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

I don't know that it matters but I use --raid-devices instead of disks. mdadm --grow /dev/md2 --level=6 --raid-devices=6 --backup-file=/home/md.backup

Note: I'm in hour 33 with 1000 min remaining at 65% of a 7->8 Raid6 ... CPU 60-70% idle and only 7-10mb/s (speed_min set to 15mb/s) wish I could speed it up (started at 13mb/s).
