[Bug 1567085] Re: LUKS swap partition destroyed upon reboot in 15.10 and 16.04

Fri May 13 15:19:54 UTC 2016

I have switched from using UUIDs to /dev paths in cryptsetup and now
that problem is gone, however, the swap STILL won't work. Now I have
this:

$ journalctl -b | grep -i crypt

Running swapon /dev/mapper/sda2_crypt manually later enables the swap.

Title:
  LUKS swap partition destroyed upon reboot in 15.10 and 16.04

Status in systemd package in Ubuntu:
  Incomplete

Bug description:
  Usually on every reboot, sometimes every other, the LUKS encrypted
  swap partition is being destroyed. blkid shows no UUID for the
  partition, cryptsetup doesn't recognize it as a LUKS partition. This
  is logged:

  Tra 06 23:05:41 deltalabs systemd[1]: dev-disk-by\x2duuid-9e972bb6\x2df6dc\x2d4e64\x2d8976\x2d2df54bd076f7.device: Job dev-disk-by\x2duuid-9e972bb6\x2df6dc\x2d4e64\x2d8976\x2d2df54bd076f7.device/start tim

  Tra 06 23:05:41 deltalabs systemd[1]: Dependency failed for Swap.
  Tra 06 23:05:41 deltalabs systemd[1]: Dependency failed for Encrypted Volumes.

  The disk layout is as follows:

  Number  Start   End     Size    Type     File system  Flags
   1      1049kB  1024MB  1023MB  primary  ext4         boot
   2      1024MB  6024MB  5000MB  primary
   3      6024MB  406GB   400GB   primary
   4      406GB   430GB   24,0GB  primary

  #2 is LUKS swap and #3 is LUKS root, which obviously gets decrypted
  and mounted okay. This started happening after an update in 15.10 few
  weeks ago and aparently continues in 16.04 beta 2.
