again i got the same problem like in this already solved thread. last months it happend from time to time, but i could solve it by doing the discribed steps again.
Clean, degraded Raid (Mirror)
but today it doesnt work, because i cant umount the raid. i get this error-message:
of course i tried to umount the raid before without getting a error-message - but the raid is still mounted.
even these commands dont bring up a result:
can you help me to get the raid unmounted?
