Hello,
Ceph is still not compiling when if I add Kinetic support option.
Could you have a look on the log and tell me what's missing ?

Hi,
Since firefly, ceph can support cache tiering.
Cache tiering: support for creating ‘cache pools’ that store hot, recently
accessed objects with automatic demotion of colder data to a base tier.
Typically the cache pool is backed by faster storage devices like SSDs.
I'm testing cache tiering,

Both fuse and kernel module fail to mount,
The mons mds are on two other nodes, so they are available when this node is
booting.
They can be mounted manually after boot.

Hmm, from a quick google it appears you are not the only one who has
seen this symptom with mount.ceph. Our mtab code appears to have
diverged a bit from the upstream util-linux repo, so it seems entirely
possible we have a bug in ours somewhere. I've opened
http://tracker.ceph.com/issues/10351
Can you tell us more about how they fail? Error messages on console,
anything in syslog?
In the absence of other clues, you might want to try checking that the
network is coming up before ceph tries to mount.

Cache tiering is a stable, functioning system. Those particular commands
are for testing and development purposes, not something you should run
(although they ought to be safe).

Hi,all
I found content below at
http://ceph.com/docs/master/rados/operations/crush-map :
step choose firstn {num} type {bucket-type}
Description: Selects the number of buckets of the given type. The
number is usually the number of replicas in the pool (i.e., pool size).
