I created RAID1 with two discs, then i simulated failure of one of the discs. It was sdb1. I restared the VM with one disc working in RAID array. Then i added new fresh disc to add to this array but i can't do that because i got error (mdadm: Cannot get array info for /dev/md127) The new disc is already formated. How to add that new disc, everything that i tried doesn't work.
i have one problem.
