What is the default value of the NFS timeo parameter ?

[CITEC HP TEAM]

When mounting an NFS filesystem, one of the options is called timeo, the NFS timeout value in tenths of a second. The man page for mount_nfs mentions that the default value for this parameter is set by the kernel.

How can I determine this default value ?

Hi:

When you mount an NFS filesystem you can specify the option as you stated.

From document #KBRC00002736 it appears that the default value for timeo=7.

You should be able to see the timeo value in /etc/mnttab.

A good document which discusses NFS performance is #KBAN00000261.

Hopefully this helps.

the timeo default value is 7 (I found in Installing and adminstering NFS services).
the maximum value is 30 ( 3 seconds).

Hope this helps.
