Installing GFS
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.
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.
This chapter describes how to install GFS in the VTS environment.
Note Additional information about managing GFS is provided in the Maintaining GFS for VTS
appendix of the Virtual TapeServer Configuration Guide.
