From Obsolete Lustre Wiki
Jump to navigationJump to search
A set of system configuration utilities are provided with Lustre. These utilities include:
- mkfs.lustre - Used to format a disk for a Lustre service.
- tunefs.lustre - Used to modify configuration information on a Lustre target disk.
- lctl - Used to directly control Lustre via an ioctl interface, allowing various configuration, maintenance and debugging features to be accessed.
- mount.lustre - Used to start a Lustre client or target service.
For examples using these utilities, see:
- Configuring the Lustre File System - mkfs.lustre and tunefs.lustre are used to configure a Lustre file system after installation.
- Running Multiple Lustre File Systems - mkfs.lustre is used to create a second file system and to set up a Lustre installation with two file systems.
- Managing OSTs and related subtopics - lctl is used to show the status of an OST, to deactivate and activate an OST, to set weighting for free space, and to create a new pool and add an OST.
For more information about these utilities, see Chapter 31: System Configuration Utilities (man8) in the Lustre Operations Manual. This chapter also describes other system configuration utilities, such as lustre_rmmod, e2scan, l_getgroups, llobdstat, llstat, lst, plot-llstat, routerstat, and ll_recover_lost_found_objs, as well as utilities to manage large clusters, perform application profiling, and test and debug Lustre.
