Re: LUKS layer / best practice

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



I recommend having LUKS be "under" LVM. the layers would be:
/dev/sda -> partition (/dev/sda1) -> LUKS (/dev/sda1_crypt) -> LVM physical
volume -> volume group -> logical volume -> filesystem

The layers described above are how the Ubuntu installer sets up an
encrypted LVM filesystem. As far as I know, TRIM is passed through LUKS and
the LVM layers if it's available in the hardware.

Sincerely,
Jason
