It was intentional since shrinking the cluster fs and LV isn't very common (not supported for gfs2). > For pvmove command, I cannot do online pvmove from one node, > The workaround is to switch VG activation_mode to exclusive, run pvmove > command on the node where VG is activated. > Does this behaviour is by-design? do we do some enhancements in the furture? > or any workaround to run pvmove under shared activation_mode? e.g. --lockopt > option can help this situation? pvmove is implemented with mirroring, so that mirroring would need to be replaced with something that works with concurrent access, e.g. cluster md raid1. I suspect there are better approaches than pvmove to solve the broader problem.
