LMT Configuration for DAL
Configure Lustre monitoring tool (LMT) for direct-attached Lustre (DAL) on CLE 6.x.
CAUTION: As stated in the "Migration Caveats" section of the introduction, this migration process does not include a tested procedure for preserving a DAL LMT database during migration. If this site wishes to preserve an existing LMT database, do not use this procedure as it will result in loss of existing data.
The Lustre® monitoring tool (LMT) for direct-attached Lustre (DAL) on Cray Linux environment (CLE 6.0) requires some manual configuration during the software installation process.
- Configure Storage for the LMT Database
- At least 40GB of storage space must be made available to the MGS node. See LMT Disk Usage.
- Configure the LMT MySQL Database
- The IMPS configuration does not set up this database, so this must be configured manually for CLE 6.0 UP01 and later releases. See Configure LMT MySQL Database for DAL.
- Configure the LMT GUI (Optional)
- See Configure the LMT GUI.
Use the configurator to configure the LMT for DAL on CLE 6.0. Guidance is provided for each LMT configuration setting in the cfgset utility.
The
cray_lmt configurator template configures LMT settings for specific nodes when they are booted. The default system configuration value for the LMT service is disabled (false). Log in to the SMW as root and use the cfgset command to modify the cray_lmt configuration settings to configure LMT.smw# cfgset update -s cray_lmt -m interactive CONFIG_SET
