Hi there,
lately I had the idea of setting up an external storage for a small cluster.
I asked myself if I could encrypt the storage? So the question is:
Is LUKS cluster save in the following way?
+-----------+ +-----------+
|Linux box 1| |Linux box 2| both LUKSOpen the HDD independently evtly
+-----+-----+ +-----+-----+ with different keys
\ / both mount the OCFS2 filesystem on success
\ /
\ /
firewire \ /
or scsi \ /
or SAS +--+---+--+
| OCFS2 |
| on |
| LUKS |
| on |
| HDD |
+---------+
I'm not sure if LUKS writes something to the header (or elsewhere on the storage) on a successful LUKSOpen.
Thanks an best wishes
Lars
