Adopted volume_list Parameter to not activate all vgs? After doing changes to lvm.conf you also need to recreate initramfs. Safest and recommended setup is to use clvmd with dlm and update your vg to a clustered one (also adopt the locking type in lvm.conf). Last step is to integrate dlm/clvmd/lvm in your Pacemaker setup and you are ready to go. [BS] Thanks. I am studying the various docs I have found on setting up clvmd and it looks pretty straightforward. One question I have is do I need to configure the o2cb resource? I do not want a shared file system and therefore I am not going to use OCFS2. It seemed to me that o2cb only makes sense if you have OCFS2.
