[ceph-users] 4.14 kernel or greater recommendation for multiple active MDS

In the Nautilus manual it recommends >= 4.14 kernel for multiple active MDSes. What are the potential issues for running the 4.4 kernel with multiple MDSes? We are in the process of upgrading the clients, but at times overrun the capacity of a single MDS server. MULTIPLE ACTIVE METADATA SERVERS <https://docs.ceph.com/docs/nautilus/cephfs/kernel-features/#multiple-active-metadata-servers> The feature has been supported since the Luminous release. It is recommended to use Linux kernel clients >= 4.14 when there are multiple active MDS.
