Updating Hardware Nodes in a Parallels Cloud Storage Cluster

To update a Parallels Cloud Storage cluster of Parallels Cloud Server Hardware Nodes, update each Node as described below.

  1. Clean the Node from potentially obsolete update data:

    # yum clean all

  2. Update Parallels Cloud Server packages:

    # yum update

    # vzreboot

After the update, you can check that

  • the Node has been updated successfully:

    # prlsrvctl info | grep Server

    Version: Server 6.0.17195.922164

    OS: Parallels Cloud Server 6.0.0 (1622) (2.6.32-042stab081.3)

  • High Availability has remained enabled for the Node after the update:

    # shaman stat

  • the Node has remained in the cluster. E.g., for cluster pcs1 :

    # pstorage -c pcs1 top

Repeat the procedure above for each Hardware Node in the Parallels Cloud Storage cluster.
