Hi,

You can just run
Quote:

mdadm -A /dev/md122
and it will become active again.

If you get this error on every boot, you probably need to edit your /etc/mdadm/mdadm.conf file, try appending output of
Quote:

mdadm --examine --scan
to the end of your mdadm.conf

thank you for help.
Unfortunately I tried that before and It did not help - so I have to stop and create the new one bear in mind to lost all data of course.
