Hi,
I am currently working on a replication solution adding logic to the
mysql RA and I need to be able to turn ON/OFF a virtual IP based on a
node attribute (Florian suggestion). In order to achieve this, I
created a clone set of IPaddr2 RA and a location rule using the node
attribute setting. It works almost correctly except that clone members
stick a bit too much and don't failback. Here's my config:
node testvirtbox1 \
attributes IP="10.2.2.160"
node testvirtbox2 \
attributes IP="10.2.2.161" \
attributes standby="off"
node testvirtbox3 \
attributes IP="10.2.2.162" \
attributes standby="off"
primitive reader_vip_1 ocf:heartbeat:IPaddr2 \
params ip="10.2.2.171" nic="eth0"
clone reader_vips reader_vip_1 \
meta globally-unique="true" clone-max="3" clone-node-max="3"
notify="true" ordered="true" interleave="true"
location No-reader-vip-loc reader_vips \
rule $id="No-reader-vip-rule" -inf: readerOK eq 0
colocation reader_vips_dislike_reader_vips -200: reader_vips reader_vips
property $id="cib-bootstrap-options" \
dc-version="1.0.11-a15ead49e20f047e129882619ed075a65c1ebdfe" \
cluster-infrastructure="openais" \
expected-quorum-votes="3" \
stonith-enabled="false" \
no-quorum-policy="ignore"
rsc_defaults $id="rsc-options" \
resource-stickiness="100"
- Upon startup, the reader_vips clone are well spread on all 3 nodes
- Running "crm_attribute -N testvirtbox1 -l reboot --name readerOK -s
mysql_replication -v '0'" removes the clone set member from
testvirtbox1 as expected and add it to testvirtbox2 or testvirtbox3
- But... running "crm_attribute -N testvirtbox1 -l reboot --name
readerOK -s mysql_replication -v '1'" does not make it come back, one of
the other node still have 2 clone members
Is there a way to make it come back normally or is there something I
don't do correctly?
Regards,
Yves
