10.2. Upgrading an in-service integrated environment

Follow the instructions below to upgrade an integrated Red Hat Virtualization and Red Hat Gluster Storage environment that is online and in-service.
  1. Upgrade the Red Hat Gluster Storage nodes

    Perform the following steps for each Red Hat Gluster Storage node, one node at a time. If you have multiple replica sets, upgrade each node in a replica set before moving on to another replica set.
    1. Stop all gluster services on the storage node that you want to upgrade by running the following commands as the root user on that node.
      # systemctl stop glusterd
      # pkill glusterfs
      # pkill glusterfsd
      # pgrep gluster

      Important

      If glusterd crashes, there is no functionality impact to this crash as it occurs during the shutdown. For more information, see Resolving glusterd crash
