glusterd : glusterd fails to start when peer's network interface is down
Problem: glusterd fails to start on nodes where glusterd tries to come up even before network is up. Fix: On startup glusterd tries to resolve brick path which is based on hostname/ip, but in the above scenario when network interface is not up, glusterd is not able to resolve the brick path using ip_address or hostname With this fix glusterd will use UUID to resolve brick path. >Reviewed-on: https://review.gluster.org/17813 >Smoke: Gluster Build System <jenkins@build.gluster.org> >Reviewed-by: Prashanth Pai <ppai@redhat.com> >CentOS-regression: Gluster Build System <jenkins@build.gluster.org> >Reviewed-by: Atin Mukherjee <amukherj@redhat.com> Change-Id: Icfa7b2652417135530479d0aa4e2a82b0476f710 BUG: 1482857 Signed-off-by: Gaurav Yadav <gyadav@redhat.com> Reviewed-on: https://review.gluster.org/18063 Reviewed-by: Prashanth Pai <ppai@redhat.com> Smoke: Gluster Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Atin Mukherjee <amukherj@redhat.com>
