Hi again, I'm trying to write a systemd-script (for CentOS7) in order to automatically put the host in "maintenance" on shutdown and to activate it after boot. I wrote a python-script that to that and it works so that I can start it and see the host in "maintenance" and having all VMs migrated. Unfortunately I can't call this script on shutdown/reboot and wait until all VMs are migrated and the host is in maintenance. Here my script: [Unit] Description=oVirt interface for managing host After=remote-fs.target vdsmd.service multipathd.service libvirtd.service time-sync.target iscsid.service rpcbind.service supervdsmd.service sanlock.service vdsm-network.service Wants=remote-fs.target vdsmd.service multipathd.service libvirtd.service time-sync.target iscsid.service rpcbind.service supervdsmd.service sanlock.service vdsm-network.service [Service] Type=simple RemainAfterExit=yes ExecStart=/usr/local/bin/ovirt-maintenance.sh active ExecStop=/usr/local/bin/ovirt-maintenance.sh maintenance KillMode=none [Install] WantedBy=multi-user.target Could someone help me and say what I'm doing wrong?
