Lustre 1.6 Operations Manual

3.2.2 Lustre Tools
The lustre-.rpm package, required for proper Lustre setup and
monitoring, contains many tools. The most important tools are:
■ lctl - Low-level configuration utility that can also be used for troubleshooting
and debugging.
■ lfs - Tool to read/set striping information for the cluster, as well as perform
other actions specific to Lustre filesystems.
■ mkfs.lustre - Tool to format Lustre target disks.
■
mount.lustre - Lustre-specific helper for mount(8).
Another tool is LNET self-test, which helps site administrators confirm that LNET
has been properly installed and configured. The self-test also confirms that LNET
and the network software and hardware underlying it are performing according to
expectations.
3.2.3 Other Required Software
Although we provide some tools and utilities, Lustre also requires several separate
software tools to be installed.
3.2.3.1 Core-Required Tools
■
e2fsprogs: Lustre requires very modern versions of e2fsprogs that understand
extents—use e2fsprogs-1.38-cfs1 or later, available at:
http://downloads.clusterfs.com/public/tools/e2fsprogs/latest
Note – This directory contains both SUSE Linux Enterprise Server (SLES) and Red
Hat Enterprise Linux (RHEL) versions of e2fsprogs.
Note – You may need to install e2fsprogs with rpm -ivh --force to override any
dependency issues of your distribution. Lustre-patched e2fsprogs only needs to be
installed on machines that mount backend (ldiskfs) filesystems, such as OSS, MDS
and MGS nodes.
■
■
Perl: Various userspace utilities are written in Perl. Any modern Perl should work
with Lustre.
Build tools: If you are not installing Lustre from RPMs, normally you can use a
GCC compiler to build Lustre. Use GCC 3.0 or later.
