[systemd-devel] Fwd: systemd: wait for shutdown-service to complete

[Reindl Harald]

there must be some bug in Fedora 15 systemd
"systectl start/stop vmware-default.service" works perfectly

but at shutdown systemd will not wait until it is finished
before the sysv-service "vmware-service" is terminated
what results in hard-powered-off guests and fschecks in most
guests starting the host the next time :-(

[root at rh:~]$ cat /etc/systemd/system/vmware-default.service
[Unit]
Description=VMware-Default-Machines
After=vmware.service
[Service]
Type=oneshot
ExecStart=/bin/su -c "/scripts/vmware/vm-default-start.sh" vmware
ExecStop=/scripts/vmware/vm-suspend-all.sh
RemainAfterExit=yes
TimeoutSec=600
SysVStartPriority=90
[Install]
WantedBy=multi-user.target


[root at rh:~]$ cat /scripts/vmware/vm-suspend-all.sh
#!/bin/bash
if [ -x /usr/bin/vmrun ] ; then
 for i in `pidof vmware-vmx` ; do
  VMX_PATH=`ps -p $i -f | sed -ne '/vmware/s/.* \(\/.*\.vmx\)/\1/p'`
  MY_DATE=$(/bin/date +%d-%m-%Y)
  MY_TIME=$(/bin/date +%H:%M:%S)
  echo "$MY_DATE $MY_TIME  SUSPEND: $VMX_PATH"
  /usr/bin/logger -t vmware "SUSPEND: $VMX_PATH"
  /usr/bin/vmrun suspend `ps -p $i -f | sed -ne '/vmware/s/.* \(\/.*\.vmx\)/\1/p'` 2> /dev/null
  MY_DATE=$(/bin/date +%d-%m-%Y)
  MY_TIME=$(/bin/date +%H:%M:%S)
  echo "$MY_DATE $MY_TIME  SUSPENDED: $VMX_PATH"
  /usr/bin/logger -t vmware "SUSPENDED: $VMX_PATH"
 done
fi


[root at rh:~]$ cat /scripts/vmware/vm-default-start.sh
#!/bin/bash
if [ "$HOSTNAME" == "srv-rhsoft.rhsoft.net" ]; then
 /usr/bin/vmrun -T ws start '/mnt/data/fileserver/vmware/arrakis/arrakis.vmx' nogui

that was my idea for this "fake-service"

sounds reasonable
