well, I prefer to encrypt LV itself, and I'm trying the same
what worked always with my "regular" LVs, yet - "cache pools
LVs" fail to encrypt with: Command failed with code 22.

question I'd like to ask is: how to LUKS encrypt cache
pool LV ?
many thanks.
L.
In general without being any expert here you will need to
encrypt the origin device (PV) on which it resides and
likely also the PV of the cache pool itself. It's no
different from any other volume you would use.
You can allow LUKS to pass-through discards if you open
the volume with --allow-discards on the cryptsetup prompt
(command).
In case you have an SSD underneath. It was said that the
cache itself does not utilize discards just yet, but that
it was in the planning.
