Reboot is allowed even if mdadm is resyncing RAID members

When managing RAID with mdadm tool under GNU/Linux, you may wonder if a restart is possible when resync of members is in progress.

The answer is: YES, it is possible.

After a reboot, the system will continue resyncing members until the end, whatever the count of restart.
It is an useful information when you want continue installing/configuring your OS without having to wait until the end of resync.
