nfs exports and netmask option
Setting up nfs on a redhat ES 4 gives me following issue that i
can't explain.

My nfs was working perfect whith following /etc/exports on the server

Code:
/home/test/nfstest    198.9.200.227(rw,sync,no_root_squash)

But after a powerloss and restart of the server it only works with the following.

Code:
/home/test/nfstest	    198.9.200.227/24(rw,sync,no_root_squash)

I also had to remove the mount on the client it was giving rubbish.
The client was not down.

if i don't add the /24 netmask option i get following error

Code:
exportfs: No host name given with
/home/test/nfstest(rw,no_root_squash)
(ro,async,wdelay,hide,secure,root_squash,no_all_squash,subtree_check,secure_locks,mapping=identity,anonuid=-2,anongid=-2),
suggest
*(ro,async,wdelay,hide,secure,root_squash,no_all_squash,subtree_check,secure_locks,mapping=identity,anonuid=-2,anongid=-2)
to avoid warning

So my question is. Why do i suddenly need to add the netmask option. I am sure it was not there before before the powerloss

mount.nfs

MOUNT.NFS(8)						      System Manager's Manual						      MOUNT.NFS(8)

NAME

       mount.nfs, mount.nfs4 - mount a Network File System

SYNOPSIS

       mount.nfs remotetarget dir [-rvVwfnsh ] [-o options]

DESCRIPTION

       mount.nfs is a part of nfs(5) utilities package, which provides NFS client functionality.

       mount.nfs  is  meant to be used by the mount(8) command for mounting NFS shares. This subcommand, however, can also be used as a standalone
       command with limited functionality.

       remotetarget is a server share usually in the form of servername:/path/to/share.  dir is the directory on which the file system	is  to	be
       mounted.

       Under  Linux  2.6.32  and  later  kernel  versions, mount.nfs can mount all NFS file system versions.  Under earlier Linux kernel versions,
       mount.nfs4 must be used for mounting NFSv4 file systems while mount.nfs must be used for NFSv3 and v2.

OPTIONS

       -r     Mount file system readonly.

       -v     Be verbose.

       -V     Print version.

       -w     Mount file system read-write.

       -f     Fake mount. Don't actually call the mount system call.

       -n     Do not update /etc/mtab.	By default, an entry is created in /etc/mtab for every mounted file system. Use this option to skip making
	      an entry.

       -s     Tolerate sloppy mount options rather than fail.

       -h     Print help message.

       nfsoptions
	      Refer to nfs(5) or mount(8) manual pages.

NOTE

       For further information please refer nfs(5) and mount(8) manual pages.

FILES

       /etc/fstab	 file system table

       /etc/mtab	 table of mounted file systems
