Encrypting data written to an LVM snapshot with a different key
I have the following requirements:
- I have an LVM volume
A
, encrypted with keyK1
using LUKS. - I need to make a copy-on-write snapshot of
A
such that
- Writes to
A
will continue to be encrypted underK1
- Writes to the snapshot will be encrypted under
K2
, which is different fromK1
.
- Writes to
The use case is to allow the snapshot to be securely deleted by deleting the encryption key.
Is this possible?
