In-service software upgrade for RHV-RHGS component is very much required. The bug is already devel_acked, which denotes the doc work is already in progress. Doc verification could be done for this release the bug is targeted for. Providing the qa_ack As Sahina has mentioned most of the items can be borrowed from RHHI guide. But let me draw a outline here: In-Service Software upgrade for RHV-RHGS environment ----------------------------------------------------- 1. Start upgrading the RHGS Nodes one after other following In-Service Software upgrade procedure of RHGS. a. Put one of the RHGS node serving the replica set, in to maintenance from RHV Manager UI b. Perform upgrade on that RHGS node c. Reboot the node d. Activate the node from RHV Manager UI e. Repeat it for other hosts in that replica set 2. Update the gluster clients on Virtualization hosts Virtualization hosts that could be used can be with Red Hat Virtualization(RHVH) host or RHEL hosts In the case of Red Hat Virtualization host, a. Perform upgrade from RHV Manager UI, click on 'upgrade' from RHV Manager UI, which will eventually move the host in to maintenance, then update to the latest redhat-virtualization-host-image update, which contains all the required glusterfs clients packages, reboots the node, and activates the node back in RHV Manager UI In case of RHEL hosts, update the glusterfs client, a. Move the hosts in to maintenance b. Make sure this RHEL host has access to required channels to update to latest glusterfs clients c. Perform update # yum update d. Activate the host from RHV Manager UI @Sahina, Could you verify the technical correctness of the above outline ?

(one minor edit) Verified the doc content for updating RHV-RHGS environment. The content looks good |
