File Systems

Home Directories

All production OCF and SCF LC systems share home directories that reside on global file system /g, NFS mounted from several dedicated servers.
See EZFILES and Home Directories for details.

Parallel File Systems

Parallel file systems are large, shared, Lustre file systems used for parallel I/O.
See EZFILES, Parallel File Systems, and Lustre Parallel File Systems for details.

Temporary File Systems

Various temporary file systems (global and local) are for system use, temporary storage of I/O local to each machine, or large temporary storage for I/O shared among many machines.
See EZFILES and Temporary File Systems for details.

/usr/workspace File Systems

1 TB of NFS mounted file space is provided for each user and group.
These file systems are similar to home directories, but are not backed up. For details, see EZFILES and /usr/workspace File Systems.

/usr/gapps and /usr/gdata File Systems

LC provides shared, collaborative, NFS mounted file space for user developed and supported applications and data on LC systems.
See /usr/gapps, /usr/gdata File Systems and /usr/gapps File System for details.

Archival Storage Hardware

High Performance Storage System (HPSS) archival storage is available on all LC production systems.
For more information, see EZSTORAGE, Archival HPSS Storage, and the HPSS User Manual.

File System Status

The file system status displays real-time status information on LC file systems. It also shows which file systems are mounted by each cluster and file system bandwidth between clusters.
