Run lsadmin ckconfig -v and correct the problems shown in the command
output.
See problem “2 Host does not have a software license” on page 55 and Chapter 4,
“Working with LSF Licenses” for more information.
◆ Ownership of the LSF files and directories.
The LSF primary administrator should own all LSF directories and most files.
In particular, LSB_SHAREDIR (e.g.,
/usr/share/lsf/lsf_62/work ) must be
owned and writable by the LSF primary administrator.
The LSF administration commands
lsadmin and badmin must be owned by
root and have the file permission mode -rwsr-xr-x (user ID bit for the owner
is
setuid).
See problem “5 lsadmin or badmin fails” on page 59 for more information.
5 lsadmin or
badmin fails
The LSF administration commands lsadmin and badmin, or the eauth executable
might give the error messages like:
◆ User permission denied.
◆ Operation not permitted.
Check the following:
◆ If you ran lsfinstall as root, lsfadmin, badmin, and eauth have the file
permission mode
-rwsr-xr-x (4755) so that the user ID bit for the owner is
setuid. However, on the file system where LSF was installed, setuid permission
may be turned off. Do one of the following:
❖ If lsadmin, badmin, and eauth are in a directory shared through NFS, share
and mount the LSF_TOP directory with
setuid enabled. Do not mount with
the
nosuid flag.
❖ If your site does not permit this, you must copy lsadmin and badmin, and
eauth to a local directory on each host in the cluster. (make sure the local
directory is in the PATH; for example,
/usr/bin or /bin.)
◆ If you ran lsfinstall as a non-root user to install a multi-user cluster, you must
manually change the ownership for
lsadmin and badmin to root and the file
permission mode to
-rwsr-xr-x (4755) so that the user ID bit for the owner is
setuid.
Use the following commands to set the correct owner, user ID bit, and file
permission mode for a multi-user cluster:
# chown root lsadmin badmin eauth
# chmod 4755 lsadmin badmin eauth
◆ You may also see these messages if you run the bsub command as root.
By default, you cannot submit jobs with
bsub as root. This is a normal security
precaution. If you need to submit jobs as
root, set LSF_ROOT_REX=local in
LSF_CONFDIR/lsf.conf.
If you continue to see this message, it means that the remote host cannot securely
determine the user ID of the user requesting remote execution.
