System Directories and Log Files
System Directories and Log Files
LSF uses directories for temporary work files, log files and transaction files and
spooling.
LSF keeps track of all jobs in the system by maintaining a transaction log in the
work subtree. The LSF log files are found in the directory
LSB_SHAREDIR/cluster_name/logdir.
The following files maintain the state of the LSF system:
lsb.events
lsb.events.n
LSF uses the lsb.events file to keep track of the state of all jobs. Each job is
a transaction from job submission to job completion. LSF system keeps track
of everything associated with the job in the lsb.events file.
The events file is automatically trimmed and old job events are stored in
lsb.event.n files. When mbatchd starts, it refers only to the lsb.events file,
not the lsb.events.n files. The bhist command can refer to these files.
Job script files in the info directory
When a user issues a bsub command from a shell prompt, LSF collects all of
the commands issued on the bsub line and spools the data to mbatchd, which
saves the bsub command script in the info directory for use at dispatch time
or if the job is rerun. The info directory is managed by LSF and should not be
modified by anyone.
Log directory permissions and ownership
Ensure that the permissions on the LSF_LOGDIR directory to be writable by
root. The LSF administrator must own LSF_LOGDIR.
Support for UNICOS accounting
In Cray UNICOS environments, LSF writes to the Network Queuing System
(NQS) accounting data file, nqacct, on the execution host. This lets you track
LSF jobs and other jobs together, through NQS.
