Do both. Host striping will give you more queues, RBD striping will use
more OSDs.

Because you only assigned 1 volume (sdb), you will be limited to a
single queue. I'd recommend adding more volumes

HI all!
I use ceph as the openstack VM disk. I have a VM run postgresql.
I found the disk on the vm run postgresql is very busy and slow!
But the ceph cluster is very healthy and without any slow request.
Even the vm disk is very busy, but the ceph cluster is look like very idle.
My cep
So can you do it.
Yes you can.
Should you do it is the bigger question.
So my first question would be what type of drives are you using? Enterprise
class drives with a low failure rate?
Then you have to ask yourself are you feeling lucky?
If you do a scrub and 1 drive returns 1 value and anot

We have all SSD disks as ceph's backend storage.
Consider the cost factor, can we setup the cluster to have only two

thanks & regards

Looking at the documentation, solving the overload problem might require some
QoS settings I found below the description of "osd op
Same set-up as Robert. Two different VLANs for front and back network on same
switch. We did load tests before and the switches have no problems routing the
traffic.
