[Linux-cluster] Mix LVM locking type (1 and 2) on the same host

[Pierre-Alain RIVIERE]

Hello,

I'm trying to setup a 3 nodes CLVM cluster : alpha, beta and omega. My
setup is pretty simple right now, with the following cluster.conf.

I think cluster state is OK as : 
--------------------------------------------
# cman_tool nodes
Node  Sts   Inc   Joined               Name
   1   M    100   2008-07-25 17:40:12  alpha
   2   M    100   2008-07-25 17:40:12  beta
 100   M     48   2008-07-25 17:40:12  omega
---------------------------------------------
# group_tool 
type             level name     id       state       
fence            0     default  00010002 none        
[1 2 100]
dlm              1     clvmd    00020002 none        
[1 2 100]
----------------------------------------------

lvm just works as expected on alpha and beta. But on omega, when I try
to use lvm, I've got these errors :

-----------------------------------------------
# lvcreate -L10M -nsrv04 xenvg
  Rounding up size to full physical extent 12.00 MB
  Error locking on node omega: device-mapper: reload ioctl failed:
Invalid argument
  Failed to activate new LV.
-----------------------------------------------

The 3 servers have the same installation (ubuntu 8.0.4.1, cman, clm),
same configuration

BUT 

on omega I use LVM on another VG which is not clustered.

I use this LVM configuration on the 3 nodes :

    locking_library = "liblvm2clusterlock.so"
    locking_type = 2
    library_dir = "/lib/lvm2"


Is there's a know problem using this mix configuration on the same
server?

Thks.
