Description Josef Bacik 2006-08-29 13:15:28 EDT
Description of problem:
My system has a local LV and clustered LV's.  On bootup when it's trying to do
the initial vgscan to activate any local LV's lvm.static will segfault.  If I go
back to the U3 version it does not segfault.

Version-Release number of selected component (if applicable):

How reproducible:
Every time

Steps to Reproduce:
1. Have a local FS on LVM
2. Have clustered LV's
3. Boot
Actual results:
lvm.static will segfault

Expected results:
it should not segfault

Additional info:
I got a core from the segfault.  I will look into this when I have more time,
but for now the bt is

the core I'm uploading was made on an x86_64 machine.

Package versions please e.g. kernel, device-mapper, lvm2, lvm2-cluster
Comment 3 Alasdair Kergon 2006-08-29 14:00:08 EDT

Comment 5 Josef Bacik 2006-08-29 18:38:00 EDT
Using locking_type=3 makes it so it does not segfault.
Comment 6 Josef Bacik 2006-08-29 18:39:20 EDT
btw it seems you can reproduce this panic easily while the system is running
with everything mounted.

Comment 20 Alasdair Kergon 2006-11-27 16:30:34 EST
There is a simple workaround in comment #5, so I see no point in doing a hotfix.
