I have a ceph filesystem I'm trying to export using nfs ganesha. Ceph indicates that the cluster is fine: ceph status cluster: id: 108a355b-1e9b-493d-91a0-ab898a67aa51 health: HEALTH_OK ... mds: cephfs:1 {0=unique=up:active} But when I try to mount the filesystem over nfs with nfs ganesha I get: $ mount -t nfs -o nfsvers=4.1,noauto,soft,sync localhost:/ test $ touch test/i touch: cannot touch ‘test/i’: Read-only file system And there are errors in ganesha.log Anything obvious wrong with my configuration? { Export_Id = 25; Path = "/"; Pseudo = "/"; Access_Type = RW; Protocols = 4; Transports = TCP; SecType = sys; Squash = No_Root_Squash; FSAL { Name = "CEPH"; Filesystem = "cephfs"; User_Id = "testuser"; Secret_Access_Key = "<removed secret for post>"; } } CEPH { Ceph_Conf = "/etc/ceph/ceph.conf"; } 26/08/2021 02:24:34 : epoch 6126fb62 :
