Follow-up Comment #9, bug #39527 (project grub):
In my case the command list works as i described, even without the
grub2-install after removing the disk. I don't understand why it's logical
that the grow -n 2 and fails if executed right after the grow -n 1 -f command.
It's an administrative change of the number of disks in the array, in my
opnion that can be changed anytime.
This is the command log, i only modified the cat /proc/mdstat output to
include only md0 instead of all 7 array's to make the output easier to read.
