Hi, As http://docs.ceph.com/docs/master/cephfs/nfs/ says, it's OK to config active/passive NFS-Ganesha to use CephFs. My question is if we can use active/active nfs-ganesha for CephFS. In my thought, only state consistance should we think about. 1. Lock support for Active/Active. Even each nfs-ganesha sever mantain the lock state, the real lock/unlock will call ceph_ll_getlk/ceph_ll_setlk. So Ceph cluster will handle the lock safely. 2. Delegation support Active/Active. It's similar question 1, ceph_ll_delegation will handle it safely. 3. Nfs-ganesha cache support Active/Active. As https://github.com/nfs-ganesha/nfs-ganesha/blob/next/src/config_samples/ceph.conf describes, we can config cache size as size 1. 4. Ceph-FSAL cache support Active/Active. Like other CephFs client, there is no issues for cache consistance.
