Description Atin Mukherjee 2018-11-19 02:21:30 UTC

Description of problem:

Background of the problem is captured at https://bugzilla.redhat.com/show_bug.cgi?id=1650138#c6 .

As part of an OCS upgrade process, glusterd isn't brought up with an interim mode ( glusterd --xlator-option *.upgrade=on -N) when the underlying RHGS NVR has changed. This command is run in the post install script of the glusterfs spec when an rpm is upgraded. This command is needed to ensure all the gluster bricks are started with the regenerated volfiles based on the latest bits.

Missing out this step as part of an OCS upgrade process can cause severe problems/side effects as explained in https://bugzilla.redhat.com/show_bug.cgi?id=1650138#c6

Version-Release number of selected component (if applicable):
All OCS versions
