Hi Ulrich,
What would I need to change?
pcs resource meta resourcedrbdClone resource-stickiness=0
doesn't fix it.
I already have:
#> pcs property list --all | grep stick
default-resource-stickiness: (null)
#> pcs resource defaults
No defaults set
Thanks,
Alastair.

My guess is default stickiness being > 0.

Hi all,
Some help required with master/slave moving please...
I have set up a resource with:
pcs resource create resourcedrbd ocf:linbit:drbd drbd_resource=disk1 op
monitor interval=60s
pcs resource master resourcedrbdClne resourcedrbd master‑max=1
master‑node‑max=1 clone‑max=2 clone‑node‑max=1 notify=true
pcs constraint location resourcedrbdClone prefers node1=100
pcs constraint location resourcedrbdClone prefers node1=50
pcs constraint location resourcedrbdClone avoids node3
pcs constraint location resourcedrbdClone avoids node4
pcs resource op add resourcedrbd monitor interval=61s role=Master
pcs constraint location resourcedrbdClone rule role=master score=100 \#uname
eq node1
pcs constraint location resourcedrbdClone rule role=master score=50 \#uname
eq node2
If I put node1 into standby:
pcs cluster standby node1
It works, and moves the resource to node2.
However, when I bring it back:
pcs cluster unstandby node1
the resource remains on node2.
I want the resource to move back to node1.
What have I missed? I thought the location rule should have sorted this
out.
I have also tried:
pcs constraint rule add location‑resourcedrbdClone‑1 role=master score=100
\#uname eq node1
(getting the location‑resourcedrbdClone‑1 ID from
/var/lib/pacemaker/cib/cib.xml ‑ though I guess there might be a better
way to get the ID through pcs)
And this doesn't help.
Thanks,
Alastair.
