Hello Vladislav,

thanks for Your reply! I would not have any problem with switching
to corosync-driven CLVMD, but for some reason, only supported stack
in RHEL CLVMD is cman.. does somebody know why is that? Is it safe
to recompile clvmd with corosync support (+ apply mentioned patch)
and use that? I've been using corosync till now anyways, so I'd like
to stick to it if possible...
