I have a partition lying on a software raid device, /dev/md4
On boot, fsck fails and the partiton cannot be mounted. Trying to fsck manually, I get an error:
sudo fsck /dev/md4 fsck from util-linux-ng 2.17.2 e2fsck 1.41.11 (14-Mar-2010) fsck.ext4: Device or resource busy while trying to open /dev/md4 Filesystem mounted or opened exclusively by another program?
sudo lsof /dev/md4 gives no output...
Is there a way to force a fsck on an md device ?
