10 TB nfs mount

sreeram n — Thu, 04 Mar 2010 14:03:57 GMT

Hi,

We got a requirement to mount a NFS filesystem of 10 TB on hpux 11.23 system
This filesystem will be exported from an EMC datamover.

If we mount such huge filesystem using NFS, will there be network traffic even if we are not reading/writing to that file system.

We are using a 1GBPS network.

Thanks
Sree

hi,

i think if you don't use the exported file system there should by an minimal traffic.

Why would there be? Are you expecting long
conversations between nfsd and mountd like:

"Are you really that big?"
"Yes, I am!"
"Really?"
"Yes."
"Really?"
"Yes."
[...]
?

Steven,

That one was nice. Thanks for explaining in such simple words.

What all are the things we need to take care while mounting a huge nfs.
If you can point me to any doc that will be great.

Thanks
Sreeram

I'm confused... why would there be network traffic, which I assume you mean NFS traffic, if the filesystem is not being used?

Whethe rthe filesystem is 100 MB, 100 TB or even 100 PB, NFS is still NFS. If you don't talk to the filesystem (ie, directory queries, open/close or write/read files) then there is no LAN traffic. Of course if this filesystem has one giant directory with 100 million files, looking at the directory will be very intense...
