Hi, On Ubuntu 14.04: kpartx version 0.4.9-3ubuntu7.2 has interesting behavior. kpartx from version 0.5.0 built from source misbehaves identically. The following works as expected: cd / kpartx -a mnt/path/to/disk.img kpartx -d mnt/path/to/disk.img However, if I use absolute paths, instead of relative paths, -a will succeed, and -d will unexpectedly silently have no effect. kpartx -a /mnt/path/to/disk.img kpartx -d /mnt/path/to/disk.img # silently has no effect In this case, to delete the partition mappings, I need to: kpartx -d /dev/loop0 losetup -d /dev/loop0 Further investigation revealed that kpartx is unexpectedly confused by different files that happen to have the same name: cd /mnt/path/to kpartx -a disk.img # succeeds, as expected cd .. kpartx -d to/disk.img # silently has no effect cd /tmp touch disk.img kpartx -d disk.img # unexpectedly unmaps /mnt/path/to/disk.img and detaches /dev/loop0 Cheers, Parke -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
