Subject: Re: [PATCH] mdadm: fix reshape from RAID5 to RAID6 with backup file
Date: Tue, 16 Mar 2021 15:54:22 +0100	[thread overview]
Message-ID: <eb0060d3-756d-c6f9-66d7-bcd7b0468bf7@linux.intel.com> (raw)
In-Reply-To: <84ed6e32-3b69-f13d-b1b8-33166c92e5ab@trained-monkey.org>

Hello Nigel,

Blame told us, that yours patch introduce regression in following
scenario:

#mdadm -CR imsm0 -e imsm -n4 /dev/nvme[0125]n1
#mdadm -CR volume -l0 --chunk 64 --raid-devices=1 /dev/nvme0n1 --force
#mdadm -G /dev/md/imsm0 -n2

At the end of reshape, level doesn't back to RAID0.
Could you look into it?
Let me know, if you need support.

Thanks,
Mariusz
