NFS in Solaris

Configuration Files (along with a sampel content):

       share -F nfs -o rw /data
       share -F nfs -o ro=-client1:.max.com /export/share/man

/etc/default/fs        -  Lists the default file system type for local file systems
/etc/dfs/fstypes      -  Lists the default file system types for remote file systems
/etc/default/nfs       -  Lists the lockd and nfsd configuration details

/etc/default/nfslogd - Lists the nfslogd configuration details
/etc/mnttab            -  Lists the file systems currently mounted
/etc/rmtab              - Lists the filesystems (shares) currently mounted by the clients

Daemons :

automountd - Used by Autofs
lockd          - Used for file locking purposes
mountd       - Handles mount requests from the clients
nfsd            - Main NFS server daemon which handled the client requets
nfslogd       - Handles operational logging


1. To share all the filesystems as defined in /etc/dfs/dfstab file
# shareall

2. To view the currently shared filesystems :
# share

3. To start the NFS server services :
# svcadm enable network/nfs/server

4. To mount a share as read only in a nfs client :

# mount -F nfs -o ro server10:/oracle /data/oracle

5. To start auto fs :
# svcadm enable system/filesystem/autofs

6. To check if NFS server service is running on the server :
# svcs network/nfs/server

7. To check nfs services on a server from a client machine :
# rpcinfo -s nfsserver| egrep 'nfs|mountd'

8. To list the file systems shared by a server from a client machine :
# showmount -e servername
# dfshares servername

9. To list the shares currently mounted by the clients :
# dfmounts
