NAME
Lustre - a high-performance cluster file system
SYNOPSIS
A high-performance file system designed for clusters.
DESCRIPTION
Lustre® is a high-performance, massively-scalable, POSIX-compliant
network file system designed for the world’s largest high-performance
compute clusters. Lustre is under active development from Sun
Microsystems (http://www.lustre.org).
Lustre filesystems are made up of multiple services typically
distributed across multiple nodes. Lustre clients can contact these
server nodes over multiple high-speed network fabrics via LNET, the
Lustre NETworking system. Clients then present the filesystem at a
mount point to userspace.
A filesystem is comprised of a MDT , MetaData Target, which stores
directory and file meta-information such as file ownership, timestamps,
access permissions, etc, and a series of OSTs , Object Storage Targets,
which hold the file data in one or more objects. There is typically
not a 1:1 mapping of OST objects and what is presented as a file on a
Lustre client.
Lustre and LNET are implemented as a series of kernel modules, for both
servers and clients. LNET networks are defined in the modprobe.conf
file on all nodes. Lustre is started on the clients and servers using
the mount(8) command.
COMMANDS
mkfs.lustre(8)
Format a physical disk for use as a Lustre server’s backend
storage (aka target).
tunefs.lustre(8)
Modify configuration information on a Lustre target disk.
mount.lustre(8)
A helper program for mount(8) that starts Lustre servers and
clients mounts the client filesystem.
lctl(8)
A low-level interface to control various aspects of Lustre
lfs(1) A user-level interface to control Lustre-specific information
for individual files. lustre_config.sh Format multiple Lustre
targets simultaneously from definitions in a CSV file.
