Installing Cluster Export Services as part of installing IBM Storage Scale on Linux systems

1. Unmount GPFS file systems and stop GPFS on all nodes by using the following command:

   # mmshutdown -a

2. Configure the CES shared root file system by using the following command:

   # mmchconfig cesSharedRoot=/gpfs/fs0

   Note: It is recommended to configure an independent file system as the CES shared root file system.
3. Start GPFS on all nodes in the cluster by using the following command:

   # mmstartup -a

4. Enable CES on the required nodes by using the following command:

   # mmchnode -–ces-enable –N prnode1,prnode2,prnode3

5. Add to the protocol nodes that the IP addresses designated to be used for CES connectivity by using the following command:

   # mmces address add --ces-node prnode1 --ces-ip CESIPAddress

6. Verify the CES configuration by using the following commands:

   # mmlscluster --ces
   # mmces address list

Currently, there are no services that are enabled. You can verify by using the mmces service list -a command. A sample output is as follows:

No CES services are enabled.

7. Download and extract IBM Storage Scale protocol packages, and then accept the licensing agreement. For more information, see Extracting the IBM Storage Scale software on Linux nodes and Accepting the electronic license agreement on Linux nodes.

   For more information on the location of extracted packages, see Location of extracted packages.

8. Remove conflicting Samba packages that might have been installed on each CES node by issuing one of the following commands, depending on the operating system.
   • On Red Hat Enterprise Linux and SLES, issue the following command:

     # mmdsh -N all rpm -e samba-common --nodeps
     # mmdsh -N all rpm -e samba-client

   • On Ubuntu, issue the following command:

     # mmdsh -N all dpkg -P samba-common
     # mmdsh -N all dpkg -P samba-client

9. Install IBM Storage Scale SMB package by issuing one of the following commands, depending on the operating system.
   • On Red Hat Enterprise Linux and SLES, issue the following command:

     # rpm -ivh gpfs.smb*.rpm

   • On Ubuntu, issue the following command:

     # dpkg -i gpfs.smb*.deb

   For a list of packages for the current IBM Storage Scale release, see Manually installing the IBM Storage Scale software packages on Linux nodes.

10. Install IBM Storage Scale NFS packages by issuing one of the following commands, depending on the operating system.
    • On Red Hat Enterprise Linux and SLES, issue the following command:

      # rpm -ivh NFS_Package_Name1 NFS_Package_Name2 ... NFS_Package_NameN

    • On Ubuntu, issue the following command:

      # dpkg -i NFS_Package_Name1 NFS_Package_Name2 ... NFS_Package_NameN

      If you cannot install NFS package because of any error by using the dpkg -i command, issue the following command:

      # apt install ./NFS_Package_Name1 ./NFS_Package_Name2 ... ./NFS_Package_NameN

      This command installs the specified local package files.
      Note: Before installing IBM Storage Scale 5.1.x on Ubuntu operating system, make sure that upstream NFS Ganesha package is not installed or configured in the protocol nodes. If the NFS Ganesha package is installed or configured, then uninstall the package by using the apt purge nfs-ganesha command.

    For a list of packages for the current IBM Storage Scale release, see Manually installing the IBM Storage Scale software packages on Linux nodes.

11. Install IBM Storage Scale S3 packages by issuing the following commands:
    Install the pre-requisite on all CES nodes.

    rpm -ivh bzip2 boost-thread packages

    Install the respective S3 related RPMs.

    rpm -ivh noobaa-core-* gpfs.mms3*.rpm 

    Before you enable the S3 service, complete the following steps:

    1. Move the logrotate file to the /etc/logrotate.d/ directory.

       cp /usr/local/noobaa-core/src/deploy/standalone/logrotate_noobaa.conf /etc/logrotate.d/logrotate_noobaa.conf

    2. Remove the logrotate script from the output channel (/usr\/local\/noobaa-core\/src\/deploy\/standalone\/logrotate_noobaa.sh).

       rm /etc/logrotate.d/noobaa/logrotate_noobaa.conf

       sed -i 's/,\/usr\/local\/noobaa-core\/src\/deploy\/standalone\/logrotate_noobaa.sh//g' /etc/rsyslog.d/noobaa_syslog.conf

    3. Add rate-limit changes for rsyslog.
       Add imjournalRatelimitInterval 0 and $imjournalRatelimitBurst 0.

       sed -i '/^$EscapeControlCharactersOnReceive/a $imjournalRatelimitInterval 0' /etc/rsyslog.d/noobaa_syslog.conf

       sed -i '/^$EscapeControlCharactersOnReceive/a $imjournalRatelimitBurst 0' /etc/rsyslog.d/noobaa_syslog.conf
