> (raw)

Hello all,

I am trying to convert a 5 disk raid5 array to a 6 disk
raid6 but am having no luck. I first added the 6th disk as
a spare then
mdadm --grow /dev/md3 --level 6
mdadm level of /dev/md3 changed to raid6
mdadm: /dev/md3: Something wrong - reshape aborted
mdadm: aborting level change

dmesg doesn't show an error and neither does mdadm beyond
"something wrong". Is this supported?

mdadm 3.1.1 Linux 2.6.32.8 x86_64.

Thanks,
Shane
