Expected/desired behavior

Volume status output should be proper, It has to show the all volume status , all brick status should be appropriate.

Details on how to reproduce (minimal and precise)

  1. Create PVC
  2. Delete/reboot any one of the gd2 pod
  3. Login to other GD2 pod which is not rebooted or deleted
  4. Then check the volume status
  5. Volume status output showing like, some times "no volumes found", some time " Error getting volume status etc..", some times output is proper.

Information about the environment:

  • Glusterd2 version used (e.g. v4.1.0 or master): v6.0-dev
  • Operating system used: CentOS Linux release 7.5.1804 (Core)
  • Glusterd2 compiled from sources, as a package (rpm/deb), or container: container
  • Using External ETCD: (yes/no, if yes ETCD version):
  • If container, which container image: docker.io/gluster/glusterd2-nightly
  • Using kubernetes, openshift, or direct install: kubernetes
  • If kubernetes/openshift, is gluster running inside kubernetes/openshift or outside: inside

Other useful information

  • glusterd2 config files from all nodes (default /etc/glusterd2/glusterd2.toml)
  • glusterd2 log files from all nodes (default /var/log/glusterd2/glusterd2.log)
  • ETCD configuration
  • Contents of uuid.toml from all nodes (default /var/lib/glusterd2/uuid.toml)
  • Output of statedump from any one of the node

Useful commands

  • To get glusterd2 version 
    glusterd2 --version
  • To get ETCD version 
    etcd --version
  • To get output of statedump 
    curl http://glusterd2-IP:glusterd2-Port/statedump
