Date: Wed, 12 Jan 2011 04:19:30 +0000 Message-ID: <4D2D2BD2.7000601@anonymous.org.uk> Mime-Version: 1.0 Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: 7bit Return-path: Sender: linux-raid-owner@vger.kernel.org To: Linux RAID List-Id: linux-raid.ids I've just started reshaping a RAID-5 to a RAID-6. I had meant to increase the number of drives too, so avoiding using the backup file all the way through. Unfortunately I forgot to specify that, so it's going rather slowly. I said: mdadm /dev/md1 --grow --level=6 --backup-file=/some/where/else where md1 had 3 active and 2 spare devices. It's now reshaping itself to RAID-6 with 4 active and 1 spare. What I meant was mdadm /dev/md1 --grow --level=6 --raid-disks=5 --backup-file=... Can I cancel reshape that's currently running, and using the backup file that's actually on another (RAID-1) array on three of the same drives, and running at ~7MB/s, and try again? Cheers, John.
