Managing NFS Exports
Network File System (NFS) exports provide an eective way of sharing les across a UNIX or Linux network with authorized clients.
After creating NFS exports, NFS clients then need to mount each NFS export. The
FluidFS cluster fully supports NFS protocol
version 3 and all requirements of NFS protocol versions 4.0 and 4.1.
• Supported NFSv4 features:
– File and byte-range locking
– Kerberos v5 security using an AD server
– AUTH_SYS legacy weak authentication
– UID translation using an LDAP server (UNIX or AD) or a NIS server
– UTF-8 le and directory names
• Unsupported NFSv4 features:
– Delegation of le locks to clients
– Full interoperability between NFSv3 and NFSv4 (for example, conict resolution for locks from clients using dierent
protocols)
– Antivirus scanning and result caching
– LIPKEY and SPKM-3 security (not mandatory in NFSv4.1)
– Kerberos UNIX server
