about 10 - 30 ms of latency.

We have changed the IO scheduler to NOOP, which seems to yield the best
results. However, I haven’t look into messing around with tuned. Let me play
with that and see if I get different results.

To
size to 2 instead of 3. However this
isn’t much of a win for the purestorage which dedupes on the backend, so having
copies of data are relatively free for that unit. 1 wouldn’t work because this
is hosting a production work load.

So I’m trying to update the osd_op_threads setting that was in jewel, that now
doesn’t appear to be in luminous. What’s more confusing is that the docs state
that is a valid option. Is osd_op_threads still valid?
I’m currently running ceph 12.2.2

The first and hopefully easy one:
I have a situation where I have two pools that are rarely used (the third will
be in use after I can get through these issues), but they need to present at
the whims of our cloud team. Is there a way I can turn off ‘2 pools have many

another solution.
I have heard that BlueStore handles this better, but that wasn’t stable on the
release we are on.

Hallo Matthew,

Yeah, I don’t have access to the hypervisors, nor the vms on said hypervisors.
Having some sort of ceph-top would be awesome, I wish they would implement that.

When our clusters hits a failure (e.g. Node going down or osd dying) our vms
pause all IO for about 10 – 20 seconds. I’m curious if there is a way to fix or
mitigate this?
