** Description changed:
Binary package hint: lvm2
We have a script that automates the creation and removal of a LVM
snapshots on our VMware servers. Three times now we have had machines go
down when the snapshot was removed. I have logs showing the machine
- going down immediately after
This is 100% reproducible for us. It seems that lvremove is not syncing
before removal of the snapshot. (or perhaps it is wrong to --force
removal of snapshot.) Calling 'sync' immediately before removing the
snapshot seems to mitigate the chance of a crash.
Tested with Ubuntu 6.06.1 i386, clean in
For what its worth it seems Red Hat ES 4 is unaffected. The test script
works as expected on RHES4 with lvm2-2.02.06-6.0.RHEL4, kernel
2.6.9-42.EL.

Hi Ian,
I've reproduced the crash with
Linux anvil 2.6.15-27-server #1 SMP Sat Sep 16 02:57:21 UTC 2006 i686 GNU/Linux
and
Linux ws75 2.6.15-26-386 #1 PREEMPT Thu Aug 3 02:52:00 UTC 2006 i686 GNU/Linux
both are bog standard 6.06 Ubuntu kernels (no custom funny business). Other
versions are probabl
I think this is somehow related to

I've been able to reproduce that bug as well. Recovery protocol is
exactly the same.

I can reproduce this too with 2.6.15-26-386 #1 PREEMPT.
Recovery is simple, the device mapped just gets all out of sync. Rejig
the devices and remove the snapshot and reboot. eg:
mv /dev/mapper/vg_sys-lv_vmware /dev/mapper/vg_sys-lv_vmware_snap ;
mv /dev/mapper/vg_sys-lv_vmware-real /dev/mapper/v
Hi Ben,
I've been able to reproduce this on three different machines including
one machine I specially prepared for testing. This bug is reproducible
without vmware being installed.
If you install dapper with one PV, VG vg_sys and one lv lv_vmware (ext3)
then you should be able to run my crash.sh
Clarification, It seems the lv can also be removed without having to
hack around with the device mapper.

True however, ViewCVS has now been renamed ViewVC which nicely reflects
that it is no longer just for CVS. So going forward is there a way to
install the CVS or Subversion components depending on whether svn or cvs
is installed? Or perhaps ask the user?
I think in any case I should file a bug repo
I was not able to reproduce this with 2.6.15-23-server. Perhaps you
could post a script that reproduces the error along with the specific
kernel / lvm versions installed.
It could also be an load related issue like this one

Please find attached a full kernel trace showing "kernel BUG at
drivers/md/kcopyd.c:145!" (Kernel 2.6.15-23-server)
I've built a 153M VMware machine which reproduces this panic everytime.
If anyone would like to take a look at it I will make the VM available
for download.

In troubleshooting my open LVM kernel bug I've been able to reproduce

I've reproduced this panic with a virgin (kernel.org) 2.6.15.7 (I reused
the ubuntu 2.6.15-23-server config with make oldconfig). I could NOT
reproduce the panic with 2.6.19.1. So logically methinks something was
fixed along the way.
Any pointers for what to do next? Anyone want to lend a hand in
