How to sync the /usr mount point. When I try to create /dev/drbd0 sync between to servers it will not start the sync process the usr mount point is part of a LVM partition. I can sync only mount points that are not part of LVM. eg /dev/sdc1 ext4 partition. The problem I think is that /usr cannot be unmounted to start the process. So how do you sync /usr /var / partitions ???????? I am using LCMC 1.1.0 (Linux Cluster Management Console) Java app to configure.
