Bug Description

Binary package hint: lvm2

I'm using the setup described in https://help.ubuntu.com/community/SbuildLVMHowto.
On Fesity using 2.6.20-5-generic (amd64), I noticed a reproducibe lvm vg metadata corruption while running a build using sbuild in schroot mode on an lvm snapshot, and simultanus entering another lvm-snapshot chroot.
I could reproduce this problem 2 times.

A simple 'vgs' reports this:

  /dev/md3: Checksum error

Hints how to restore lvm metadata:
http://tldp.org/HOWTO/html_single/LVM-HOWTO/#recovermetadata and vgcfgrestore(8).

filing against linux kernel, since I think the problem is rather there than the lvm2 userland tools.

after chatting with fabbionne on #ubuntu-devel, it seems this is actually a duplicate of bug #38409

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!
