Hi Don, after a lot of trouble due an unfinished setcrushmap, I was able to remove the new EC pool. Load the old crushmap and edit agin. After include an "step set_choose_tries 100" in the crushmap the EC pool creation with ceph osd pool create ec7archiv 1024 1024 erasure 7hostprofile work without trouble.
Due to defect PGs from this test, I remove the cache tier from the old EC pool which gaves the next trouble - but this is another story!
