Hi,

It's just like NFS, if you mount an NFS export on the NFS server, you get
kernel locks.

Unfortunately even if love Ceph far more than the other, I won't go with
CephFS, at least not know. But if are in a hurry and looking for a DFS then
GlusterFS seems to be a good candidate. NFS works pretty well too.

Cheers.
