Mount options for nfs
Instead of a textual option string, parsed by the kernel, the nfs filesystem expects a binary argument of type struct nfs_mount_data. The program mount itself parses the following options of the form 'tag=value',and puts them in the structure mentioned: rsize=n, wsize=n, timeo=n, retrans=n,acregmin=n, acregmax=n, acdirmin=n, acdirmax=n, actimeo=n, retry=n,port=n, mountport=n, mounthost=name, mountprog=n, mountvers=n, nfsprog=n,nfsvers=n, namlen=n. The option addr=n is accepted but ignored. Also the following Boolean options, possibly precededby no are recognized: bg, fg, soft, hard, intr, posix, cto, ac, tcp, udp,lock. For details, see nfs(5).
Especially useful options include
- rsize=32768,wsize=32768
- This causes the NFS client to try to negotiate a buffer sizeup to the size specified. A large buffer size does improve performance,but both the serverand client have to support it. In the case where one of these does notsupport the size specified, the size negotiated will be the largestthat both support.
- intr
- This will allow NFS operations (on hard mounts) to be interrupted while waiting for a response from the server.
- nolock
- Do not use locking. Do not start lockd.
Mount options for nfs4
Instead of a textual option string, parsed by the kernel, the nfs4 filesystem expects a binary argument of type struct nfs4_mount_data. The program mount itself parses the following options of the form 'tag=value',and puts them in the structure mentioned: rsize=n, wsize=n, timeo=n, retrans=n,acregmin=n, acregmax=n, acdirmin=n, acdirmax=n, actimeo=n, retry=n,port=n, proto=n, clientaddr=n, sec=n. The option addr=n is accepted but ignored. Also thefollowing Boolean options, possibly preceded by no are recognized: bg, fg, soft, hard, intr, cto, ac,For details, see nfs(5).
