Hello all,
we're currently testing a 2-node-cluster 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.
Live migration works, if we issue "pcs resource move ...", "pcs
cluster standby", "pcs cluster stop" and even "systemctl rescue".
The latter only worked, after adding the following additional
dependencies to pacemaker.service and leaving the management of those
services to systemd:
* After/Requires=systemd-machined.service
* After/Requires=systemd-machine-id-commit.service
* After/Requires=remote-fs.target
* After/Requires=libvirtd.service
* After/Requires=iscsi.service
* After/Requires=iscsid.service
* After/Requires=sshd.service
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.
Is this a known issue? Did we miss any further dependencies?
