Fixed In Version:	glusterfs-3.7.1-15	Doc Type:	Bug Fix
Doc Text:	Previously, on glusterd start, UUID was generated and stored in the /var/lib/glusterd/glusterd.info file. This information was static and identical for every instance created. As a consequence, peer probe between instances failed. With this fix, UUID will only be generated on first probe or during volume creation.	Story Points:	---

Comment 3 Anush Shetty 2015-07-28 10:03:12 UTC

Workaround:

Stop glusterd: service glusterd stop

Remove glusterd.info file: rm /var/lib/glusterd/glusterd.info

Start glusterd: service glusterd stop

This needs to be run on all the instances before creating a RHGS cluster.

Tested with glusterfs-3.7.1-12.el7rhgs.

/var/lib/glusterd/glusterd.info file is not generated, when glusterd is installed. This file is generated late now.

The issue is fixed now.

Anush, 

Could you please also confirm the same with the latest RHGS 3.1.1 AMI image ( when AMI is available )

Got information from Anush that there won't be any AMI's available for z-stream releases. Marking this bug as VERIFIED with the comment11

Comment 15 SATHEESARAN 2015-09-04 06:22:14 UTC

This bug was not tested with AMI environment as it was earlier communicated that there won't be any fresh RHGS 3.1.1 AMI images available.

Moving this bug back to ON_QA, as it should be tested with AMI environment only.

Anush,
I am assigning this bug to you, as it needs to be verified with AMI environment.
I have done with testing with glusterd issue and that is no longer seen now ( see comment11 )
