That was not my question.
The whole point of my posting was: it does not get the same IP, not sure how
you missed it.
If you took a look into /usr/lib/ocf/resource.d/heartbeat/IPaddr2, you would see
case "$OCF_RESKEY_unique_clone_address" in
true|TRUE|True|yes|YES|Yes|1)
prefix=`echo $OCF_RESKEY_ip | awk -F. '{print $1"."$2"."$3}'`
suffix=`echo $OCF_RESKEY_ip | awk -F. '{print $4}'`
suffix=`expr ${OCF_RESKEY_CRM_meta_clone:-0} + $suffix`
OCF_RESKEY_ip="$prefix.$suffix"
;;
*) ;;
esac
And again, my posting clearly showed configured ip 10.10.10.22 versus assigned
- 10.10.10.23.
