If I mount a simple loop device,
give me the devices opened.
Is something similar possible with
dmsetup is useful for anything device mapper related. For Example:
[root@localhost]~# dmsetup ls --target crypt luks-90dc732d-e183-4948-951e-c32f3f11b305 (253, 0) [root@localhost]~#
I just looked for the same thing, a list of my luks partitions, though I wanted a mapping to the physical /dev/sdX devices.
I found a solution for that here: https://bbs.archlinux.org/viewtopic.php?id=164798
