logs from monitor node with calamari

Description of problem:
I've tried to create erasure-coded pool in USM. Calamari task has failed(/var/log/calamari/cthulhu.log):
2016-05-25 01:52:21,818 - ERROR - calamari.request_collection Request 92cf45c6-db36-40ad-b2b2-3cffe6c6b28c experienced an error: can not change the size of an erasure-coded pool
2016-05-25 01:52:21,818 - ERROR - calamari.request_collection Request 92cf45c6-db36-40ad-b2b2-3cffe6c6b28c experienced an error: can not change the size of an erasure-coded pool

But it seems that pool has been created:
$ ceph -c /etc/ceph/testcluster.conf osd pool ls detail
pool 1 'testpool' replicated size 3 min_size 2 crush_ruleset 0 object_hash rjenkins pg_num 128 pgp_num 128 last_change 33 flags hashpspool stripe_width 0
	removed_snaps [1~3]
--> pool 2 'test2pool' erasure size 3 min_size 2 crush_ruleset 1 object_hash rjenkins pg_num 128 pgp_num 128 last_change 35 flags hashpspool stripe_width 4096

$ ceph -c /etc/ceph/testcluster.conf osd pool stats
pool testpool id 1
  nothing is going on

--> pool test2pool id 2
      nothing is going on

Version-Release number of selected component (if applicable):

python-cephfs-10.2.1-6.el7cp.x86_64
rhscon-agent-0.0.8-1.el7scon.noarch

Steps to Reproduce:
1. install USM
2. create cluster
3. try to create erasure-coded pool

Actual results:
Calamari reports error but pool is created and according ceph commands also in good state.
