Hi, it's been a while since im using Ceph, and still im a little

Hi everyone!
I have to install a ceph cluster (6 nodes) with two "flavors" of
disks, 3 servers with SSD and 3 servers with SATA.
Y will purchase 24 disks servers (the ones with sata with NVE SSD for
the SATA journal)
Processors will be 2 x E5-2620v4 with HT, and ram will be 20GB for the
OS, and 1.
ournal you could generate up to 250MB/s of traffic per SSD OSD (24Gbps for
> 12x or 48Gbps for 24x) therefore I would consider doing 4x10G and

Guys hi.
I have a Jewel Cluster divided into two racks which is configured on
the crush map.
I have clients (openstack compute nodes) that are closer from one rack
than to another.
I would love to (if is possible) to specify in some way the clients to
read first from the nodes on a specific rack t
any experiences ?

Peter, hi ... what happened to me is exactly what happened to you,
thanks so much for pointing that out!
I'm amazed on how you realized that was the problem !!
Maybe that will help me troubleshoot a little more pro.

you might want to configure cinder.conf with
verbose = true
debug = true
and see /var/log/cinder/cinder-volume.log after a "systemctl restart
cinder-volume" to see the real cause.
