My current LVM configuration: I have two physical volumes (pv):
256 GB of
1 TB of
HDD. These volumes are used by different volume groups (vg):
SSDvg has logical volumes which are mount where speed is required
HDDvg for all other places
Now I want to perform full disk encryption, but all tutorials (e.g. this one) uses only one volume group to create logical volumes, so I have doubts that I will not be able to split my drives to "fast" and "common" ("fast" from
SSD, "common" from
HDD) groups and mount "fast" group where needed.
So my question is: how to perform full disk encryption, but keep two volume groups in LVM?
