A shared file system is a distributed, multihost file system that you can mount on multiple Oracle Solaris operating system (OS) hosts. One Oracle Solaris OS host acts as the metadata server and the others act as clients. You can also designate one or more clients as potential metadata servers, enabling you to switch metadata servers.
Within a shared file system, the Sun QFS software can be installed on Linux clients as well as on Oracle Solaris clients. Unlike a shared Sun QFS Oracle Solaris client, the Linux client is restricted to client-only behavior. It cannot be configured as a potential metadata server. The Linux client supports interaction with SAM-QFS software, but has Sun QFS file system functionality only.
The Sun QFS software functionality is largely the same for the Oracle Solaris and Linux clients. For more information about the Sun QFS Linux client software, see Using Sun QFS and Sun Storage Archive Manager on Linux Clients.
