F20: system does not resume from hibernate

[Ranjan Maitra]

Hello,

I have been putting my F20 laptop to hibernate using systemctl
hibernate: everything works fine, except that starting up has usually
ended up doing a reboot and going to the login screen.

What am I doing wrong? Note that I am using a commandline interface in
exactly the same manner as F19 two days ago.

Any suggestions? This (hibernate) is an important feature for me!

Many thanks for any help you are able to give!

Best wishes,
Ranjan

Make sure you have enough swap space. By default the installer may not create enough because it doesn't use the hibernation calculation, which is roughly 2x memory for a laptop with 4GB - 16GB of RAM.

My box (8 GB mem,  20Gb swap space) does  no resume after hibernating,
but boots normally (https://bugzilla.redhat.com/show_bug.cgi?id=948177)

Yes, I have enough swap (16 GB, 8 GB memory). I had no problems
with F19 or with systems upgraded from F19.

According to this bug report, I need to add

resume=<swapdevice>

to the grub line.

According to suomi, I need to add:

resume=UUID=ec23581a-b819-4f21-af67-87802223e983

Which one, and if the latter where do I get this UUID number from?

Many thanks!

You can also use "resume=/dev/sd<xy>" (your swap partition). That's more
simple :-)

Absolutely, thanks!

But where do I find this value? I can't see it on my df:

Filesystem     Type      Size  Used Avail Use% Mounted on
/dev/root      ext4      9.5G  3.3G  5.8G  37% /
devtmpfs       devtmpfs  3.7G     0  3.7G   0% /dev
tmpfs          tmpfs     3.7G  148K  3.7G   1% /dev/shm
tmpfs          tmpfs     3.7G  604K  3.7G   1% /run
tmpfs          tmpfs     3.7G     0  3.7G   0% /sys/fs/cgroup
tmpfs          tmpfs     3.7G   20K  3.7G   1% /tmp
/dev/sda1      ext4      477M   80M  369M  18% /boot
/dev/sda5      ext4      969M  2.3M  900M   1% /usr/local

/dev/sda7      ext4      3.8G  527M  3.1G  15% /var

However, free yields:

Mem:       7732364    1253864    6478500       2544      37264
334996 -/+ buffers/cache:     881604    6850760
Swap:     16383996          0   16383996

and I did set it up using anaconda.

Many thanks again!

Answering my own question: after some searching,

swapon -s

gives me the mount point.

Will now test out the hibernation.

Thanks!

lsblk,sudo blkid are also good to remember.

F20: system does not resume from hibernate (SOLVED!)

and the resume works. Unfortunate why I had to go through this circus
on F20. F19 had no issues, also none with F20 upgraded from F19.

Allegedly, on or about 19 December 2013, Ranjan Maitra sent:

I have to ask:  We should *we* have to do that?  Surely, the
*installation* *routine* should be setting that up.

I'm confused whether this requires a kernel parameter to work correctly, or if it's something systemd should be managing better, and the resume= parameter is deprecated under systemd.

If it requires this kernel parameter, it's anaconda that should write out the necessary parameter to /etc/default/grub so that it ends up in the grub.cfg. So a bug would need to be filed against anaconda.

However, this may be the domain of systemd recently.

Did you insert the RESUME disk (i.e. your swap partition) into your 
linux statement in the grub menu?

e,g,
    linux	/vmlinuz-3.11.9-100.fc18.x86_64 
root=UUID=722d9f6f-867b-4c04-a340-ba3caa23c42f ro rd.md=0 rd.lvm=0 
rd.dm=0 vconsole.keymap=sg  rd.luks=0 LANG=en_US.UTF-8 
resume=UUID=ec23581a-b819-4f21-af67-87802223e983
