[Bug 66637] Re: After running mkswap, swap space is discarded, system fails to hibernate (invalid swap signature)
Maybe at some point the system should also detect corrupted swap partitions and mkswap-uuid them so that no system can lose its swap without the user being told of it. For now, if people use mkswap, it's because their swap was corrupted, often because of hibernation problems - the two issues are linked. -- After running mkswap, swap space is discarded, system fails to hibernate (invalid swap signature) https://bugs.launchpad.net/bugs/66637 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 66637] Re: After running mkswap, swap space is discarded, system fails to hibernate (invalid swap signature)
There is another alternative to solve the UUID problem, that is use the
mkswap-uuid program.
Look at these two locations:
* http://www.nabble.com/DRBL-1.8.0-15-(stable)-released-t4492611.html
* http://free.nchc.org.tw/drbl-core/old/src/
You need to compile it manually, but the whole process takes only
several minutes :-)
So here are the steps:
1. sudo apt-get install build-essential uuid-dev
2. mkdir ~/work ; cd ~/work
3. wget http://free.nchc.org.tw/drbl-core/old/src/mkswap-uuid-0.1.0-2.tar.bz2
4. tar -xjf mkswap-uuid-0.1.0-2.tar.bz2
5. cd mkswap-uuid
6. make sudo cp mkswap-uuid /usr/local/bin
After that you have the mkswap-uuid binary which you can use to
recreate the swap partition with desired UUID:
7. swap_device=/dev/name-of-swap-partition
8. swap_uuid=put-desired-swap-uuid-here
9. sudo swapoff ${swap_device}
10. sudo mkswap-uuid -U ${swap_uuid}
11. sudo swapon ${swap_device}
12. sudo blkid ${swap_device}
There.

[Bug 66637] Re: After running mkswap, swap space is discarded, system fails to hibernate (invalid swap signature)
I'm going to jump in on this. I'm seeing a different but related problem. I'm using Gutsy. I am working on bare metal restoration (http://www.charlescurley.com/Linux-Complete-Backup-and-Recovery- HOWTO.html). The least intrusive way for me to perform a bare metal restoration is to provide the UUID to mkswap when I create the swap partition(s) at restoration time. I cannot let mkswap generate the UUID and then edit fstab gracefully because fstab isn't on the disk where I can get at it at the time the restoration code deals with mkswap and the swap partitions. Also, there could be other code elsewhere that uses the old UUID. Reading this issue, I propose that mkswap accept a UUID and use it when preparing a swap partition. That would satisfy my requirement. In addition, mkswap should generate and assign a new UUID only if: * There is no valid UUID already on the partition, and * The caller does not provide a UUID as an argument to mkswap. Alternatively, is there a general purpose tool one can use to set the UUID after running mkswap? I predict that other bare metal restoration facilities like bacula will also hit this problem. -- After running mkswap, swap space is discarded, system fails to hibernate (invalid swap signature) https://bugs.launchpad.net/bugs/66637 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I can confirm this on Kubuntu Feisty: when I updated the initial kernel (the first update after the installation from the CD), not only the libata was gone and sdX reverted to hdX, but the swap UUID was changed, thus not being used anymore, and the hibernation failed!

I have been having the same problems: I recently installed Feisty in my laptop and it would grind to a halt, thrashing until I couldn't do anything. Suspend to disk failed. It took days until I did track the problem to the fact it was not using my swap partition because the uuid created in my /etc/fstab wasn't the same as in the physical partition. The swap partition's uuid would change unpredictably, and I had to adopt the notation /dev/hdaX in my /etc/fstab to actually be able to use my swap partition. see bug #67437 as well. -- After running mkswap, swap space is discarded, system fails to hibernate (invalid swap signature) https://bugs.launchpad.net/bugs/66637 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 66637] Re: After running mkswap, swap space is discarded, system fails to hibernate (invalid swap signature)
fwiw, I disagree with some of the recent marking of duplications of this bug. As Scott James Remnant states above, this bug is for dapper-edgy upgrades where people have run mkswap by hand. Many of the recent supposed duplications are from people running feisty who've never seen this problem before (such as me). I think what is happening in fesity is that a hibernate/resume is failing for some reason (or more likely, various reasons), leaving the user with a swap partition that swapon doesn't like (although I can't be sure of that because it seems to have stopped happening to me) and so correcting it by resetting their swap, but this of course requires that fstab and /etc/initramfs-tools/conf.d/resume be updated and this (please correct me if I'm wrong) is not documented. Perhaps mkswap could be patched to warn users that they will need to update these files, or it could be patched to retain the UUID (perhaps with an option to make a new one) -- After running mkswap, swap space is discarded, system fails to hibernate (invalid swap signature) https://bugs.launchpad.net/bugs/66637 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I changed my fstab nad resume entries to plain old /dev/sda5, I'll test it in a moment. -- After running mkswap, swap space is discarded, system fails to hibernate (invalid swap signature) https://launchpad.net/bugs/66637 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This is not an upgrade bug. If you have a bug that is only related to upgrading from dapper to edgy AND YOU HAVE NEVER RUN mkswap (ie. your machine failed to hibernate), then you have a DIFFERENT BUG. Please don't hijack this one. ** Summary changed: - After upgrade from dapper to edgy, swap space is discarded, system fails to hibernate (invalid swap signature) + After running mkswap, swap space is discarded, system fails to hibernate (invalid swap signature) -- After running mkswap, swap space is discarded, system fails to hibernate (invalid swap signature) https://launchpad.net/bugs/66637 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 66637] Re: After running mkswap, swap space is discarded, system fails to hibernate (invalid swap signature)
Scott, thanks for you reply. You seem to claim the following about this bug: 1) It appears not only after a dapper-edgy upgrade. 2) It appears only after running mkswap on your swap partition without changing fstab accordingly. You're right with the first point, this issue seems to be more general than I thought. Sorry for changing the subject. About the second point, though, I'm not so sure. I had the exact same problems described here without running anything manually (unless the swap parition is initialized in the automatic update). Also, please note that the bug submitter mentions an upgrade in his report, but not running mkswap. Please re-read the bug's history, and also note the number of duplicates. I could file another report, but that seems both grauitious and harmful given the above. -- After running mkswap, swap space is discarded, system fails to hibernate (invalid swap signature) https://launchpad.net/bugs/66637 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I've the same problem and was partially solved recreating swap partition and changing fstab + /etc/initramfs-tools/conf.d/resume I'm able to hibernate when Ubuntu is at GDM login screen but if I try to hibernate when gnome is active (session initiated) the hibernation fail, never resume, recovered only turning off and some times removing batteries. The are several file system problem after restarted.

[Bug 66637] Re: After running mkswap, swap space is discarded, system fails to hibernate (invalid swap signature)
To Scott: It happened to me just after the upgrade, and I do not remember having used manually mkswap before the breakage. Nevertheless, I have to say that the upgrade failed midway for me, and I had to recover the system via a quite convoluted live-cd / manual mount / chroot and apt-get magic, so maybe in the meantime something strange happened. What I know is that I first noticed the problem due to inability to suspend-to-disk (aka hibernate). -- After running mkswap, swap space is discarded, system fails to hibernate (invalid swap signature) https://launchpad.net/bugs/66637 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

It was confirmed that the reporter had run mkswap I dind't even KNOW that 'mkswap' command until reading about it here as being part of the solution! I definitely did not run mkswap, ever. In fact, it happened on my FRESH install of Edgy. First time it happened it could have been because of an upgrade. I experienced massive instability, didn;t know about this bug at the time so then did a fresh install of Edgy. (re- using an existing swap partition). Not sure if the problem persisted or appeared again later. Whatever the cause, it's bad. Perhaps do an active check during startup that swap space is indeed available and make noise if it doesn't. -- After running mkswap, swap space is discarded, system fails to hibernate (invalid swap signature) https://launchpad.net/bugs/66637 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
