It looks like the libvirt (2.0.0-10.el7_3.2) that ships with centos 7.3 is
broken out of the box when it comes to hot plugging new virtio-scsi devices
backed by rbd and cephx auth. If you use openstack, cephx auth, and centos,
I’d caution against the upgrade to centos 7.3 right now.

twice to get to something from the 1.2 series.

Hi,
Happy New Year!
Can anyone point me to specific walkthrough / howto instructions how to
move cephfs metadata to SSD in a running cluster?
How is crush to be modified step by step such that the metadata migrate
to SSD?
Thanks and regards,
Mike
will metadata on SSD improve latency significantly?

I've never done migration of cephfs_metadata from spindle disks to

Wido, all,
can you point me to the "recent benchmarks" so I can have a look?
How do you define "performance"? I would not expect cephFS throughput to
change, but it is surprising to me that metadata on SSD will have no
measurable effect on latency.

with the OpenStack Foundation in providing a Ceph
Day at the same venue that the OpenStack Summit will be taking place. You do
need to purchase a Ceph Day pass even if you have a Full access pass for the
OpenStack summit.

Hi Nitin,
I'm still receiving slides from the speakers but I think I will start posting
them tomorrow. I will reply back when this is done. Thanks!

I’m sorry I completely missed the text you wrote at the top of the reply. It at
first appeared that you just quoted a previous reply without adding.
My mistake!
Thank you for the answer as it completely correlates with what I've found after
doing some other digging.
Cheers,
