Description Lubos Trilety 2016-06-03 11:13:24 UTC 
Description of problem:
During RBD creation it's possible to choose EC pool as the one on which the rados block device will be. It will fail because ceph does not support this. However UI should not offer creating RBD on EC pool at all.

Version-Release number of selected component (if applicable):
rhscon-ui-0.0.34-1.el7scon.noarch
rhscon-ceph-0.0.20-1.el7scon.x86_64
rhscon-core-0.0.21-1.el7scon.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Create some EC pool
2. Try to create rados block device

Actual results:
It's possible to choose created EC pool as the one on which the RBD should be. Moreover if an option about creating a new pool is checked, it's possible to choose that an EC pool should be created.

Expected results:
RBD creation should not offer any EC pool.

Comment 1 Ju Lim 2016-06-07 18:45:36 UTC 
Looks like this is a matter of not exposing pools that are erasure coded in the existing pools selection, and only showing the standard/replicated pools.
Comment 2 Martin Bukatovic 2016-06-29 17:02:46 UTC 
Created attachment 1174054 [details]
screenshot of "Add Block Storage" page

Checking with:

~~~
# rpm -qa rhscon*
rhscon-ui-0.0.42-1.el7scon.noarch
rhscon-core-0.0.28-1.el7scon.x86_64
rhscon-ceph-0.0.27-1.el7scon.x86_64
rhscon-core-selinux-0.0.28-1.el7scon.noarch
~~~

And I see that Erasure Coded type is still available in "Add Block Storage"
wizard when one selects "Create new pool".

=> MODIFIED
Comment 3 Martin Bukatovic 2016-06-29 17:04:35 UTC 
grep 's/MODIFIED/ASSIGNED/' comment 2

Setting this BZ back into ASSIGNED state based on verification fail as explained
in comment 2.
Comment 4 Martin Bukatovic 2016-07-15 16:23:27 UTC 
Testing with: rhscon-ui-0.0.48-1.el7scon.noarch

I see no change compared to rhscon-ui-0.0.42-1.el7scon.noarch (as described in
comment 2): I can still select EC pool with "Create new pool" RBD option.

Moving back to MODIFIED
Comment 5 Martin Bukatovic 2016-07-15 16:26:32 UTC 
ah, grep 's/MODIFIED/ASSIGNED/' (again)
Comment 6 Martin Kudlej 2016-08-04 12:34:01 UTC 
Tested with
ceph-ansible-1.0.5-31.el7scon.noarch
ceph-installer-1.0.14-1.el7scon.noarch
rhscon-ceph-0.0.39-1.el7scon.x86_64
rhscon-core-0.0.39-1.el7scon.x86_64
rhscon-core-selinux-0.0.39-1.el7scon.noarch
rhscon-ui-0.0.51-1.el7scon.noarch
and it works.
