Allowing users to create advance reservations
Advance
reservation user
policies
By default, only LSF administrators or root can add or delete advance
reservations. To allow other users to use brsvadd to create advance
reservations and brsvdel to delete advance reservations, use the
ResourceReservation section of lsb.resources to configure advance
reservation policies for users.
ResourceReservation section (lsb.resources)
A ResourceReservation section specifies:
◆ Users or user groups that can create reservations
◆ Hosts that can be used for the reservation
◆ Time window when reservations can be created
Each advance reservation policy is defined in a separate ResourceReservation
section, so it is normal to have multiple ResourceReservation sections in
lsb.resources.
Examples ◆ Only user1 and user2 can make advance reservations on hostA and
hostB. The reservation time window is between 8:00 a.m. and 6:00 p.m.
every day:
Begin ResourceReservation
NAME = dayPolicy
USERS = user1 user2 # optional
HOSTS = hostA hostB # optional
TIME_WINDOW = 8:00-18:00 # weekly recurring reservation
End ResourceReservation
user1 can add the following reservation for user user2 to use on hostA
every Friday between 9:00 a.m. and 11:00 a.m.:
% user1@hostB> brsvadd -m "hostA" -n 1 -u "user2" -t "5:9:0-5:11:0"
Reservation "user2#2" is created
