Wow, it's something new. What is your upgrade path?


I keep current with community.  All osds have all been rebuilt as of luminous.

 
Also, you record cluster metrics, like via prometheus? To see diff

Unfortunately not.  I've only had prometheus running for about two weeks aaaand I had it turned off for a couple days for some unknown reason... :/

This is sad. Because it's was be good to see the nature of metrics on graph.
