crm_failcount (8)
crm_failcount — manipulate the failcount attribute on a given resource
Synopsis
crm_failcount [-?|-V] -D -u|-U node -r resource
crm_failcount [-?|-V] -G -u|-U node -r resource
crm_failcount [-?|-V] -v string -u|-U node -r resource
Description
Heartbeat implements a sophisticated method to compute and force failover of a resource
to another node in case that resource tends to fail on the current node. A resource carries
a resource_stickiness attribute to determine how much it prefers to run on a
certain node. It also carries a resource_failure_stickiness that determines
the threshold at which the resource should failover to another node.
The failcount attribute is added to the resource and increased on resource monitoring
failure. The value of failcount multiplied by the value of
resource_failure_stickiness determines the failover score of this resource.
If this number exceeds the preference set for this resource, the resource is moved to
another node and not run again on the original node until the failure count is reset.
The crm_failcount command queries the number of failures per resource on a
given node. This tool can also be used to reset the failcount, allowing the resource to
run again on nodes where it had failed too often.
