NFS related daemons from etcrc. After portmap is running other daemons can be registered to portmap, so it knows correct port of each daemon. When nfs etcrc. If the file exists than the system will be a server and the appropriate daemons will be started. Subsystem         Group            PID          Statusbiod             nfs              1.

TCP on nfs serverAfter the files, directories andor filesystems have been exported, an NFS client must explicitly mount them before it can use them. It is handled by the mountd daemon. It answers RPC requests, it checks etcxtab file to find out what are exported. It shows the currently mounted filesystems, with the help of the command showmount. Port can be specified in etcservices. TCP on nfs serverServices client requests for filesystem operations. Once a clients mount request has been validated by mountd, it is allowed to request various filesystem operations. These requests are handled on the server side by nfsd. If the etcexports file does not exist, the nfsd and the rpc. You can get around this by creating an emptyetcexports file. The lockd daemon on the client sends lock requests to the server lock daemon through the RPC. The lockd daemon then asks the statd status monitor daemon for monitor service. How To Install Gpfs Aix' title='How To Install Gpfs Aix' />The statd daemon interacts with the lockd daemon to provide crash and recovery functions for the locking services. The status monitor maintains information about the location of connections and the status in the varstatmonsm, varstatmonsm. When statd restarted it queries these files and tries to reestablish the connection it had prior to termination. To restart the statd daemon, and subsequently the lockd daemon, without prior knowledge of existing locks or status, delete these files before restarting the statd daemon.

AJlPYqrms8/0.jpg' alt='How To Install Gpfs Aix' title='How To Install Gpfs Aix' />The statd daemon should always be started before the lockd daemon. Not needed anymore, it no longer plays an active role in management of the NFS client subsystem, because an NFS client internally manages its IO operations to NFS servers. The biod daemon is retained for compatibility reasons, becuase earlier versions might have scripts that invoke biod. The biod daemon might be removed in future AIX  releases. Numberof. Biod, which specifies the number of biod threads on the client. This option has no effect and should not be used. If needed number of biod threads should be set as a mount option mount o biods1. For historical reasons only, this is what biod was used for in the past below info is not valid anymore In order to improve overall NFS performance, most systems include the biod daemon which does basic read ahead and write behind filesystem block caching. For example, when an NFS client requests three bytes from a file, a much larger chunk usually 4. K is actually read. When the client reads the next three bytes, no network transaction needs to occur.

It is strongly recommended to run this daemon on all NFS clients, but it is not strictly required. In NFS V4 only nfsd, portmap, biod and nfsgryd name translation service, and supports only TCP in NFS V3 TCP and UDP as well etcexports. The etcexports file contains an entry for each directory that can be exported to NFS clients. This file is read automatically by the exportfs command. If you change this file, you must run the exportfs command to activate these changes. If this file is present during system startup only then does the rc. You cannot export either a parent directory or a subdirectory of an exported directory within the same file system. Syntax for exported directories directory option. Options accessclient. If not specified, any client is allowed to mountro                             lt exports dir with read only permission. If ro is not specified, it is exported with read write permission.
