Hi David,I am using Samba 4.6.7 (shipped with Ubuntu 17.10). I've got it working now by copying the ceph.client.admin.keyring to /etc/ceph (I'm very unhappy with that). Which Samba Version & Linux Distribution are using? Are you using quotas on subdirectories and are they applied when you export the subdirectory via samba?

Which version of Samba are you using? Make sure it includes the fix for https://bugzilla.samba.org/show_bug.cgi?id=12911 .We are running ceph jewel with cephx enabled. Manpage of vfs_ceph only references the option ceph:config_file. How do I need to configure my share (or maybe ceph.conf)? log.smbd: '/' does not exist or permission denied when connecting to [vfs] Error was Transport endpoint is not connected I have a user ctdb with keyring file /etc/ceph/ceph.client.ctdb.keyring with permissions: caps: [mds] allow rw caps: [mon] allow r caps: [osd] allow rwx pool=cephfs_metadata,allow rwx pool=cephfs_data I can mount cephfs with cephf-fuse using the id ctdb and its keyfile. My share definition is: [vfs] comment = vfs path = / read only = No vfs objects = acl_xattr ceph ceph:user_id = ctdb ceph:config_file = /etc/ceph/ceph.confYour configuration looks fine - can you confirm that the *mapped* Samba user is permitted access to the root of the CephFS filesystem? Have you tried using ceph-fuse as the mapped user? If you're still running into problems, feel free to raise a ticket at bugzilla.samba.org and assign it to me. Cheers, David
