Hi folks,
So I was having some back and forth internally about is cinder ready for
usage and wanted to get other operators thoughts on how there cinder
experiences have been going, any trials and tribulations.
For context, we are running on liberty (yes I know, working on getting
that to newer versions) and folks in godaddy are starting to use more
and more cinder (backed by ceph) and that got me thinking about asking
the question from operators (and devs) on what kind of readiness
'rating' (or whatever you would want to call it) would people give
cinder in liberty.
Some things that I was thinking was around concurrency rates, because I
know that's be a common issue that the cinder developers have been
working through (using tooz, and various other lock mechanisms and such).
Have other cinder operators seen concurrent operations (or conflicting
operations or ...) work better in newer releases (is there any metric/s
anyone has gathered about how things have gotten worse/better under
scale for cinder in various releases? partically with regard to using ceph).
Thoughts?
It'd be interesting to capture (not just for my own usage) I think
because such info helps the overall user and operator and dev community
(and yes I would expect various etherpads to have parts of this
information, but it'd be nice to have like a single place where other
operators can specify how ready they believe a project is for a given
release and for a given configuration; and ideally provide
details/comments as to why they believe this).
