[Bug 245660] New: Suspend to disk with LVM partitions
https://bugzilla.novell.com/show_bug.cgi?id=245660 Summary: Suspend to disk with LVM partitions Product: openSUSE 10.2 Version: Final Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Mobile Devices AssignedTo: behlert@novell.com ReportedBy: felix.rommel@web.de QAContact: qa@suse.de Please fix the problem not being able to suspend to RAM/Disk if the root partition is in a logical volume. See: https://bugzilla.novell.com/show_bug.cgi?id=228572#c12 Currently openSUSE 10.2 is not good for using it on a laptop - if you use LVM - because you cannot suspend to disk... Because 10.3 is foremost planned for September, it would be great if you fix this problem in 10.2. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

If stefan says it has to wait, I'm afraid it has to wait. Felix, if initrd does not scare you, try to move lvm init before resume handling; that should get resume from LVM to work. If you can do that with nice and obvious patch, then _maybe_ we can think about fixing it for 10.2. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

Also, messing around with the initrd creation has the potential to screw up other users, so this must be tested extensively. Unless we find out it is doable with a trivial, non-intrusive patch, it will have to wait for 10.3. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

Suspend with LVM does not work at all, because the machine hangs after printf("suspend: Snapshotting system\n"); attempts = 2; do { if (set_image_size(snapshot_fd, image_size)) { error = errno; break; } if (!atomic_snapshot(snapshot_fd, &in_suspend)) { here. I think if we stop all threads, the LVM thread ksnapd gets frozen (it gets created in linux/drivers/md/dm-snap.c with ksnapd = create_singlethread_workqueue("ksnapd"); ) and this then deadlocks the rest of the suspend process, but i am not sure. So as it is now, suspend on LVM does not work _at all_, so i can not do anything in userland to fix it. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
https://bugzilla.novell.com/show_bug.cgi?id=245660 ------- Comment #6 from seife@novell.com 2007-02-15 11:57 MST ------- it fails the same way when trying the in-kernel suspend (almost the same; s2disk seems to let the CPU idle, the cursor is still blinking. In-kernel sends the CPU to 100% and the cursor stops blinking). Last thing seen is always "suspending consoles", this is with 2.6.20 on STABLE. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

Suspend to Disk works with 10.3 Alpha1 + updates 2007-03-25 on my Thinkpad Z61m with LVM, now.
Interesting. Can you tell us your kernel version (uname -r)? Did you need to unload dm_snapshot to make it work?

Suspend to RAM is a totally different thing than suspend to disk. _PLEASE_ file a different bug.
I didn NOT unload any drivers - I suspend with Gnomes old logout dialog, cause current version of gnome-main-menu is broken.

Linux thinksusez29 2.6.21-rc4-git5-3-default #1 SMP Wed Mar 21 19:44:10 UTC 2007 i686 i686 i386 GNU/Linux

Created an attachment (id=126919) --> (https://bugzilla.novell.com/attachment.cgi?id=126919&action=view) [edit] output of messages while suspend to disk
So now it is suspend to disk again? I'm afraid mixing this all up in this bug, which is mainly about the initrd and the suspend tools not working well wrt. suspend on LVM and about dm_snapshot possibly having problems wrt. suspend, is not a good idea. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

To make it clear: Comment #15 must be: Suspend to DISK (I accidently wrote "...to RAM") with root partition in LVM does work sometimes with 10.3 Alpha1 + updates 2007-03-25 . Sometimes means, that sometimes after clicking Hibernate in Gnome dialog, computer starts suspend to DISK but freezes and does not shutdown clearly. But at other times computer suspends and shutdown is OK. I will create a NEW bug report for Thinkpad Z61m not suspending to RAM - with information given at http://en.opensuse.org/S2ram. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
