In addition to the Lustre code, a number of tools exist to help maintain a Lustre filesystem. These are:
e2fsprogs is a set of utilities for maintaining ext2, ext3 and ext4 filesystems. Patches are available to enable e2fsprogs to work with Lustre filesystems.
Lustre servers using ldiskfs require a customized version of e2fsprogs to create and check filesystems. Binary, pre-built RPMs are available from the source and pre-built RPMs.
e2fsprogs must be installed with rpm -U
option. This is because you will almost certainly have an existing version of e2fsprogs will be installed.
If you need to rebuild the binary rpms for your system then you will need the source rpm (SRPM) and a Lustre source tree. The source RPM can then be rebuilt. The path to the Lustre source tree must be passed as an argument to rpmbuild:
$ rpmbuild -D "extra_config_flags --with-lustre=/path/to/lustre" --rebuild e2fsprogs-1.41.90.wc2-7.el6.src.rpm |
Lustre-tar is a modified version of tar, patched to work with a lustre filesystem.
NOTE RHEL6 version of tar includes these patches out-of-the-box. Thanks Redhat!
Lustre-tar is available as source and pre-built RPMs for RHEL and SuSE.
Lustre-diagnostics is a tool to that enables system debugging. The tool works by collecting relevant system and Lustre configuration information. The information is saved into a standard format.
Lustre-diagnostics is available as source and pre-built RPMs. The code consists of a series of scripts.
Lustre-iokit is a suite of tools for benchmarking Lustre systems.
Lustre-iokit is available as an RPM from the source and pre-built RPMs.
