Are you supposed to be able to relocate service data with OS X ML Server?

same problem, impossible for me to move the server data to a new drive.

I can select the drive. but when clicking ok to accept the move, nothing happens and the message box stays on top. Clicking on Cancel has no effect too. I have to quit the server.app to make it disappear.

All ideas are welcome !

I get the following error in the log :

Same problem.

Did you guys use Migration Assistant? When you did, was the service data already on an external volume?

If so:

Service Data

In most cases, your service data and settings will be preserved completely when upgrading or migrating. See below for exceptions or special instructions before you upgrade or migrate your server.

Service data that is stored in the default location in Lion Server or Snow Leopard Server will be moved to the new default service data location inside /Library/Server/. Service data stored in a alternate location will remain in the alternate location.

Note: If you selected an alternate data storage location in Lion Server, only those services that used the alternate location in Lion will use it in Mountain Lion. Other services will use the default location and you cannot relocate them to the alternate location.

I have a brand new Mac Mini Server that had Lion Server on it. I used Apple Up To Date to get Mountain Lion, then Mtn Lion Server on it. We just added a Promise 4TB Thunderbolt array, and when I try to move the service data, I get this same thing. I can hit OK a thousand times, and nothing happens - the Are you sure message stays on the screen. I can click cancel, and it ignores that as well.

Activity monitor shows no spikes in disk activity, so it's not copying (there is only 12GB on the whole drive anyway).

Logged in as local administrator.

Yes I am getting the same error.

The Mac Mini was originally a Lion Server, all settings (including Service Data) were configured using the defaults provided by apple. And now that it is upgraded to Mountain Lion and now that I have a RAID 10 array I want to move the service data, but I get the same unresponsive confirmation window. I could Click on OK a million times and it won't do anything, and even if I click cancel a million times it remains on display and completely unresponsive.

Devs you need to look into the Service Data Migration confirmation dialog, because it should at least have some sort of time-out or error, but something is not being caught in the app and there is no proper handling of the error.

I have the same issue. After click on OK, i can't exit the confirmation window. I had to quit server.app

I have exactly the same problem. I updated my home server from Snow Leopard -- with servicedata already relocated to a second drive -- to Mountain Lion server.

Despite this, most of the services are on the boot drive. Attempting to move them are recommend in the Apple Technote results in the process never finishing, and the sheet staying stuck on the screen.

Seems to me like it's broken. Badly.
