Re: [LVM] Debian looking for a deleted LV swap?

Hi there, I have a warning/error popping up during boot which says Debian can't find one or more of my logical volumes - the one in question is swap_1. This is actually correct, because I removed it and created a new swap LV (named swaparea) - with the relevant updates in fstab, so that I could resize my PV and make space to create a dual boot system.

Whilst the new LV swap works fine, each time I boot up my laptop, or resume it from hibernate, I see this warning/error about swap_1 (which no longer exists.)

Resuming also doesn't work properly now (state doesn't get resumed correctly), but not a huge problem right now.

Does anyone know why swap_1 is still being referenced, and where that reference is? And how I can remove this reference to stop the error? When I posted this question on LinuxQuestions, one of the comments came back saying that the kernel may be hardcoded to look for "swap_1" - but I find that a bit hard to believe, IMO.

Your problem sounds similar to one I had when I installed Debian a while ago. I reused the LVM layout from a previous install of Fedora for testing. I checked /etc/fstab and also tried rebuilding the initramfs as Ralf Mardorf suggested, but the error message remained.

I grepped /etc for "fedora_swap" and found it in the file /etc/initramfs-tools/conf.d/resume

I changed this file so that it read
"RESUME=/dev/mapper/debian-swap"
and NOT
"RESUME=/dev/mapper/fedora-swap"

You should obviously change from "swap_1" to "swaparea" in your case.
I cannot remember if I had to rebuild the initramfs after making this change, so but you might want to try to do so if the problem remains.

My install is on a desktop computer that is powered on 24/7, so I have not tried resume.

Good luck!
