Install and configure Gluster cluster 2. Install and configure RHGS WA 3. Import Gluster cluster into RHGS WA 4. check /var/log/messages on RHGS WA Server Actual results: The log contains lots of errors mentioned above. Expected results: There should be no such errors in the logs. Additional info:
Rohan this because of ansible version problem, Martin can you please update ansible version and then recheck it. we actually did some fix to work tendrl with new ansible version. It won't work with an old version. please update ansible version of server and storage nodes and try it again. I faced the same issue with an old version.
For the latest version, this problem has occurred so we did some change. So this is fixed in new release. Please make sure you are using new release and a new version of Ansible. Rohan, please comment here.
