ah OK  - thanks that's it - ceph has now also recovered completely with 
old crushmap.

OK now back to my original problem.

i wanted to change from this:
-----------------------------------------
...

rack D2-switchA {
         id -100         # do not change unnecessarily
         # weight 12.000
         alg straw
         hash 0  # rjenkins1
         item server1263 weight 4.000
         item server1264 weight 4.000
         item server1265 weight 4.000
}
rack D2-switchB {
         id -101         # do not change unnecessarily
         # weight 12.000
         alg straw
         hash 0  # rjenkins1
         item server1266 weight 4.000
         item server1267 weight 4.000
         item server1268 weight 4.000
}
root root {
         id -10000               # do not change unnecessarily
         # weight 24.000
         alg straw
         hash 0  # rjenkins1
         item D2-switchA weight 12.000
         item D2-switchB weight 12.000
}

...
-----------------------------------------

to this one:

-----------------------------------------
...

rack D2 {
         id -100         # do not change unnecessarily
         # weight 24.000
         alg straw
         hash 0  # rjenkins1
         item cloud1-1263 weight 4.000
         item cloud1-1264 weight 4.000
         item cloud1-1265 weight 4.000
         item cloud1-1266 weight 4.000
         item cloud1-1267 weight 4.000
         item cloud1-1268 weight 4.000
}
root root {
         id -10000               # do not change unnecessarily
         # weight 24.000
         alg straw
         hash 0  # rjenkins1
         item D2 weight 24.000
}

...

This was where all problems started. Is this wrong? / not possible?
