Re: Encrypted swap partition no longer encrypted

Hi,

For encrypted swap you can put ".eli" behind the device name in fstab.

So change "/dev/ada0p2" to "/dev/ada0p2.eli" in the new fstab and reboot.
NB: after encryption is enabled the device is not available as dumpdev anymore.

I don't know what caused the change for you.

Regards,
Ronald.
