Upgrading IBM Storage Scale non-protocol Linux nodes

Use these steps to upgrade non-protocol nodes that are running on Linux® distributions in an IBM Storage Scale cluster.

Do the following steps for each non-protocol node in the cluster.
  1. Stop all user activity in the file systems on the node that you are upgrading.
  2. If the call home service is enabled on the cluster, run the following command to disable it:
    mmcallhome capability disable

Important: Back up your file systems to ensure that your data is protected.

  1. If file systems are mounted on the node, run the following command to unmount them:
    mmumount all

    Do not use the -f option of the mmumount command.

Note: Before you shut down the current cluster manager node, run the mmchmgr command to move the cluster manager role to another node to avoid unexpected I/O interruption.

  1. Shut down IBM Storage Scale on the node by running the following command.
    mmshutdown
    Note: You do not need to close the mmccrmonitor command and other mm processes because they are handled by IBM Storage Scale upgrade post-install scripts.
    Verify that the GPFS daemon has terminated and that the kernel extensions are unloaded by using mmfsenv -u. If the mmfsenv -u command reports that it cannot unload the kernel extensions because they are busy, then the installation can proceed, but the node must be rebooted after the installation. Kernel extensions are busy means that a process has a current directory in some GPFS file system directory or it has an open file descriptor. The Linux utility lsof can identify the process and that process can then be killed. Retry mmfsenv -u after killing the process and if the command succeeds, then a reboot of the node can be avoided.
    Note:
    • The mmfsenv -u command is normally used with assistance from support or for cases where its usage is specifically documented such as in this scenario.
    • The mmfsenv -u command only checks the local node from which it is run, not all the nodes in the cluster.
  2. Extract the IBM Storage Scale software packages as described in the topic Extracting the IBM Storage Scale software on Linux nodes. For information about the location of extracted packages, see Location of extracted packages.
  3. Change to the directory that contains the IBM Storage Scale package files.
    • If Red Hat® Enterprise Linux or SUSE Linux Enterprise Server (SLES) is installed on the node, run the following command:
      cd /usr/lpp/mmfs/<x.x.x.x>/gpfs_rpms
    • If Ubuntu Linux is installed on the node, run the following command:
      cd /usr/lpp/mmfs/<x.x.x.x>/gpfs_debs
    Where <x.x.x.x> is the version level of IBM Storage Scale that you are upgrading to.
  4. Upgrade the node by using one of the following set of commands. The command choice depends on the operating system and the product edition that is installed on the node.
    Note: The following commands are specific to the current release. If you are upgrading to an earlier release, see the documentation for that release.
    Tip: To determine the currently installed edition, run the following command:
    mmlslicense -L
    Note:
    • Starting with IBM Storage Scale 5.1.0 or later, there are no separate packages for call home, since call home is integrated into the gpfs.base package.
    • If you are upgrading to IBM Storage Scale 5.1.0 or later, you do not need to upgrade the gpfs.kafka package.
    • Red Hat Enterprise Linux 7.x, 8.x, and 9.x
      Note: For rpm packages specific to operating systems such as rhel7, rhel8, and rhel9, you need to install them from specific directories such as rhel7/, rhel8/, and rhel9/.
      • If IBM Storage Scale Standard Edition or IBM Storage Scale Data Access Edition is installed on the node, run the following command. The entire command must be on one line.
        
        rpm -Fvh ./gpfs.gskit*.rpm ./gpfs.gpl*.rpm ./gpfs.docs*.rpm ./gpfs.compression*.rpm 
        ./gpfs.base*.rpm ./gpfs.msg.en_US*.rpm 
        ./gpfs.java*.rpm ./rhel/gpfs.librdkafka*.rpm
        
      • If IBM Storage Scale Advanced Edition or IBM Storage Scale Data Management Edition or IBM Storage Scale Developer Edition is installed on the node, run the following command. The entire command must be on one line:
        
        rpm -Fvh ./gpfs.msg.en_US*.rpm ./gpfs.java*.rpm ./gpfs.gskit*.rpm 
        ./gpfs.gpl*.rpm ./gpfs.docs*.rpm ./gpfs.crypto*.rpm ./gpfs.compression*.rpm 
        ./gpfs.base*.rpm ./gpfs.adv*.rpm ./rhel/gpfs.librdkafka*.rpm
    • SUSE Linux Enterprise Server (SLES)
      • If IBM Storage Scale Standard Edition or IBM Storage Scale Data Access Edition is installed on the node, run the following command. The entire command must be on one line:
        
        rpm -Fvh ./gpfs.gskit*.rpm ./gpfs.gpl*.rpm ./gpfs.docs*.rpm ./gpfs.compression*.rpm 
        ./gpfs.base*.rpm ./gpfs.msg.en_US*.rpm 
        ./gpfs.java*.rpm
      • If IBM Storage Scale Advanced Edition or IBM Storage Scale Data Management Edition is installed on the node, run the following command. The entire command must be on one line:
        
        rpm -Fvh ./gpfs.msg.en_US*.rpm ./gpfs.java*.rpm ./gpfs.gskit*.rpm 
        ./gpfs.gpl*.rpm ./gpfs.docs*.rpm ./gpfs.crypto*.rpm ./gpfs.compression*.rpm 
        ./gpfs.base*.rpm ./gpfs.adv*.rpm 
        
    • Ubuntu Linux
      • If IBM Storage Scale Standard Edition or IBM Storage Scale Data Access Edition is installed on the node, run the following command. The entire command must be on one line:
        
        apt-get install --only-upgrade ./gpfs.gskit*.deb ./gpfs.gpl*.deb 
        ./gpfs.docs.deb ./gpfs.compression.deb 
        ./gpfs.base*.deb ./gpfs.msg.en-us*.deb 
        ./gpfs.java*.deb ./ubuntu/gpfs.librdkafka*.deb
      • If IBM Storage Scale Advanced Edition or IBM Storage Scale Data Management Edition is installed on the node, run the following command. The entire command must be on one line:
        
        apt-get install --only-upgrade ./gpfs.gskit*.deb ./gpfs.gpl*.deb 
        ./gpfs.docs*.deb ./gpfs.crypto*.deb ./gpfs.compression*.deb

        ./gpfs.msg.en-us*.deb ./gpfs.java*.deb 
        ./ubuntu/gpfs.librdkafka*.deb
        
  5. Install the following packages, if needed.
    1. For all editions, if you are upgrading from IBM Storage Scale 4.2.3.x or earlier, install the gpfs.compression package:
      • If Red Hat Enterprise Linux or SUSE Linux Enterprise Server Linux is installed on the node, run the following command from the gpfs_rpms directory:
        rpm -ivh gpfs.compression*.rpm
      • If Ubuntu Linux is installed on the node, run the following command from the gpfs_debs directory:
        apt-get install gpfs.compression*.deb
    2. For all editions, for the gpfs.ext package:
      • If you are upgrading to IBM Storage Scale 5.0.1 or earlier, ensure that you upgrade the gpfs.ext package.
      • In versions 5.0.2 and later, you do not need to upgrade the gpfs.ext package. This package is removed and its functions are merged into other packages.
        Attention: On Ubuntu Linux nodes, in version 5.0.2 and later, you might see an older version of the gpfs.ext package. You can safely remove this package by running the following command:
        dpkg -P gpfs.ext
    3. For IBM Storage Scale Advanced Edition and IBM Storage Scale Data Management Edition, if you plan to use the AFM-based Asynchronous Disaster Recovery (AFM DR) feature, the file encryption feature, or the Transparent cloud tiering feature, you must install the following packages:
      • gpfs.adv
      • gpfs.crypto
  6. After a successful upgrade, rebuild the GPFS portability layer (GPL). For more information, see Building the GPFS portability layer on Linux nodes.
  7. Upgrade performance monitoring packages. For more information, see Manually upgrading the performance monitoring tool and Manually upgrading pmswift.
    Note: You might see the error message pmcollector service critical error on GUI nodes. If this problem occurs, restart the pmcollector service by running the following command on all GUI nodes:
    systemctl restart pmcollector
  8. Upgrade management GUI packages. For more information, see Manually upgrading the IBM Storage Scale management GUI.
  9. Start IBM Storage Scale on the node by running the following command:
    mmstartup
  10. Mount any file systems that are not mounted automatically when the IBM Storage Scale daemon starts.
  11. If you disable the call home service in a preceding step, run the following command to enable it:
    mmcallhome capability enable accept

Repeat the preceding steps on all non-protocol nodes in the cluster. After these steps are done for all non-protocol nodes in the cluster, proceed with the following steps.

  1. Upgrade the license package corresponding to the installed IBM Storage Scale product edition on all nodes in the cluster.
    • For Red Hat Enterprise Linux and SLES:
      mmdsh -N NodeList rpm -Fvh /usr/lpp/mmfs/N.N.N.N/gpfs_rpms/gpfs.license-xxx*.rpm
    • For Ubuntu:
      mmdsh -N NodeList apt-get install --only-upgrade /usr/lpp/mmfs/N.N.N.N/gpfs_debs/gpfs.license-xxx*.deb
      • NodeList is the list of all nodes in the cluster.
      • N.N.N.N is the product version. For example, 5.0.2.0.
      • xxx is the indicator of the product edition:
        • da: Data Access Edition
        • dm: Data Management Edition
        • dev: Developer Edition
        • std: Standard Edition
        • adv: Advanced Edition
  2. If the product edition is Advanced, Data Management, or Developer and file audit logging or clustered watch folder is enabled in the cluster, see Upgrade paths and commands for file audit logging and clustered watch folder.
    • If you are upgrading to IBM Storage Scale 5.1.2 or later and you have previously run the mmmsgqueue config --remove-msgqueue command, no further action is required.
    • If you are upgrading to IBM Storage Scale 5.1.2 or later and you have previously not run the mmmsgqueue config --remove-msgqueue command, do one of the following steps.
      • If you have never enabled the message queue, manually remove the gpfs.kafka package.
      • In all other cases, run the mmmsgqueue config --remove-msgqueue command. This command removes the gpfs.kafka package at the end of the cleanup.
When all the nodes in the cluster are successfully upgraded to the new level, the next step is to complete the upgrade. For more information, see Completing the upgrade to a new level of IBM Storage Scale.
