crm_master (8)
crm_master — Manage a master/slave resource's preference for being promoted on a
given node
Synopsis
crm_master [-V|-Q] -D [-l lifetime ]
crm_master [-V|-Q] -G [-l lifetime ]
crm_master [-V|-Q] -v string [-l string ]
Description
crm_master
is called from inside the resource agent scripts to determine which re-
source instance should be promoted to master mode. It should never be used from the
command line and is just a helper utility for the resource agents. RAs use
crm_master
to promote a particular instance to master mode or to remove this preference from it.
By assigning a lifetime, determine whether this setting should survive a reboot of the
node (set lifetime to
forever
) or whether it should not survive a reboot (set lifetime
to
reboot
).
A resource agent needs to determine on which resource
crm_master
should operate.
These queries must be handled inside the resource agent script. The actual calls of
crm_master
follow a syntax similar to those of the
crm_attribute
command.
