It sounds like you want a clone rather than two resources.

[ClusterLabs] dont (re)start a ressource if there is already running

2017-11-01 Thread Stefan Krueger 
Hello,

I've a configuration where 2nfs servers are running on different nodes and if 
one node goes down move a ressources to the other one, but dont try to restart 
the ressource, because it is already running.

My config looks like this:
node 1084815873: zfs-serv1
node 1084815874: zfs-serv2
primitive HA_IP-Serv1 IPaddr2 \
params ip=172.16.101.70 cidr_netmask=16 \
op monitor interval=20 timeout=30 on-fail=restart nic=bond0 \
meta target-role=Started
primitive HA_IP-Serv2 IPaddr2 \
params ip=172.16.101.74 cidr_netmask=16 \
op monitor interval=10s nic=bond0
primitive nc_storage ZFS \
params pool=nc_storage importargs="-d /dev/disk/by-partlabel/"
primitive nfs-serv1 systemd:nfs-server \
op monitor interval=5s
primitive nfs-serv2 systemd:nfs-server \
op monitor interval=5s
primitive vm_storage ZFS \
params pool=vm_storage importargs="-d /dev/disk/by-partlabel/"
colocation compl_zfs-serv1 +inf: HA_IP-Serv1 nc_storage nfs-serv1
colocation compl_zfs-serv2 +inf: HA_IP-Serv2 vm_storage nfs-serv2
order start_serv1 nfs-serv1:start nc_storage:start HA_IP-Serv1:start 
symmetrical=false
order start_serv2 nfs-serv2:start vm_storage:start HA_IP-Serv2:start 
symmetrical=false
order stop_serv1 HA_IP-Serv1:stop nfs-serv1:stop nc_storage:stop 
symmetrical=false
order stop_serv2 HA_IP-Serv2:stop nfs-serv2:stop vm_storage:stop 
symmetrical=false
property cib-bootstrap-options: \
have-watchdog=false \
dc-version=1.1.16-94ff4df \
cluster-infrastructure=corosync \
cluster-name=debian \
no-quorum-policy=ignore \
default-resource-stickiness=100 \
stonith-enabled=false \
last-lrm-refresh=1509546667

So is it possible to check if the ressource nfs is already running on the other 
node?

best regards
stefan
