Prerequisites and co-requisites

  • - Prerequisites

    You may use this 5.0.1.2 package to perform a First Time Install or to upgrade from an existing 4.2.0.0 - 5.0.1.1 (If upgrading node by node ) or 3.5.0 - 5.0.1.1 (If you shutdown and upgrade the entire cluster).

Known issues

  • - Problems discovered in IBM Spectrum Scale releases

    None.

Installation information

  • - Downloading Images

    Choose the download option "Download using Download Director" to download the new Spectrum Scale package and place it in any location desired on the install node.
    Note, if you must (not recommended) use download option "Download using your browser (HTTPS)", instead of clicking on the down arrow to the left of the package name, you must right-click on the package name and select the Save Link As.. option. If you just click on the download arrow, the browser will likely hang.

  • - Installing IBM Spectrum Scale update for Linux on Power Systems

    After you have downloaded the IBM Spectrum Scale 5.0.1.2 update, follow the steps below to install the fix package:

    1. Ensure the package is executable using ls -l command.

      You should see something similar with permissions like:
           -rwx r--r-- l root root 110885866 Apr 27 15:52 /download_dir/package_name.

    3. Follow the installation and migration instructions in your IBM Spectrum Scale Installing and upgrading.
  • - Upgrading GPFS nodes

    In the below instructions, node-by-node upgrade cannot be used to migrate from GPFS 4.1 or prior releases. For example, upgrading from 4.1.1.16 to 5.0.1.2 requires complete cluster shutdown, upgrade install on all nodes and then cluster startup.

    Upgrading GPFS may be accomplished by either upgrading one node in the cluster at a time or by upgrading all nodes in the cluster at once. When upgrading GPFS one node at a time, the below steps are performed on each node in the cluster in a sequential manner. When upgrading the entire cluster at once, GPFS must be shutdown on all nodes in the cluster prior to upgrading.

    When upgrading nodes one at a time, you may need to plan the order of nodes to upgrade. Verify that stopping each particular machine does not cause quorum to be lost or that an NSD server might be the last server for some disks. Upgrade the quorum and manager nodes first. When upgrading the quorum nodes, upgrade the cluster manager last to avoid unnecessary cluster failover and election of new cluster managers.

    1. Prior to upgrading GPFS on a node, all applications that depend on GPFS (e.g. DB2) must be stopped. Any GPFS file systems that are NFS exported must be unexported prior to unmounting GPFS file systems.
    2. Stop GPFS on the node. Verify that the GPFS daemon has terminated and that the kernel extensions have been unloaded (mmfsenv -u). If the command mmfsenv -u reports that it cannot unload the kernel extensions because they are "busy", then the install can proceed, but the node must be rebooted after the install. By "busy" this means that some process has a "current directory" in some GPFS filesystem directory or has an open file descriptor. The freeware program lsof can identify the process and the process can then be killed. Retry mmfsenv -u and if that succeeds then a reboot of the node can be avoided.
    3. Upgrade GPFS as follows(make sure to be in the same directory as the files):

      1. For Linux:

        For SLES or RedHat Enterprise Linux:

        rpm -Fvh gpfs*.rpm
        rpm -ivh gpfs.license.*.rpm (if you are updating from 4.2.1.2 or older version)
        rpm -ivh gpfs.compression.*.rpm (if you are updating from older than 5.0.0.0 version)

        For Debian and Ubuntu Linux:

        dpkg -i gpfs*.deb

        Recompile any GPFS portability layer modules you may have previously compiled. For more information, reference: Building the GPFS portability layer on Linux nodes




      2. For AIX:
        Use the 'inutoc .' command to create a .toc file which will be used by the installp command. The .toc file will be created in the current working directory.
        Once the .toc file is created, Upgrade GPFS using the installp command or via SMIT on the node. If you are in the same directory as the install packages and the .toc file, an example command might be:

        installp -agXYd . gpfs

Additional information

  • - Notices
  • - Package information

    The images listed below and contained in the Self Extracting Package (SE-Package) are maintenance packages for IBM Spectrum Scale. The images are a mix of normal RPM or DEB images that can be directly applied to your system.

    The packages can be used for new install or update from a prior level of IBM Spectrum Scale.

    After all RPMs or DEBs are installed, you have successfully updated your IBM Spectrum Scale product.

    Before installing IBM Spectrum Scale, it is necessary to verify that you have the correct levels of the prerequisite software installed on each node in the cluster. If the correct level of prerequisite software is not installed, see the appropriate installation manual before proceeding with your IBM Spectrum Scale installation.

    For the most up-to-date list of prerequisite software, see the IBM Spectrum Scale FAQ in the IBM® Knowledge Center .

    • Fix an AFM:data mismatch in read if replication factor is more then 1. IJ06220
    • Fix an error in the mmsysmonitor log and "ks_url_warn" event when upgrading to 5.0.1. Issue will disappear after a mmsysmoncontrol restart. While error is 'active' the keystone server (object authentication) is not monitored correctly. IJ06116
    • Fix mmbackup handling of -g option. It should use config var sharedTmpDir to determine the relative or absolute paths. IJ06116
