Subject: Cancel reshape?
Date: Wed, 12 Jan 2011 04:19:30 +0000 [thread overview]
Message-ID: <4D2D2BD2.7000601@anonymous.org.uk> (raw)
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.
