[Bug 952063] Re: Cannot boot server using mdadm RAID1 after creating LVM snapshot
When it boots it pauses for a long time trying to mount the root volume and then the screen shows udevd[119]: 'watershed sh -c '/sbin/lvm vgscan; sbin/lvm vgchange -ay'' [264] terminated by signal 9 (Killed) device-mapper: table: 252:8: snapshot: Snapshot cow pairing for exception table handover failed The logical volumes all seem to work correctly after you boot into a livecd - i.e. I can assemble the raid arrays, enable the volume groups and then mount the logical volumes - at least the ones that contain actual filesystems - the ones that contain vms I haven't done anything with. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/952063 Title: Cannot boot server using mdadm RAID1 after creating LVM snapshot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lvm2/+bug/952063/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I can install ubuntu-libvirt-host in the USB livecd and then run the virtual machines, so all the LVM volume groups seem to be intact. I don't seem to have any broken volume groups, but does the fact that the boot process is attempting vgchange -ay mean that the boot will fail if any of the LVM volume groups cannot be started, even if the broken one is not needed to start the system? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/952063 Title: Cannot boot server using mdadm RAID1 after creating LVM snapshot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lvm2/+bug/952063/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 952063] Re: Cannot boot server using mdadm RAID1 after creating LVM snapshot
** Description changed: I'm running a test server on Precise to act as a KVM host. The virtual machines are using LVM logical volumes as backing stores. I have created several virtual machines by taking an LVM snapshot of a base image. When I rebooted the server, it no longer boots. After switching grub to use the console I get messages similar to the ones reported here: http://www.redhat.com/archives/linux- lvm/2012-February/msg00032.html - i.e. Snapshot cow pairing for exception table handover failed The server has 2 2TB SATA drives - partitioned into a smallish sdX1 and a large sdX5. sda1/sdb1 make a mdadm RAID 1 array md0, sda2/sdb2 make - md0. Both md devices are clean. md0 contains vgSystem with logical + md1. Both md devices are clean. md0 contains vgSystem with logical volumes for root, boot and swap. md1 contains vgVMs with logical volumes for all the virtual machines. I can boot the server of a USB stick and then assemble the md arrays and enable the volume groups and everything seems intact ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: grub-pc 1.99-17ubuntu1 ProcVersionSignature: Ubuntu 3.2.0-18.28-generic 3.2.9 Uname: Linux 3.2.0-18-generic x86_64 ApportVersion: 1.94.1-0ubuntu2 Architecture: amd64 Date: Sun Mar 11 11:16:44 2012 InstallationMedia: Ubuntu-Server 12.04 LTS Precise Pangolin - Alpha amd64 (20120130) ProcEnviron: - TERM=xterm - PATH=(custom, no user) - LANG=en_US.UTF-8 - SHELL=/bin/bash + TERM=xterm + PATH=(custom, no user) + LANG=en_US.UTF-8 + SHELL=/bin/bash SourcePackage: grub2 UpgradeStatus: No upgrade log present (probably fresh install) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/952063 Title: Cannot boot server using mdadm RAID1 after creating LVM snapshot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/952063/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This appears to be a bug in lvm, not grub. ** Package changed: grub2 (Ubuntu) = lvm2 (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/952063 Title: Cannot boot server using mdadm RAID1 after creating LVM snapshot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lvm2/+bug/952063/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
