Update /etc/services with new mountd entries.Ĭheck/set nfs_use_reserved ports parameter:ġ. If a client cannot access the network or server, the user must start the machine again in maintenance mode and edit the appropriate mount requests.ģ. Mounts that are non-interruptible and running in the foreground can hang the client if the network or server is down when the client system starts up. On hard mounts, the intr option should be used to allow a user to interrupt a system call that is waiting on a crashed server.ĭefine bg in the /etc/filesystems file when establishing a predefined mount that will be mounted during system startup.

After the set number of retransmissions has been used, the soft mount gives up and returns an error.Ī hard mount retries a request until a server responds. This re-transmit value is defined by the retrans option. Therefore, read-write remote filesystems should always be mounted hard, and the intr option should be specifed to allow users to make their own decisions about hung processes.Ī soft mount will try to re-transmit a number of times. However, for a read-write filesystem, a pending request could be a write request, and so simply giving up could result in corrupted files on the remote filesystem. This is fine for filesystems mounted read-only. It would seem that mounting filesystems soft would get around the hanging problem. (this will not put fs in the /etc/filesystems) (this will do all necessary actions automatically) There are 3 alternatives: smitty, mounting manually, mknfsmnt Mknfsexp -d dir it exports the given directory (it inserts a line in /etc/exports) export the directories which are in the /etc/exports (/etc/xtab: used by the system, and it shows what is currently exported)Įxportfs -a exports all items listed in /etc/exports, and copies these entries to /etc/xtabĮxportfs /dirname exports named directoryĮxportfs -i /dirname temporarily exports (-i: it specifies that the /etc/exports file is not to be checked)Įxportfs shows what is currently in /etc/xtabĮxportfs -u /dir unexports the directories you specify ora_backup -sec=sys:none,rw,root=aixacadb1:aixacadb2Ģ.

If the file exists than the system will be a server and the appropriate daemons will be started.ġ. When nfs (/etc/rc.nfs) is started it checks the existence of /etc/exports file.
