[Bug 1968805] Re: Hibernation fails when an additional swapfile is added due to priority mismatch
Performing verification for Bionic. Bionic seems to hibernate okay on both Xen and KVM based instances, so I tested both t2.medium and c5.large instance types. Each had 20gb of storage, with advanced > enable encryption > yes. I also made sure to enable Advanced settings > Stop State (Hibernation) Support > Enabled. I started two sets of instances, one with 1.0.0-0ubuntu4~18.04.5 from -updates, and the other with 1.0.0-0ubuntu4~18.04.6 from -proposed. After leaving each instance for a few minutes to finish setting up hibinit-agent.service, I pressed Instance State > Hibernate. Both instances hibernated successfully, and within 30 seconds of pressing the hibernate button. I then started both instances, and ssh'd in. My screen sessions were both active, so hibernation was successful. The base case of no additional swapfile configured results in correct hibernation for both -updates and -proposed packages. I then followed the below steps, and added an additional swapfile to each instance. $ sudo fallocate -l 4G /swapfile $ sudo dd if=/dev/zero of=/swapfile bs=1024 count=4194304 $ sudo chmod 600 /swapfile $ sudo mkswap /swapfile $ sudo swapon /swapfile $ echo "/swapfile swap swap defaults 0 0" | sudo tee -a /etc/fstab $ swapon --show NAME TYPE SIZE USED PRIO /swapfile file 4G 0B -2 I went back to the console and pressed Instance State > Hibernate. This time, both instances hibernated successfully, and completed within 30 seconds of pressing the hibernate button. Bionic has a different behaviour to that of Focal and onward, where the -updates package would stay running, and be force stopped 20 minutes later. On Bionic, both hibernate successfully. I then started both instances. Both instances came up correctly, and I could ssh in. But my screen sessions were missing, and journalctl showed this was a fresh boot for both instances. It seems Bionic has issues resuming from hibernation when there is an additional swapfile set, but most users do not notice it, because the instance comes up and starts correctly, as if hibernation had been successful. Journalctl in both suggests that it wasn't aware that it was hibernated in the first place as no attempt to resume was made, so perhaps we are setting the resume= variable on the kernel command line wrong. I checked, and Bionic sets it as: resume_offset=401408 resume=PARTUUID=80f6dacd-01 I checked the offsets manually with $ findmnt -no PARTUUID -T /swap-hibinit 80f6dacd-01 $ sudo filefrag -v /swap-hibinit Filesystem type is: ef53 File size of /swap-hibinit is 4194304000 (1024000 blocks of 4096 bytes) ext: logical_offset:physical_offset: length: expected: flags: 0:0.. 0: 401408..401408: 1: everything matched. Very strange. It should have resumed... Regardless of the outcome, I checked journalctl of the previous boot, and for the instance with -updates enabled, we see: Jun 03 05:04:02 ip-172-31-26-1 systemd-logind[1108]: Suspend key pressed.

The changes in this SRU are still beneficial and needed, and worth the regression risk even though there is no behavioural change to the user with the package in -proposed versus the package in -updates. It also keeps the code in ec2-hibinit-agent in sync with focal and onward regards to changes. I think we should look into the hibernation issue with Bionic in a separate bug, and track it there, and keep this bug about making sure /swap-hibinit is enabled with

[Bug 1968805] Re: Hibernation fails when an additional swapfile is added due to priority mismatch
The fix has now been merged upstream with:
commit a2303d269610a6e7415c5045766da605eaa7e30f
From: Matthew Ruffell
Date: Wed, 20 Apr 2022 15:59:25 +1200
Subject: Swapon with maximum priority before hibernation
Link:
https://github.com/aws/amazon-ec2-hibinit-agent/commit/a2303d269610a6e7415c5045766da605eaa7e30f
** Description changed:
[Impact]
It is not uncommon for users to add a swapfile to their AWS instance, in
case they run short of memory. For users that optionally enable
Hibernation support, the swapfile generated by ec2-hibinit-agent, /swap-
hibinit, needs to always be the highest priority when it comes to
suspend the system, since ec2-hibinit-agent sets up /swap-hibinit to be
the correct way to suspend and resume via the resume=UUID= and
resume_offeset= kernel command line parameters.
ec2-hibinit-agent keeps /swap-hibinit swapoff during normal instance
use, and right before Hibernation occurs, /etc/acpi/actions/sleep.sh
swapon /swap-hibinit, and calls systemctl hibernate:
do_hibernate() {
if [ -d /run/systemd/system ]; then
systemctl hibernate
case "$2" in
SBTN)
swapon /swap-hibinit && do_hibernate
Something changed between 18.04 and 20.04, such that new swapfiles are
added with a lower priority than the previous swapfile when they are
swapon:
On Focal and later, we see behaviour like if we simply swapon /swap-hibinit
generated by ec2-hibinit-agent, we
see it is -2:
$ sudo swapon /swap-hibinit
$ swapon --show
NAME TYPE SIZE USED PRIO
/swap-hibinit file 3.9G 0B -2
Turning it off:
$ sudo swapoff /swap-hibinit
$ swapon --show
NAME TYPE SIZE USED PRIO
Lets add /swapfile in:
$ sudo swapon /swapfile
$ swapon --show
NAME TYPE SIZE USED PRIO
/swapfile file 4G 0B -2
Now we enable /swap-hibinit again, and see it is -3:
$ sudo swapon /swap-hibinit
$ swapon --show
NAME TYPE SIZE USED PRIO
/swapfile file 4G 0B -2
/swap-hibinit file 3.9G 0B -3
Lets add in another swapfile, /swapfile-second, and we see -2, -3, -4:
$ sudo swapon /swapfile-second
$ swapon --show
NAME TYPE SIZE USED PRIO
/swapfilefile 4G 0B -2
/swap-hibinitfile 3.9G 0B -3
/swapfile-second file 4G 0B -4
What happens is that if we have a swapfile, say, /swapfile at default
priority -2, when we go to hibernate, the swapon in
/etc/acpi/actions/sleep.sh will set the priority of /swap-hibinit to -3.
systemd / the kernel will then select the highest priority swapfile to
hibernate to, in this case /swapfile, which is NOT setup for resume= or
resume_offset= on the kernel command line, and hibernation will fail.
Apr 11 21:08:15 ip-172-31-84-225 kernel: [ 240.990073] Adding 4095996k
swap on /swap-hibinit. Priority:-3 extents:6 across:4644860k SSFS
This leaves the instance in the "Stopping" state on the EC2 console
until it hits the 20 minute timeout, at which point it is force stopped.
The fix is to set the priority when we swapon /swap-hibinit to something
higher than any other swapfile, to ensure we hibernate to /swap-hibinit.
[Testcase]
From the EC2 console, select "Launch Instance".
Create a:
- t2.medium
- Ubuntu 20.04, 21.04 or 22.04
- 20gb storage space, advanced > enable encryption > yes.
- Advanced settings > Stop State (Hibernation) Support > Enabled
On boot wait for ec2-hibinit-agent to complete hibinit-agent.service,
and see that /swap-hibinit is created, and swapoff.
$ ll /swap-hibinit
Add a swapfile, and switch it on:
$ sudo fallocate -l 4G /swapfile
$ sudo dd if=/dev/zero of=/swapfile bs=1024 count=4194304
$ sudo chmod 600 /swapfile
$ sudo mkswap /swapfile
$ sudo swapon /swapfile
$ echo "/swapfile swap swap defaults 0 0" | sudo tee -a /etc/fstab
$ swapon --show
NAME TYPE SIZE USED PRIO
/swapfile file 4G 0B -2
Go back to EC2 console, "Instance State" > "Hibernate".
You will see this in journalctl:
Mar 15 11:41:54 ip-172-31-27-108 kernel: [ 520.121761] Adding 16095656k swap
on /swap-hibinit. Priority:-3 extents:13 across:17611176k SSFS
Mar 15 11:41:54 ip-172-31-27-108 root: ACPI action undefined: LNXSLPBN:00
and the instance will not hibernate. EC2 console will report "Stopping"
for 20 minutes until it times out and is force stopped.
If you enable the following ppa and install the test ec2-hibinit-agent
package:
https://launchpad.net/~mruffell/+archive/ubuntu/sf331069-test
Hibernation should succeed within a minute or two.
[Where problems could occur]
This change will only affect users of instances where Hibernation has
been explicitly enabled, either from the EC2 instance launch advanced
settings, or via the "--hibernation-options Configured=true" parameter
to the "aws ec2" command. For all other users, including those
