Hi All, I was checking the operation of Bundle with Pacemaker version 2.0.0-9cd0f6cb86. When Bundle resource is configured in Pacemaker and attribute is changed, pengine core dumps. Step1) Start Pacemaker and pour in the settings. (The replicas and replicas-per-host are set to 1.) [root@rh74-test ~]# cibadmin --modify --allow-create --scope resources -X ' <bundle id="httpd-bundle"> <docker image="pcmktest:http" replicas="1" replicas-per-host="1" options="--log-driver=journald" /> <network ip-range-start="192.168.20.188" host-interface="ens192" host-netmask="24"> <port-mapping id="httpd-port" port="80"/> </network> <storage> <storage-mapping id="httpd-root" source-dir-root="/var/local/containers" target-dir="/var/www/html" options="rw"/> <storage-mapping id="httpd-logs" source-dir-root="/var/log/pacemaker/bundles" target-dir="/etc/httpd/logs" options="rw"/> </storage> <primitive class="ocf" id="httpd" provider="heartbeat" type="apache" > <operations> <op id="rabbitmq-monitor-interval-10" interval="10" name="monitor" timeout="40"/> <op id="rabbitmq-start-interval-0s" interval="0s" name="start" timeout="200s"/> <op id="rabbitmq-stop-interval-0s" interval="0s" name="stop" timeout="200s" on-fail="fence" /> </operations> </primitive> ' Step2) Bundle is configured.

Apparently the problem seems to be due to different handling of clone(httpd) resources in the Bundle resource.
