Update: setting "ceph fs set-default CEPH-FS-NAME" allows to do a kernel fs mount without providing the mds_namespace mount option, but the vfs_ceph module still fails with either cephwrap_connect: [CEPH] Error return: Operation not permitted or cephwrap_connect: [CEPH] Error return: Operation not supported depending on whether I use ceph:user_id = USER-NAME or ceph:user_id = client.USER-NAME I guess the second user spec is correct as the first error message indicates an auth problem. On the client side I see the same message in both cases: tree connect failed: NT_STATUS_UNSUCCESSFUL Best regards, ================= Frank Schilder AIT Risø Campus Bygning 109, rum S14 ________________________________________ From: Frank Schilder <frans@xxxxxx> Sent: 23 September 2020 11:00:50 To: ceph-users Subject: samba vfs_ceph: client_mds_namespace not working? Dear all, maybe someone has experienced this before. We are setting up a SAMBA gateway and would like to use the vfs_ceph module. In case of several file systems one needs to choose an mds namespace. There is an option in ceph.conf: client mds namespace = CEPH-FS-NAME Unfortunately, it seems not to work. I tried it in all possible versions, in [global] and [client], with and without "client" at the beginning, to no avail. I either get a time out or an error. I also found the libcephfs function ceph_select_filesystem(cmount, CEPH-FS-NAME) added it to vfs_ceph.c just before the ceph_mount with the same result, I get an error (operation not permitted). Does anyone know how to get this to work? And, yes, I tested an ordinary kernel fs mount with the credentials for the ceph client without problems. I can't access any documentation on the libcephfs api, I always get a page not found error. My last resort is now to ceph fs set-default CEPH-FS-NAME to the fs to be used and live with the implied restrictions and ugliness.
