Hi Oliver Review this "step by step" guide to see if you forgot something: BR NFS: 1. chmod +x cephadm 2. ./cephadm bootstrap - Record dashboard user & password printed out at the end 3. ADD OTHER HOSTS (assuming 3+ total after adding) 4. ./cephadm shell 5. ceph orch apply osd --all-available-devices 6. ceph fs volume create test 1 7. ceph orch apply mds test 3 8. ceph nfs cluster create cephfs testnfs 9. ceph nfs cluster info testnfs - (verify hostname, ip and port are listed) - Record ip and port for later 10. ceph nfs export create cephfs test testnfs /cephfs 11. ceph auth ls - (check “client.testnfs1” keyring is present) 12. ceph nfs export get testnfs /cephfs - (should have output) 13. rados -p nfs-ganesha -N testnfs get export-1 - testnfs/cephnfs - (check that export was successfully created) 14. ceph nfs export ls testnfs - (should show pseudo path “/cephfs”) 15. Verify nfs export exists on dashboard - Login to dashboard with credentials from bootstrap - URL will be https://{host-ip}:8443/ - Navigate to NFS page - Table should contain the export you just created 16. Exit shell - Command should just be “exit” 17. systemctl status nfs-server - If service is listed as inactive, run “systemctl start nfs-server” - Run “systemctl status nfs-server”. Should now be active 18. sudo mount -t nfs -o port={nfs-port} {nfs-ip}:/cephfs /mnt - Port and ip should be from “ceph nfs cluster info testnfs” command ran earlier Ex: mount -t nfs -o port=2049 10.8.128.94:/cephfs /mnt/cephfs/ Then give mount command -> to check if its mounted #mount Output: 10.8.128.94:/cephfs on /mnt/cephfs type nfs4 (rw,relatime,seclabel,vers=4.2,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=10.8.128.94,local_lock=none,addr=10.8.128.94) -- Juan Miguel Olmo Martínez Senior Software Engineer Red Hat <https://www.redhat.com/> jolmomar@redhat.com <https://www.redhat.com/>
