After updating from 4.10 to 4.12 ceph became 100% used

Hi,

I am having the same issue however replacing monitor with the one from 14.10 did not resolve the issue for me.

When I run the monitor command from the logs I get the following result:

/usr/lib/ruby/1.8/rexml/parsers/treeparser.rb:92:in `parse': #<REXML::ParseException: #<NoMethodError: undefined    method `[]' for nil:NilClass> (REXML::ParseException)

Is there anything else you can advise?
