Hello Loic,
You ask previously:
In other words, is there a place where one could set things like disk
fail % of the time and network is X Gb/s and repairing a disk
failure requires disk require reading B bytes from M disks ? As far
as I understand, such factors cannot be expressed with a single

Hi all,
What about the following usecase (please forgive some of my ceph
architecture ignorance):
If it was possible to setup OSD caching tier at the host (if the host
had a dedicated SSD for accelerating I/O), then caching pools could be
created to cache VM rbds, since they are inherently exclusive

Kind of unrelated to the rest of the series, but it looks
good. Good to have a same-level-of-abstraction function
