Adding and Removing Hosts Dynamically
Local resources
for slave hosts
Use LSF_LOCAL_RESOURCES in a localized lsf.conf to define instances of
local resources residing on the slave host:
◆ For numeric resources, defined name-value pairs:
[resourcemap value*resource_name]
◆
For Boolean resources, the value will be the resource name in the form:
[resource resource_name]
When the slave host calls the master host to add itself, it also reports its local
resources. The local resources to be added must be defined in lsf.shared.
If the same resource is already defined in lsf.cluster.cluster_name as
default or all, it cannot be added as a local resource. The shared resource
overrides the local one.
Resources must already be mapped to hosts in the ResourceMap section of
lsf.cluster.cluster_name. If the ResourceMap section does not exist, local
resources are not added.
LSF_LOCAL_RESOURCES is usually set in the slave.config file during installation.
If LSF_LOCAL_RESOURCES are already defined in a local lsf.conf on the slave host,
lsfinstall does not add resources you define in LSF_LOCAL_RESOURCES in
slave.config. You should not have duplicate LSF_LOCAL_RESOURCES entries in
lsf.conf. If local resources are defined more than once, only the last definition is valid.
lsadmin command
Master failover
mbatchd
The lsadmin command is now able to run on a non-LSF host. Use
lsadmin limstartup to start LIM on a newly added dynamic host.
If the master LIM dies, the next master candidate will have the same knowledge
as the master LIM about dynamically added hosts in the cluster.
mbatchd gets host information from master LIM; when it detects that a host has
been added or removed dynamically, mbatchd automatically reconfigures
itself.
After adding a batch host dynamically, you may have to wait a few moments for
mbatchd to detect the host and reconfigure. Depending on system load, mbatchd
may wait up to a maximum of 10 minutes before reconfiguring.
Host configuration in lsb.hosts and lsb.queues
For host configuration in lsb.hosts and lsb.queues to apply to dynamically
added hosts, use default or all, as appropriate, to enable configuration to
apply to all hosts in the cluster.
