When a NFS filesystem mount is a Hard mount, an NFS request affecting any part of the mounted resource is issued repeatedly until the request is satisfied for example, the server crashes and comes back up later. Once the server is back online, the program will continue to execute undisturbed from the state where it was during server crash.

Hence the recommended settings are hard and intr options. If no version is specified, NFS uses the highest version supported by the kernel and the mount utility. The option vers is identical to nfsvers , and is included in this release for compatibility reasons.

These options set the maximum number of bytes to be transferred in a single NFS read or write operation. There is no fixed default value for rsize and wsize. By default, NFS uses the largest possible value that both the server and the client support. In Red Hat Enterprise Linux 8, the client and server maximum is 1,, bytes.

For more details, see the What are the default and maximum values for rsize and wsize with NFS mounts? KBase article. Security flavors to use for accessing files on the mounted export. The flavors value is a colon-separated list of one or more security flavors. By default, the client attempts to find a security flavor that both the client and the server support.

If the server does not support any of the selected flavors, the mount operation fails. Chapter 3. Mounting NFS shares. NFS version 3 NFSv3 supports safe asynchronous writes and is more robust at error handling than the previous NFSv2; it also supports bit file sizes and offsets, allowing clients to access more than 2 GB of file data.

Sparse files Enables files to have one or more holes , which are unallocated or uninitialized data blocks consisting only of zeroes.

The lseek operation in NFSv4. Space reservation Permits storage servers to reserve free space, which prohibits servers to run out of space. Enhances performance and security of network, and also includes client-side support for pNFS. No longer requires a separate TCP connection for callbacks, which allows an NFS server to grant delegations even when it cannot contact the client: for example, when NAT or a firewall interferes.

Provides exactly once semantics except for reboot operations , preventing a previous issue whereby certain operations sometimes returned an inaccurate result if a reply was lost and the operation was sent twice. These ports are then made available or advertised so the corresponding remote RPC services can access them.
