Hi,

is there a utility to determine whether a LUKS volume is currently
suspended and needs resuming (via LuksSuspend/LuksResume)?

If not, how can it be implemented without duplicating large parts of
cryptsetup functionality?

You can use dmsetup info <name>
(name is the same like in cryptsetup)

In script you can use it even simpler:
dmsetup -c -o suspended --noheadings info <name>

But I am quite surprised it is not in "cryptsetup status" output :)

I will add this info there in next version.

Thanks,
Milan
