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

I was wondering how to reduce the number of devices on a RAID-5 without having to buy extra devices for the move... and you just implemented it!

On Linux I performed a test with a RAID-5 of 4 LVM volumes, hosting an ext3 filesystem. After shrinking the filesystem, I reduce the array size with mdadm from the branch devel-3.1 then I reduce the number of devices to 3 and grow the filesystem. It works perfectly.

Thank you and congratulations for all your work.
