[Kernel-packages] [Bug 1423796] Re: Unable to mount lvmcache root device at boot time
yah I have actually never seen a bug fixed on the Ubuntu bug tracker, just deal with it upstream or use a different distribution. IMO Ubuntu should delete bugs.launchpad.net and just merge pull requests on github/etc. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1423796 Title: Unable to mount lvmcache root device at boot time Status in initramfs-tools package in Ubuntu: Confirmed Status in linux package in Ubuntu: Confirmed Status in lvm2 package in Ubuntu: Confirmed Bug description: I'm experimenting with Vivid Vervet on a virtual machine and tried a new LVM feature, lvmcache. I made a cache for the root file system, rebuilt the initrd and rebooted the VM. At boot time, the system failed to activate the root LV. After some investigation, I found out, it's because the initrd is missing some essential stuff needed for activating a cached LV. The initrd was missing the dm-cache module. I regenerated the initrd with explicitly listing dm-cache in /etc/initramfs-tools/modules, but the system still can't boot up, because now it is missing the /usr/sbin/cache_check utility. As SSDs are becoming more and more common, I think it will be common to use them as cache for root file systems, thus it is mandatory to make sure that an initrd can mount an lvmcached root device when necessary, preferably without /etc/initramfs-tools/modules and other manual initrd hacking.

I have managed to narrow it down somewhat but still looking for a fix. After disabling splash and quiet from grub I noticed it's waiting at /scripts/init-bottom/udev in initrd and continues after 61 seconds. Not surprisingly i found a "udevadm control --timeout 61 --exit" line in there. Well, why does it fail so badly it waits for timeout before exiting? After quite a bit of googling I found this: http://us.generation-nt.com/answer/problem-lvm-gets-stuck-during-booting-due-recent-uevent-change-help-205241751.html Ari Savolainen writes: An init script (/scripts/init-bottom/udev in initrd) issues command "udevadm control --timeouta --exit". At the same time udevd is executing "/sbin/lvm vgchange -a y" (from /lib/udev/rules.d/85-lvm2.rules) that calls ioctl to resume a logical volume. After that lvm gets stuck forever. Booting continues after the 61 second timeout. Milan Broz writes: If you call vgchange or even vgscan from udev rule, it is completely wrong. This is not lvm upstream udev rule btw. This makes me slightly worried, does this cause any other problems than a annoyingly slow boot? Is there any way to fix this? I this a known issue?
