<div style="direction: ltr;font-family: Arial;color: #000000;font-size: 10pt;">Hi,<br>
<br>
I have an active/passive cluster configuration and I am trying to make a virtual IP resource sticky such that it does not move back to a node after a fail-over. In my setup, I have a location preference for the virtual IP to the "primary" node:<br>
pcs resource show --full<br>
Resource: mda-ip (class=ocf provider=heartbeat type=IPaddr2)<br>

<br>

monitor interval=60s (drbd1-monitor-interval-60s)<br>
Resource: shared_fs (class=ocf provider=heartbeat type=Filesystem)<br>

Operations: start interval=0s timeout=20 (PF-PEP-start-interval-0s)<br>
stop interval=0s timeout=20 (PF-PEP-stop-interval-0s)<br>
monitor interval=10 timeout=20 (PF-PEP-monitor-interval-10)<br>
Clone: supervisor-clone<br>
Resource: supervisor (class=ocf provider=pfpep type=pfpep_supervisor)<br>

stop interval=0s timeout=20 (supervisor-stop-interval-0s)<br>
monitor interval=10 timeout=20 (supervisor-monitor-interval-10)<br>
Clone: snmpAgent-clone<br>
Resource: snmpAgent (class=ocf provider=pfpep type=pfpep_snmpAgent)<br>
Operations: start interval=0s timeout=20 (snmpAgent-start-interval-0s)<br>
stop interval=0s timeout=20 (snmpAgent-stop-interval-0s)<br>
monitor interval=10 timeout=20 (snmpAgent-monitor-interval-10)<br>
<br>
Location Constraints:<br>
Resource: mda-ip<br>
Enabled on: MDA1PFP (score:50) (id:location-mda-ip-MDA1PFP-50)<br>
Ordering Constraints:<br>
promote drbd1_sync then start shared_fs (kind:Mandatory) (id:order-drbd1_sync-shared_fs-mandatory)<br>
start shared_fs then start PF-PEP (kind:Mandatory) (id:order-shared_fs-PF-PEP-mandatory)<br>
start snmpAgent-clone then start supervisor-clone (kind:Optional) (id:order-snmpAgent-clone-supervisor-clone-Optional)<br>
start shared_fs then start snmpAgent-clone (kind:Optional) (id:order-shared_fs-snmpAgent-clone-Optional)<br>
Colocation Constraints:<br>
mda-ip with drbd1_sync (score:INFINITY) (with-rsc-role:Master) (id:colocation-mda-ip-drbd1_sync-INFINITY)<br>
shared_fs with drbd1_sync (score:INFINITY) (with-rsc-role:Master) (id:colocation-shared_fs-drbd1_sync-INFINITY)<br>
PF-PEP with mda-ip (score:INFINITY) (id:colocation-PF-PEP-mda-ip-INFINITY)<br>
<br>
pcs resource defaults<br>
resource-stickiness: 100<br>
<br>
<div>I use the virtual IP as a master resource and colocate everyhting else with it. The resource prefers one node with a score of 50, and the stickiness is 100 so I expect that after switching to the passive node and activating the primary node again the resource
stays on the passive node. This works fine if I manually stop the primary node with pcs cluster stop. However, when I try to force a fail-over by unplugging the network cables of the primary node, and then after waiting plug in the cables again, the resource
moves back to the primary node.<br>
<br>
I tried larger stickiness values, and also to set a meta resource-stickiness property on the resource itself, but it did not change. How do configure this?<br>
<br>
Best wishes,<br>
Jens<br>
