Hello Dario Thanks for your reply. No luck using those too..
Also, I want to mount cephfs to proxmox, there also getting issue mounting.. # mount -t ceph admin@.van2-dev=/ /cephfs/ -o noatime,ms_mode=prefer-crc,_netdev mount error: no mds (Metadata Server) is up. The cluster might be laggy, or you may not be authorized I am using ceph version 19.2.2 and client is also 19.2.2.
