OS: EL6 - sometimes I use
kpartx -a /mnt/.../lvdisk.img
to map the partitions and mount them via
After using the disk (unmounting it) I noticed that
detaching such mapping via kpartx -d does not result
in freeing up the loop devices. Results: System reboots
shows that the filesystem where lvdisk.img is located
can't be unmounted.
lsof, fuser, ps does not show any usage. Even removing the
device node via
dmsetup remove /dev/mapper/loop0pX
does not help. Trying to unmount the underlying filesystem
still shows /mnt: device is busy.
Any other suggestions would be greatly appreciated!
