[PVE-User] Ceph Cache tiering

[gauthierl]

Hi,

We was interested by setup a SSD cache tiering for our RBD storage but in the CEPH documentation, it seems to not recommend it :
http://docs.ceph.com/docs/master/rados/operations/cache-tiering/?highlight=tier#known-bad-workloads

Has any one have experience with it ?

Sadly I can't answer this one.

We use SSDs for OSD journals and the pveceph tool is working well with it, also from the GUI.
