It would be great to have full disk encryption support. USB pen drive with encryption key could be used to unlock device upon boot up. Is it planned?
I am looking for a NAS solution that supports btrfs with encryption (dm-crypt/LUKS). I consider encryption a must. As I am running my test installation of Rockstor in a VM with the system disk as a virtual image on an encrypted drive of the host (Windows 2008 R2 with bitlocker) and expect to continue running it as a VM I don´t care too much whether the key is on USB or somewhere else, but imho an USB key accessed during boot is definitely a good choice. Obviously I could also encrypt the drive using the host operating system and use a virtual image for the real data, but that would prevent migration to real hardware or a different host (I plan to migrate most of my stuff to Linux over time).
I am also willing to experiment with a drive I encrypt and mount on the command line, but at present I have no clue how to make this known to Rockstor to add shares etc. Any insight on this could help getting me started, and I might be willing to test and enhance documentation in return…
