[ceph-users] configure fuse in fstab

Hello Everyone! I'm trying to mount the ceph, with the fuse client under debian 9 (ceph-fuse 10.2.11-2). Ceph is on the latest Octopus release. The direct command is working, but writing it in fstab does not. Command I use: ceph-fuse --id dev.wsc -k /etc/ceph/ceph.clinet.dev.wsc.keyring -r /testing/dev.wsc/userdata /mnt/ceph /etc/ceph.conf: [global] fsid = [fsid] mon_host = 10.99.15.1 10.99.15.2 10.99.15.3 10.99.15.4 10.99.15.5 /etc/ceph/ceph.clinet.dev.wsc.keyring: [client.dev.wsc] key = [key] fstab: none /mnt/ceph fuse.ceph ceph.id=dev.wsc,ceph.conf=/etc/ceph/ceph.conf,ceph.client_mountpoint=/testing/dev.wsc/userdata,_netdev,defaults 0 0 With mount -a it tells me "ceph mount failed with (1) Operation not permitted". Where can I find authentication logs on the cluster? Thanks in advance and kind regards, Simon
