Allowing LSF administrators to start LSF daemons (lsf.sudoers)
To allow LSF administrators to start and stop LSF daemons, you should configure the
/etc/lsf.sudoers file. If lsf.sudoers does not exist, only root can start and
stop LSF daemons.
1 Log on as root to each LSF server host.
Start with the LSF master host, and repeat these steps on all LSF hosts.
2 Create /etc/lsf.sudoers on each LSF host and specify the
LSF_STARTUP_USERS and LSF_STARTUP_PATH parameters. For example:
LSF_STARTUP_USERS="lsfadmin user1"
LSF_STARTUP_PATH=/usr/share/lsf/lsf_62/6.2/sparc-sol2/etc
LSF_STARTUP_PATH is normally LSF_SERVERDIR, where the LSF server
binaries (
lim, res, sbatchd, mbatchd, mbschd, etc.) are installed, as defined in
your
LSF_CONFDIR/lsf.conf file.
lsf.sudoers must have file permission mode -rw------- (600) and be
readable and writable only by
root:
# ls -la /etc/lsf.sudoers
-rw------- 1 root lsf 95 Nov 22 13:57
lsf.sudoers
3 Run lsfrestart to restart the cluster:
# lsfrestart
Setting up automatic LSF startup
Use the boot=y option of hostsetup to configure LSF daemons to start
automatically on every LSF server host in the cluster.
