Re: Converting RAID5 to RAID6 and other shape changing in md/raid

21 August 2009, 07:35 UTC


Following your instructions, i upgraded to mdadm, but this command looks not to work

mdadm --grow /dev/md0 --level=6 --raid-disk=6 madam: /dev/md0: Cannot reshape array without increasing size (yet).

I wanted to convert a 5-disk RAID5 to 6-disk RAID6.

If i use this command below, there is another error: mdadm --grow /dev/md0 --level=6 --raid-disk=6 --size=max madam: can change at most one of size, raiddisks, bitmap, and layout.

Could you give some instructions? Thanks.
