Nfs not updating client
Should the request not succeed after n retransmissions, a soft mount returns an error, and a hard mount retries the request.
The default retrans value is 4 This refers to the maximum number of seconds a directory’s attributes are cached on the NFS client. if the timeout period expires, the client flushes its attribute cache, and if the attributes have changed, the client sends them to the NFS server.
For a file that rarely changes or that is owned and modified by only one user, like a file in a user’s home directory, decrease the load on your network by setting the acregmax=120 or higher.
The Network File System is certainly one of the most widely used network services.
For a directory that seldom changes or that is owned and modified by only one user, like a user’s home directory, decrease the load on your network by setting this attribute to acdirmin=60 This refers to the maximum number of seconds a file’s attributes are cached on the NFS client.
Should the timeout period expire, the client flushes its attribute cache, and if the attributes have been altered, the client sends them to the NFS server.
The number of times the NFS client attempts to mount a directory after the first attempt fails.
By default, this value is 1 This refers to the number of times that an NFS request (a read or write request to a mounted directory) is retransmitted after it times out.
At this point, we assume that the NFS service daemon is already installed on your system, including portmap daemon on which NFS setup depends.If you have not done so yet simply install nfs-common package on both NFS client and NFS server using using apt-get tool.This package is the actual NFS daemon listenning on both UDP and TCP 2049 ports.This is the most secure setting, but it also has the most performance overhead involved. This is achieved by setting a larger data block size, in bytes, to be transferred at one time.Caution should be taken when changing these values; some older Linux kernels and network cards are not compatible with larger block sizes.
Search for nfs not updating client:
When installed correctly, the NFS daemon should be now listening on both UDP and TCP 2049 port and portmap should be waiting for instructions on a port 111.
