Configuring and Maintaining GFS for Virtual TapeServer
The Global File System (GFS) is an advanced feature that allows Linux servers to
simultaneously read and write files on a single shared file system on a SAN. VTS is based on
Linux, and GFS enables multiple VTS servers to access a shared set of pools and virtual
tapes. The Event Management Service (EMS) can then automatically mount virtual tapes
from the GFS pools as if they were separately mounted. Here is an example GFS
configuration:
With GFS, all VTS servers connect to each other over Fibre Channel to the same storage
array, and GFS allows each VTS to access all vaults at the same time. If a server becomes
unavailable, other servers can still access the vaults. No single point of failure exists when
GFS is configured.
The following sections describe how to configure, start, and shut down GFS, and how to join a
cluster and add a vault to a cluster.
