Hi Bruce,
Sorry it was the mail composer - I did not check mark the plain text option.

We need an opinion.
We will be using around 15 NFS client mounted - with one NFS Server. We are try to make out how many NFSD should we start at the NFS Server.
It all depends upon the load - these 15 NFS clients are going to generate. But is there any default number - we should use to start with? like 1 per NFS client mount?
Please share your advise on this.

Thanks & Regards,
Amit Sahrawat

Could you turn off html formatting on your mail?

The option you mentioned is working. 'exportfs -f'

Actually it is not mentioned anywhere - even when checked for options:

exportfs: invalid option -- 'h'
usage: exportfs [-aruv] [host:/path]



Sorry, it looks like the help test could be improved!  Patches
welcomed....

It is documented in the exportfs man page.

But - when tried to give - '-f' option it is working.

Then on checking the code for exportfs - got to know the working of '-f' option.

I think it should work. I will check with a number of scenario  - to check there is no blockage for other mount points - at the time 'exportfs -f' is being run. Please reply if it wont :)


If no clients are using the export, it should work.
