Cant umount degraded raid

    • Cant umount degraded raid


      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:

      Source Code

      1. root@HomeServer:~# mdadm --stop /dev/md127
      2. mdadm: Cannot get exclusive access to /dev/md127:Perhaps a running process, mounted filesystem or active volume group?
      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:

      Source Code

      1. root@HomeServer:~# lsof /dev/md127
      2. root@HomeServer:~# fuser -m /dev/md127
      can you help me to get the raid unmounted?

      thanks, alex!
