CPU and Operating System

Processor is 64-bit

To determine the processor type, run

$ uname -m
x86_64

If the output includes "x86_64," the processor is 64-bit. If it includes "i386," "i486," "i586," or "i686," it is a 32-bit processor, which is not supported by data-fabric software.

If the results are "unknown," or none of the above, use one of the following commands.

$ uname -a
Linux mach-name 2.6.35-22-server #33-Ubuntu SMP Sun Sep 19 20:48:58 UTC 2012 x86_64 GNU/Linux

In the cpuinfo file, the flag 'lm' (for "long-mode") indicates a 64-bit processor.

$ grep flags /proc/cpuinfo

Supported Operating Systems

For the supported operating systems, see Operating System Support Matrix.

To determine the name and version of the installed operating system, run the lsb_release -a command.

There is no problem if the lsb_release command reports "No LSB modules are available."

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 10.10
Release:        10.10
Codename:       maverick

If the lsb_release command is not found, try one of the following alternatives:

$ cat /proc/version
Linux version 2.6.35-22-server (build@allspice) (gcc version 4.4.5 (Ubuntu/Linaro 4.4.4-14ubuntu4) ) #33-Ubuntu SMP Sun Sep 19 20:48:58 UTC 2012

$ cat /etc/*-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=10.10
DISTRIB_CODENAME=maverick
DISTRIB_DESCRIPTION="Ubuntu 10.10"

If you determine that the node is running an older version of a supported OS, upgrade to at least a supported version, and test the upgrade before proceeding. If you find a different Linux distribution, such as Fedora or Gentoo, you must reformat and install a supported distribution on the node.
