Thread: How to verify the options used when mounting a nfs FS.

After mounting an exported NFS file system:
# mount -F nfs nfs_server:/mnt /mnt_point

How do I verify what's the default options being used?
In Linux, we can issue the command "mount" or "cat /proc/mounts" then we can see what are the defaults options being used. The size of r/wsize, what's the protocol used, etc..right?
So in Solaris, how can I verify it?

thanks,

Use mount -v command:

Code:

mount -v

Output:
/dev/dsk/c0d0s0 on / type ufs read/write/setuid/devices/intr/largefiles/logging/xattr/onerror=panic/dev=1980000 on Mon Mar 27 12:54:59 2006
/devices on /devices type devfs read/write/setuid/devices/dev=3340000 on Mon Mar 27 12:54:53 2006
/dev/dsk/c0d0p0:boot on /boot type pcfs read/write/setuid/devices/nohidden/nofoldcase/dev=19a3010 on Mon Mar 27 12:54:57 2006
proc on /proc type proc read/write/setuid/devices/dev=3380000 on Mon Mar 27 12:54:58 2006
mnttab on /etc/mnttab type mntfs read/write/setuid/devices/dev=3440001 on Mon Mar 27 12:54:59 2006
fd on /dev/fd type fd read/write/setuid/devices/dev=3480001 on Mon Mar 27 12:54:59 2006
swap on /var/run type tmpfs read/write/setuid/devices/xattr/dev=3500001 on Mon Mar 27 12:54:59 2006
swap on /tmp type tmpfs read/write/setuid/devices/xattr/dev=3500002 on Mon Mar 27 12:54:59 2006

Red colour displays the options. Another way is to see /etc/mnttab file:

Code:

cat /etc/mnttab

Output:

/dev/dsk/c0d0s0 / ufs rw,intr,largefiles,logging,xattr,onerror=panic,dev =1980000 1143444299
/devices /devices devfs dev=3340000 1143444293

mnttab /etc/mnttab mntfs dev=3440001 1143444299

Thanks so much for the information.
ok, seems this is the only supported options when mounting a nfs in Solaris...
read/write/setuid/devices/nohidden/nofoldcase/dev=19a3010

Also in the manual I cannot find how to mount it using tcp or udp, hard or soft. Anyone knows what are the default for the ff:
tcp or udp?
hard or soft?
rsize/wsize size?
nfs version?
intr or nointr?
timeo=?
etc....

Some of these options will definitely depends on the client.

thanks,
warren

Use syntax:

Code:

mount -F nfs -o OPTIONS HOST:PATH /path/to/local

Where,

OPTIONS can be tcp or udp, hard or soft etc. To see all option read man page mount_nfs.

Code:

man mount_nfs

ok, I see it all...
man mount_nfs

problem solved...thanks to monk and rockdalinux

warren

$ sudo apt-get install nfs-common
$ sudo mount 10.126.12.36:/data /mnt

it works
