Following is a checklist of the steps you must perform when installing and configuring a CXFS system.
 | Caution: CXFS is a complex product. To ensure that it is installed
and configured in an optimal manner, you must purchase
initial setup services from SGI.
This checklist is not intended to be used directly by the customer, but is provided for reference. It is intended to be used only as an aid; you must be certain to read this entire manual, especially “Configuration Best Practices” in Chapter 2 and Chapter 15, “Troubleshooting”, before attempting to complete these procedures. |
Understand the application use, storage configuration, and I/O patterns at the site. (Not all applications benefit from CXFS; see “Comparison of XFS® and CXFS” in Chapter 1.)
Is there a private network? This is a requirement.
Is system reset configured for all potential metadata servers, as recommended by SGI? Is system reset or I/O fencing configured for all client-only nodes? This is required to ensure data integrity for all nodes. See “Protect Data Integrity on All Nodes” in Chapter 2.
Are there an odd number of server-capable administration nodes with CXFS services running? Is there a client-only tiebreaker node? See “Use an Odd Number of Server-Capable Administration Nodes” in Chapter 2 and “Use a Client-Only Tiebreaker” in Chapter 2.
Read this book, the release notes, and the CXFS 7 Client-Only Guide for SGI InfiniteStorage.
Verify that the network is usable.
Install the CXFS software. See the SGI InfiniteStorage Software Platform release notes, Chapter 7, “Server-Capable Administration Node Installation”, and the CXFS 7 Client-Only Guide for SGI InfiniteStorage.
Completely configure and run a small cluster (such as 3 nodes). See Chapter 9, “Initial Setup of the Cluster”.
Look for errors in the daemon log files in the /var/log/cxfs directory.
If all is well, add the rest of the nodes. If there are problems, see Chapter 15, “Troubleshooting”.
Set up the filesystems. See Chapter 9, “Initial Setup of the Cluster”.
