Solaris 11 swap encryption

edited Jul 9, 2014 1:05PM in Oracle Solaris System Administration (MOSC) 4 commentsAnswered ✓

Please, what the current status of swap encryption?

vfstab(4) says it suffices to use the "encrypted" option, but that's not quite the case, at least on Solaris 11.1.20.5.

If set the option, swap -lh doesn't list a swap device anymore.

In fact, /usr/sbin/swapadd script is rather strange: it doesn't even mention any ZFS operation.

These symptoms are similar to what was once described in Encrypted SWAP Device Just Disappeared In Solaris 11 EA - blog'o thnet

I was wondering if I manually set the encryption of rpool/swap it will be OK or will I cause a big problem?

Thanks in advance.

Howdy, Stranger!
