Hi,
we are about to setup a new Ceph cluster for our Openstack cloud. Ceph
is used for images, volumes and object storage. I'm unsure to handle
these cases and how to move the data correctly.

I consider this the easiest case, since RGW itself provides the

Hi,
If you run "rbd snap ls --all", you should see a snapshot in
the "trash" namespace.
I just tried the command "rbd snap ls --all" on a lab cluster
(nautilus) and get this error:
ceph-2:~ # rbd snap ls --all
rbd: image name was not specified
Are there any requirements I haven't noticed?

Sorry -- you need the "" as part of that command.
My bad, I only read this from the help page ignoring the
(and forgot the pool name):
-a [ --all ] list snapshots from all namespaces
I figured this would list all existing snapshots, similar to the "rbd

Hello,
I haven't had any issues either with 4k allocation size in cluster

This is an average of 324k per object and 12.6M of chunks/replicas per

Oh no! We have activated inline_data since our cluster does have lots of small

This also happened sometimes during a Luminous -> Mimic upgrade due to
a bug in Luminous; however I thought it was fixed on the ceph-mgr

Maybe the fix was (also) required in the OSDs and you are seeing this
because the running OSDs have that bug?
Anyways, it's harmless and you can ignore it.

Hello Ceph Users,
I am finding that the write latency across my ceph clusters isn't great and I
wanted to see what other people are getting for op_w_latency. Generally I am
getting 70-110ms latency.
