I don't think this is documented specifically; you'd have to go through the git logs. Talked with the team and 4.14 was the upstream kernel when we marked multi-MDS as stable, with the general stream of ongoing fixes that always applies there. There aren't any known issues that will cause file consistency to break or anything; I'd be more worried about clients having issues reconnecting when their network blips or an MDS fails over. -Greg > > 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.
