Describe the issue: There are some new variables introduced that we need to mention in the inventory file for the successful upgrade of the OCS cluster using the upgrade playbook. we now need to document them in the documentation of upgrade playbook 1. openshift_storage_glusterfs_health_timeout=10 Explanation: This variable limits the number of cluster health check retries. The variable value should be multiple of 10, 10 means one retry, 20 means 2 retries and this value should not be less than 10. By default value of this var is 30, so do not specify anything playbook will do 3 retries. bug related to this: https://bugzilla.redhat.com/show_bug.cgi?id=1726608 2. openshift_storage_gluster_update_techpreview=true Explanation: The playbook is in tech preview. set this variable to true for using upgrade playbook. bug related to this: https://bugzilla.redhat.com/show_bug.cgi?id=1748449 3. openshift_storage_glusterfs_fuse_version=<version> Explanation: To upgrade nodes to specific client packages we need to mention the version of which you want to upgrade. for eg. openshift_storage_glusterfs_fuse_version=-3.12.2-18.el7 bug related to this:https://bugzilla.redhat.com/show_bug.cgi?id=1694937
There is one more variable 4. openshift_storage_glusterfs_check_brick_size_health=false Explanation: When the playbook is executing it checks for the brick capacity and while checking brick capacity we need to exclude some bricks from checking, these bricks are the bricks that are part of block hosting volume. For that purpose, we need to set the above variable to false in the inventory file. bug related to this: https://bugzilla.redhat.com/show_bug.cgi?id=1726620
Have added the variables as chapter 7 https://access.redhat.com/documentation/en-us/red_hat_openshift_container_storage/3.11/html-single/deployment_guide/index?lb_target=preview#parameters_of_upgrade_playbook
