Fixed In Version: ceph-ansible-2.1.7-1.el7scon Doc Type: Bug Fix
Doc Text:
Previously, during the creation of Ceph clusters with nodes that use IPv6 addressing, ceph-ansible added the "ms bind ipv6" key to the Ceph configuration file, but it did not assign any value to it. This behavior caused an error when parsing the configuration file after the cluster creation. With this update, the "ms bind ipv6" key is properly set in the Ceph configuration file allowing for proper configuration file parsing on clusters that use IPv6 addressing.

Version-Release number of selected component (if applicable):
10.2.5-21

How reproducible:
Always

Steps to Reproduce:
1. Create a cluster of ipv6 machines.
2. Run any ceph commands

Actual results:

$sudo ceph osd tree --cluster 2_2_on_7_3

Comment 5 Vasishta 2017-02-07 09:12:11 UTC 
Description -
During creation of cluster with ipv6 nodes, 'ms bind ipv6' key is getting added in the configuration file without getting assigned any value. This creates error while parsing the config file after cluster creation. 

version: ceph-ansible-2.1.6-1.el7scon.noarch
Comment 7 Andrew Schoen 2017-02-07 18:39:16 UTC 
PR opened upstream: https://github.com/ceph/ceph-ansible/pull/1285
Comment 8 seb 2017-02-08 15:27:06 UTC 
This will be fixed upstream with the tag 2.1.7 which will likely appear as ceph-ansible-2.1.7-1.el7scon.noarch downstream soon.
