I've installed new Ubuntu 16.10 with LVM on LUKS using this instruction: (https://askubuntu.com/a/293029). But when I type swapon -s I get:

Filename                Type        Size    Used    Priority
/dev/dm-1                               partition   3145724 0   -1

UPD: Made the fresh install with standard options of encryption (erase disk, encrypt disk, use lvm). Swap still not working

  • Same issue in my case as well – Khamidulla Dec 13 '16 at 2:23

    The output you posted before the update shows you have a fully working swap partition of about 3gb, which remained unused at that moment... – dgonzalez Jan 6 '17 at 2:00

"Used 0" might be perfectly fine if you have plenty of RAM. In fact I have the same right now but sometimes when I use more memory things get swapped.

  • Now I use swap file instead of swap partition and it works – danielleontiev Jan 7 '17 at 1:44
