Works like expected.

The one big problem I had previously with MDS not being ready is gone as one can see now in the task log, that it is waiting for the MDS to become active before continuing.

Tested the removal procedure outlined in the docs patch and as long as the storage is still active, it gives a nice warning.

Of course, being lazy I did not unmount it on all the nodes first and once it is removed, the nodes and child items all show question marks in the tree view. Once it gets unmounted with -f -l (force & lazy) parameters, the nodes are shown as okay again in the GUI.

Not sure if we want to check against it not being mounted on all nodes before proceeding or if that is the responsibility of the admin.
