[Bug 66637] Re: swap not being mounted on boot
** Changed in: Ubuntu Sourcepackagename: None => util-linux ** Summary changed: - swap not being mounted on boot + mkswap should re-use existing UUID or warn about changing it ** Description changed: - Binary package hint: initscripts - Just upgraded to edgy. The new UUID-based fstab seems to be causing me trouble. First, whereas my root (and Windows) partitions have stable UUIDs, the swap partition doesn't, so it fails to mount on reboot. Somewhat related I'm sure is the fact that hibernation doesn't work. When resuming, it both doesn't resume properly, and also leaves the swap partition without a valid signature (mkswap fixes.) -- mkswap should re-use existing UUID or warn about changing it https://launchpad.net/bugs/66637 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

THANKS A LOT. i try to figure out, what i have done wrong yesterday. first i did determine the UUID of the swap-device and did a mkswap on the symbolic link /dev/disk/by-uuid/ (i do not know, why i did so) and maybe that will not work?! again: thanks you very much for your step-by-step - instructions! -- swap not being mounted on boot 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: swap not being mounted on boot
amnesia: yes, i have done exactly this: - determined my swap-partition device with fdisk -l - got the right UUID of the swap-partition with vol_id - wrote RESUME=UUID= in /etc/initramfs-tools/conf.d/resume - wrote the right UUID into the /etc/fstab - then i had to correct the symlink to /dev/hda2 (in my case) in /dev/disk/by-uuid to the new one, that vol_id has told me - regenerated the initrd with update-initramfs -u, what finished without errors. but after the next reboot, the swap partition is not used because the UUID has changed again -- swap not being mounted on boot 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: swap not being mounted on boot
Upon upgrade from a clean dapper install to the released version of edgy, this problem occurs. Suspend work ed the first time but I can't resume, and now I have no swap. I can fix it by doing mkswap, and I plan to (as outlined in the steps above), but it would be nice if upgrading dapper users were not all burned by this. Also note: after booting without resume=..., if the swap partition contains a valid resume image *it is dangerous to resume from it*. If you do, the kernel will have a different picture of the filesystem and its buffers than exists on disk and *filesystem corruption may result* (see the swsusp2 FAQ). One hopes the kernel is smart enough to mark the resume partition as out-of-date to avoid this pitfall. -- swap not being mounted on boot 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: swap not being mounted on boot
thx for all the help, but for me it does not work. i did it as described and it updated the initramfs, but after every reboot the swap-partition has a different UUID. i switched back to the old-fashioned style and my swap partition will be used as /dev/hda2, but if anyone has hint for me, i will try und report. ben -- swap not being mounted on boot https://launchpad.net/bugs/66637 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

same problem herer aswell jens' solution worked for me too (mkswap, change to new UUID in fstab, edit resume file, update initramfs).

[Bug 66637] Re: swap not being mounted on boot
right, you end up with a hibernate image in your swap partition; and nothing restores that that's not corrupted though,you could just boot with resume= to restore it running "mkswap" by hand is what actually buggers you :) -- swap not being mounted on boot 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: swap not being mounted on boot
But anyway if conf.d/resume doesn't exist (that can happen), the computer will corrupt the swap when hibernating and the swap will not be used on reboot because it doesn't have a valid signature. To me that's a bug, a system with a swap partition should pass a 'resume=' parameter to the kernel so that it can use it as swap even if a swsusp image is stored. So please fix initramfs-tools to do that. I don't care for me, I fixed it anyway, but I'm sure there are other that would be happy if that is corrected. -- swap not being mounted on boot 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: swap not being mounted on boot
The problem is running "mkswap", this will generate a new UUID and thus obsolete the information in both the /etc/fstab and /etc/initramfs- tools/conf.d/resume files -- which is why you need to edit those afterwards. -- swap not being mounted on boot https://launchpad.net/bugs/66637 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

thank you tonfa...edited fstab and conf.d resume with value from mkswap - regenerated initrd - and now it all works... for anybody else reading this with the same issue regenerate your initrd with "update-initramfs -u" after you have edited "/etc/initramfs-tools/conf.d/resume" as tonfa described... -- swap not being mounted on boot 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: swap not being mounted on boot
@jens: I think the by-uuid symlink is only updated after a reboot, you can try vol_id I had to do the following to solve it: - correct fstab with the UUID outputted by mkswap (vol_id might work, but /dev/disk/by-uuid definitely don't) - put "RESUME=UUID=" in /etc/initramfs-tools/conf.d resume. The second step should definitely be done in postinst or upgrade for initramfs-tools since without this the swapspace get corrupted after a suspend2disk (currently the resume file is created only on install). Now swsusp works and the laptop don't have any problem of swap disappearing. I think the reason conf.d/resume wasn't created in the first place is because it was a "custom" dapper install (the swap already existed from a previous linux installation, so somehow when initramfs-tools was installed there wasn't any swap space available. -- swap not being mounted on boot 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: swap not being mounted on boot
could the problem be that there are two UUIDs for swap...one refers to the partition and the other refers to the swap-filesystem... when i do mkswap it returns a new UUID for swap and no label...but when i do 'ls -la /dev/disks/by-uuid afterwards the UUID which refers to /dev/hda4 has not changed... since i changed my /etc/fstab to contain the UUID which refers to /dev/hda4 i could do a 'swapon -a' after having done mkswap...if the UUID in fstab had referred to the UUID of the swap-filesystem it would have failed... -- swap not being mounted on boot https://launchpad.net/bugs/66637 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I don't think this is related to bug 48514, though fixing that bug could cause other problems like this by creating a new uuid if we aren't careful. ** Changed in: sysvinit (Ubuntu) Sourcepackagename: sysvinit => None Assignee: (unassigned) => Scott James Remnant -- swap not being mounted on boot https://launchpad.net/bugs/66637 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
