@sea_striker First off welcome to the Rockstor community.

Yes we don’t currently support LUKS but I intend to get stuck into this one shortly and will mark all development against our existing issue opened for this very feature:

A little more ground work is necessary but I would also like to make good on some previous promises before I embark on this one, but it is definitely getting closer and some ground work has already been put in place.

Sounds good, LUKS support would be a great feature overall, and a killer feature for me personally.

I’ve read about the work that has been put in this year and it looks like a significant portion of the work has been done. In fact I was working on this today because I thought that RockStor might support LUKS if I handled everything up to presenting a device in /dev/mapper, but that is not the case. It appears that there are some conflicts to be handled before that can be done cleanly, however not knowing the codebase, I can’t really comment on that.

As an intermediate step however, is it possible to add support for devices added into /dev/mapper?

In any event, it looks great, I’m just waiting for LUKS before I switch over my main storage.
