SOLVED About swap and encrypton

[hugovsky]

If I create an encrypted volume, I have 12 GB of swap(6x 1TB). If I reboot, the encrypted volume is locked and swap partitions don't show up. Is this normal?

Can you elaborate on what you mean when you say "swap partitions don't show up"?

The words "show up" is a little vague. ;)

 

[hugovsky]

Sorry… ;)

Umm... no comment.

Posting just to add this from gui. Swap was there when I created the pool. Disappeared after reboot.

This is normal - when a drive is encrypted, it is "locked" (and encryption is done at the per-drive level) against all access. You have to unlock it before ZFS can see it and the system can swap on it, assuming that it has a swap partition.

So, if I unlock the pool, the system should start using it? is this what your saying? Because that's not what I see. Do I have to enable swap manually? Freenas never uses it again. It stays like that.

Sorry for taking so long to reply. Been out of internet access.

No, it should start swapping once the drives are unlocked. Sounds like a bug! Please file a bug report. :) Thanks.

Done!

Issue #6833 created.

Bug was closed and marked with resolved but latest snapshot still shows same problem. Should I open another bug? Just posted at bug #6833

Seems ok with latest snapshot. After reboot and unlocking the volume, swap is on. Thanks!
