Hi Neil, Same result with the latest commit after a reboot. Maybe the problem comes from the fact that I first try to assemble the array without providing a backup file ? For reference I did the following : mdadm --create /dev/md0 -l 5 -n 3 /dev/sd[bdf]1 mdadm --add /dev/md0 /dev/sde1 [wait for the raid 5 to rebuild] mdadm --grow /dev/md0 --backup-file backup -l 6 -n 4 [wait a few hours] reboot mdadm --assemble /dev/md0 /dev/sd[bdef]1 mdadm --assemble /dev/md0 /dev/sd[bdef]1 --backup-file backup Any other output you'd need ?
