Observed behavior

  1. Self-heal is running when there are no volumes/ volume is in stopped state
[root@dhcp35-30 ~]# glustercli volume list
No volumes found


[root@dhcp35-30 ~]# ps aux | grep gluster

  1. Self-heal is not running on one peer even after explicity triggering heal(created & started the new volume)

Expected/desired behavior

Details on how to reproduce (minimal and precise)

Information about the environment:

  • Glusterd2 version used (e.g. v4.1.0 or master):
    glusterd version: v6.0-dev.108.git79d9987
    git SHA: 79d9987
    go version: go1.11.2
    go OS/arch: linux/amd64

  • Operating system used:

  • Glusterd2 compiled from sources, as a package (rpm/deb), or container:

  • Using External ETCD: (yes/no, if yes ETCD version):

  • If container, which container image:

  • Using kubernetes, openshift, or direct install:

  • If kubernetes/openshift, is gluster running inside kubernetes/openshift or outside:

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)

glusterd2.log
glusterd2.log
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

atinmu commented Jan 17, 2019

The revised scope of GCS/1.0 is to make client self heal to heal the files when a file is accessed. glustershd piece needs some work on the shd multiplexing to make the overall work completed which isn't under the scope of GCS/1.0 and hence taking the tag out.
