Hello, When trying to put one of our OSD hosts in maintenance, "ceph orch host maintenance enter” displays: WARNING: Removing NFS daemons can cause clients to lose connectivity.
We have a single Cephfs filesystem in our cluster. Five hosts are “admin” hosts that run cephadm, mds, mgr, mon, etc. The rests of our hosts are OSDs with the spinning disks that make up our Cephfs data pool. Our current setup follows the "HIGH-AVAILABILITY NFS” documentation, which gives us an Ingress.nfs.cephfs service with the haproxy and keepalived daemons and a nfs.cephfs service for the actual nfs daemons. This service was deployed using: ceph nfs cluster create cephfs "label:_admin" --ingress --virtual_ip virtual_ip And then we manually updated the nfs.cephfs service this created to place the nfs daemons on our OSD nodes. This gives us the following: ——— service_type: ingress service_id: nfs.cephfs service_name: ingress.nfs.cephfs placement: label: _admin spec: backend_service: nfs.cephfs first_virtual_router_id: 50 frontend_port: 2049 monitor_port: 9049 virtual_ip: virtual_ip/prefix service_type: nfs service_id: cephfs service_name: nfs.cephfs placement: label: osd spec: port: 12049 ——— How can we safely put one of our osd nodes in maintenance? Or is there a better way to organize our daemons or setup and manage our NFS service that would avoid this issue?
