Volume Encryption always on?

[kuruption]

Building a new NAS box w/ FreeNAS-8.3.1-RELEASE-p2-x64 (r12686+b770da6_dirty), creating a new volume inside the WebUI and watching the log file, when I see this...

Note: I didn't select encryption when creating the volume.... ;)
So what's up with this? I checked to see what geli thought in the command line:

# geli status da8p1.eli​

Name Status Components​

da8p1.eli ACTIVE da8p1​

# geli list da8p1.eli​

Geom name: da8p1.eli​

State: ACTIVE​

EncryptionAlgorithm: AES-XTS​

KeyLength: 256​

Crypto: software​

Flags: ONETIME, W-DETACH, W-OPEN​

Providers:​

1. Name: da8p1.eli​

Mediasize: 2147483648 (2.0G)​

Sectorsize: 4096​

Mode: r1w1e0​

Consumers:​

1. Name: da8p1​

Mediasize: 2147483648 (2.0G)​

Sectorsize: 512​

Stripesize: 4096​

Stripeoffset: 0​

Mode: r1w1e1​

So I destroyed the volume, and tried to create it again... making sure I didn't click the encryption checkbox this time (just to be sure), and the same thing happens.
Is this a bug? Or something that's expected? Because it seems awfully odd that GELI is telling me there's encryption on these slices when I don't want it.

I'm being dumb, I think... I just noticed the p1 vs p2... and read something about cache devices? So the cache device is encrypted?

Hi kuruption,

The encrypted items are actually the swap partitions that FreeNAS creates on each data drive. It's normal, nothing to worry about.
