How to add glusterfs node in existing cluster with ansible

I have deploy OKD cluster with glusterfs and now i want to add one more glusterfs node but unable to find any playbook for it.

https://github.com/openshift/openshift-ansible/tree/master/playbooks/openshift-glusterfs

I found one playbook without description

https://github.com/openshift/openshift-ansible/blob/master/playbooks/openshift-glusterfs/upgrade.yml
Solution

  • To add glusterfs node in existing group follow below

    Change inventory like below add node with label in glusterfs

    [glusterfs]
10.1.1.1  glusterfs_devices='[ "/dev/vdb" ]' 
10.1.1.2  glusterfs_devices='[ "/dev/vdb" ]'  openshift_node_labels="type=upgrade"

    Now run playbook with following

    ansible-playbook -i inventory2.ini openshift-ansible/playbooks/openshift-glusterfs/config.yml -e openshift_upgrade_nodes_label="type=upgrade"

    As gluster already installed on 10.1.1.1, above script will add 10.1.1.2 in existing gluster cluster
