I would like to (in this order)
- set the data pool for the root "/" of a ceph-fs to a custom value, say "P" (not the initial data pool used in fs new)
- create a sub-directory of "/", for example "/a"
- mount the sub-directory "/a" with a client key with access restricted to "/a"
The client will not be able to see the dir layout attribute set at "/", its not mounted.
Will the data of this client still go to the pool "P", that is, does "/a" inherit the dir layout transparently to the client when following the steps above?
AFAIU:
"/" (the cephfs root) is "pool_A"
"/folder" is "pool_B"
If you want for your client to put data to "/folder" only, you should
set "caps: [mds] allow rw path=/folder"
and yes, client data will be putted to "pool_B".
