Installing cloud services on IBM Spectrum Scale nodes

This topic describes the procedure for installing cloud services on IBM Spectrum Scale™ nodes.

Before you begin, ensure that you have created a node class. For more information, see Creating a user-defined node class for Transparent cloud tiering or Cloud data sharing. Also, ensure that your server meets the required prerequisites. For more information, see Software requirements for cloud services.

Note: Cloud service creates the following folders after installation:

• /var/MCStore
• <filesystem>/.mcstore
• /opt/ibm/MCStore

Do not make any changes to these folders in order to avoid any undesired results.

The cloud services installation is not included in the IBM Spectrum Scale installation toolkit workflow. It needs to be installed separately on top of the IBM Spectrum Scale cluster. However, the cloud service RPMs are available with the IBM Spectrum Scale package.

Note: The cloud services RPMs are available only with the IBM Spectrum Scale Advanced Edition. You can verify this by issuing this command: rpm -qa | grep gpfs.adv

With each build of IBM Spectrum Scale, two RPMs are available for cloud services:

• gpfs.tct.server-x.x.x.x86_64.rpm. This is the server package that is installed on the cloud service nodes. These nodes must have outbound WAN connectivity to be able to support data migration between IBM Spectrum Scale cluster and the cloud object storage.
• gpfs.tct.client-x.x.x.x86_64.rpm. This is the client package that contains the cloud service binary files (specifically the data manager commands). This package must be installed on all remaining cluster nodes to activate ILM-based file migration or file recall that is initiated from that node (every node in the cluster is safe). The client RPM is not required on the nodes where the server package is installed.

1. Copy the server RPMs to the desired nodes.
2. Install cloud services package on each node by issuing this command: rpm -ivh gpfs.tct.server-x.x.x.x86_64.rpm
   Note: By default, the cloud service is installed under the /opt/ibm/MCStore directory.
3. Install the client package on the desired nodes by issuing this command: rpm -ivh gpfs.tct.client-x.x.x.x86_64.rpm
4. To install cloud services client package on the SLES distributions, issue this command: zypper install gpfs.tct.client-x.x.x.x86_64.rpm
