ok, I have recompiled it with --with-cluster=internal, but still seeing:

WARNING: Locking disabled. Be careful! This could corrupt your metadata.

in lvm.conf I have locking_type = 3, complete configure line was:

./configure --with-clvmd=cman  --with-cluster=internal 
--libdir=/usr/lib64/ --enable-dmeventd --enable-cmdlib

cluster was compiled with following options:

./configure --disable_kernel_check --enable_xen --libdir=/usr/lib64/ 
--without_gnbd --without_kernel_modules --without_gfs --without_gfs2

running on kernel 2.6.25

any suggestion?

thanks steve
