Hi, A little basic question. I created a volume with ceph fs volume then a subvolume called «erasure» I can see that with root@cthulhu1:/etc/ceph# ceph fs subvolume info cephfs erasure { "atime": "2024-02-02 11:02:07", "bytes_pcent": "undefined", "bytes_quota": "infinite", "bytes_used": 0, "created_at": "2024-02-02 11:02:07", "ctime": "2024-02-02 14:12:30", "data_pool": "data_ec", "features": [ "snapshot-clone", "snapshot-autoprotect", "snapshot-retention" ], "gid": 0, "mode": 16877, "mon_addrs": [ "145.238.187.184:6789", "145.238.187.185:6789", "145.238.187.186:6789", "145.238.187.188:6789", "145.238.187.187:6789" ], "mtime": "2024-02-02 14:12:30", "path": "/volumes/_nogroup/erasure/998e3bdf-f92b-4508-99ed-69f03a7303e9", "pool_namespace": "", "state": "complete", "type": "subvolume", "uid": 0 } >From the mon server I was able to mount the «partition» with mount -t ceph admin@fXXXXXXX-c0f2-11ee-9307-f7e3b9f03075.cephfs=/volumes/_nogroup/erasure/998e3bdf-f92b-4508-99ed-69f03a7303e9 /mnt but on my test client I'm unable to mount root@ceph-vo-m:/etc/ceph# mount -t ceph vo@fxxxxxxx-c0f2-11ee-9307-f7e3b9f03075.cephfs=/volumes/_nogroup/erasure/998e3bdf-f92b-4508-99ed-69f03a7303e9/ /vo --verbose parsing options: rw source mount path was not specified unable to parse mount source: -22 root@ceph-vo-m:/etc/ceph# So I copy the /etc/ceph/ceph.conf on my client Put the /etc/ceph/ceph.client.vo.keyring on my client No firewall between the client/cluster. Weird part is when I run a tcpdump on my client I didn't see any tcp activity. Anyway to debug this pb ?
