Managing Queues
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 89.
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
