Hi Stefan,
sorry, forgot. Block device is almost certainly LVM with dmcrypt - unless you have
another way of using encryption with ceph OSDs.
I can compare LVM with LVM+dmcrypt(default/new) and possibly also raw /dev/sd?
performance. If LVM+dmcrypt shows good results, I will also try it with our test cluster.
We use it with OSDs prepared with ceph-volume. Do you use ceph-volume?
So in this case the logical volume (LV) is encrypted and used by ceph.
