<p>Hello all,<br>
<br>
we're currently testing a 2-node<span class="spellcheckIncorrect" index="12">-</span><span class="spellcheckIncorrect" index="22">cluster</span> with 2 vms and live migration on CentOS 7.2 and Pacemaker 1.1.13-10 with disks on iSCSI-targets and migration via ssh-method.<br>
<br>
Live migration works, if we issue "pcs resource move ...", "pcs cluster standby", "pcs cluster stop" and even "systemctl rescue".<br>
The latter only worked, after adding the following additional dependencies to pacemaker.service and leaving the management of those services to systemd:</p>
<ul>
<li>After/Requires=systemd-machined.service</li>
<li>After/Requires=systemd-machine-id-commit.service</li>
<li>After/Requires=remote-fs.target</li>
<li>After/Requires=libvirtd.service</li>
<li>After/Requires=iscsi.service</li>
<li>After/Requires=iscsid.service</li>
<li>After/Requires=sshd.service</li>
</ul>
<p>When shutting down or rebooting migration fails and not even the regular shutdown of the vms succeeds. Systemd seems to tear down the vms by terminating something they depend on.<br>
<br>
Is this a known issue? Did we miss any further dependencies?<br>
<br>
