glusterd: clean up old port and allocate new one on every restart
GlusterD as of now was blindly assuming that the brick port which was already allocated would be available to be reused and that assumption is absolutely wrong. Solution : On first attempt, we thought GlusterD should check if the already allocated brick ports are free, if not allocate new port and pass it to the daemon. But with that approach there is a possibility that if PMAP_SIGNOUT is missed out, the stale port will be given back to the clients where connection will keep on failing. Now given the port allocation always start from base_port, if everytime a new port has to be allocated for the daemons, the port range will still be under control. So this fix tries to clean up old port using pmap_registry_remove () if any and then goes for pmap_registry_alloc () Change-Id: If54a055d01ab0cbc06589dc1191d8fc52eb2c84f BUG: 1221623 Signed-off-by: Atin Mukherjee <amukherj@redhat.com> Reviewed-on: http://review.gluster.org/15005 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Avra Sengupta <asengupt@redhat.com>
