Using LSF with Non-Shared File Systems
LSF installation
To install LSF on a cluster without shared file systems, follow the complete installation
procedure on every host to install all the binaries, man pages, and configuration files.
Configuration files
After you have installed LSF on every host, you must update the configuration files on
all hosts so that they contain the complete cluster configuration. Configuration files
must be the same on all hosts.
Master host
You must choose one host to act as the LSF master host. LSF configuration files and
working directories must be installed on this host, and the master host must be listed
first in
lsf.cluster.cluster_name.
You can use the parameter LSF_MASTER_LIST in
lsf.conf to define which hosts
can be considered to be elected master hosts. In some cases, this may improve
performance.
Fault tolerance
Some fault tolerance can be introduced by choosing more than one host as a possible
master host, and using NFS to mount the LSF working directory on only these hosts.
All the possible master hosts must be listed first in
lsf.cluster.cluster_name. As
long as one of these hosts is available, LSF continues to operate.
