Restricting host use by queues
You may want a host to be used only to run jobs submitted to specific queues.
For example, if you just added a host for a specific department such as
engineering, you may only want jobs submitted to the queues engineering1
and engineering2 to be able to run on the host.
1 Log on as root or the LSF administrator on any host in the cluster.
2 Edit lsb.queues, and add the host to the Hosts parameter of specific
queues.
Begin Queue
QUEUE_NAME = queue1
...
HOSTS=mynewhost hostA hostB
...
End Queue
3 Save the changes to lsb.queues.
4 Use badmin ckconfig to check the new queue definition. If any errors
are reported, fix the problem and check the configuration again.
5 Run badmin reconfig to reconfigure mbatchd.
6 If you add a host to a queue, the new host will not be recognized by jobs
that were submitted before you reconfigured. If you want the new host to
be recognized, you must use the command badmin mbdrestart. For
more details on badmin mbdrestart, see “Reconfiguring Your Cluster” on
page 65.
Adding queue administrators
Queue administrators are optionally configured after installation. They have
limited privileges; they can perform administrative operations (open, close,
activate, inactivate) on the specified queue, or on jobs running in the specified
queue. Queue administrators cannot modify configuration files, or operate on
LSF daemons or on queues they are not configured to administer.
To switch a job from one queue to another, you must have administrator
privileges for both queues.
In the lsb.queues file, between Begin Queue and End Queue for the
appropriate queue, specify the ADMINISTRATORS parameter, followed by the
list of administrators for that queue. Separate the administrator names with a
space. You can specify user names and group names. For example:
Begin Queue
ADMINISTRATORS = User1 GroupA
End Queue
