[Bug 1896350] Re: nbd locks system?
Hi Dan, Thank you for your bug report. I just came across it now, as I just ran into same issue too. Your reproducer works great, and I have started debugging the issue. At this stage it doesn't seem to be a kernel bug, or a qemu-nbd bug. I think the culprit is systemd-udevd or multipathd, as when I disable systemd-udevd, things work fine. I will add more details to the bug report in a few days or so, once I have determined the root cause and come up with a fix.

(The zero size problem mentioned above also occurs occasionally on ubuntu 18.04, and the workaround is to add a sleep in the user script after modprobe nbd, so that's really a separate problem.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1896350 Title: nbd locks system?

On today's groovy snapshot (with the default kernel, 5.8.0-generic), the original problem is still present; didn't seem to show up until 2nd run of the bug script. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1896350 Title: nbd locks system?

Also seems to work fine on ubuntu 18.04 (fresh, fully updated). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1896350 Title: nbd locks system?

FWIW, running same script on ubuntu 16.04 seems to work better. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1896350 Title: nbd locks system?

Here's the apport file from the VM (which is a very recent clean install); for some reason I couldn't upload it with ubuntu-bug. ** Attachment added: "apport.linux-image-5.4.0-47-generic.0beq9kz0.apport" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1896350/+attachment/5412512/+files/apport.linux-image-5.4.0-47-generic.0beq9kz0.apport -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1896350 Title: nbd locks system?
