I have selected the sync button and that is working. The speed is about 16000 kb/s wich is not so high. It takes 50h to complete.
But when the sync is starting the performance is realy bad. We have several terminal servers and when you login it takes 10 minutes to get in. Also the linux servers get a kernel panic. After the kernel panic i reboot the linux server but then they will not boot or it takes to long. I have shutdown the primary host and everything is working normal. I dont know what i can do now. Also i dont know how i can stop the sync. I have now shutdown the primary host otherwise he is starting the sync.
You can stop the Sync from the Volume Replication task, the sync needs to complete, make sure that the volume replication tasks is consistent to consistent for both Source and Destination in Status > Tasks, this is most likely the issue of your performance.
