Description Rachael 2020-02-28 08:57:04 UTC 
Description of problem:

On a setup with more than 1000 volumes, extra parameters are required to be added to the glusterfs daemonset and heketi deployment config as mentioned in this KCS article: https://access.redhat.com/articles/4383621. 

During upgrade of OCS, due to the recreation of templates, these parameters are lost and has to be added again while creating the new templates. A note should be added to the doc to indicate the same.
