• The NFS server as well as the IP address must be on the same node as the file sys-
tem.
crm(live)configure# colocation nfs_with_fs inf: \
nfs_group filesystem_resource
• The NFS server as well as the IP address start after the file system is mounted:
crm(live)configure# order nfs_second mandatory: \
filesystem_resource nfs_group
• The file system must be mounted on a node after the drbd resource is promoted to
master on this node.
crm(live)configure# order drbd_first inf: \
drbd_resource:promote filesystem_resource
5.6 Specifying Resource Failover
Nodes
To determine a resource failover, use the meta attribute migration-threshold. For exam-
ple:
crm(live)configure# location r1-node1 r1 100: node1
Normally r1 prefers to run on node1. If it fails there, migration-threshold is checked
and compared to the failcount. If failcount >= migration-threshold then it is migrated
to the node with the next best preference.
Start failures set the failcount to INFINITY depends on the
start-failure-is-fatal
option. Stop failures cause fencing. If there's no
STONITH defined, then the resource will not migrate at all.
