How to know whether a given directory in in NFS

How to know whether a given directory in in NFS

[Raghu Ram Murthy]

Hi,

I want to know (from perl), whether a given directory
is in part of NFS. Are there any Unix commands to find
it out or any indirect methods?

Thanks in advance
-Raghuram

How with mount.

for example, /home directory is in NFS and /tmp is not
in NFS and I don't know whether /home is in NFS or
not?

Then how can I find?

You can use the statfs system call (on Linux) - see a similar thread at 
http://marc.theaimsgroup.com/?t=108784378500006&r=1&w=2

There is probably a statfs Perl module.

mount will return a line within:

nfs_server:/an/exported/directory/ on /home type nfs
or
nfs_server:/an/exported/directory/ on /home type nfs4

depending on the nfs version you are using.

You can parse the mount result. I don't know if there is an other way to kn=
ow=20
that?

IMO, python's a lot more practical than perl (at least until perl is
majorly overhauled for perl 6 :-S).

With python, the "os" module has a statvfs function, and the statvfs
module has symbolic constants to facilitate using the os.statvfs
function.

I used this API recently to summarize disk usage in a filesystem that
doesn't have quota support.  I had to compile python with "large file"
support though, even though IBM claims in some contexts that programs
are supposed to be large file-enabled on AIX by default.  But of course,
this assumes you'll be looking at somes that are over 2 gigabytes in
size...

"df <directory-name>" or the equivalent call the df command
uses (vfstat I think or something similar) works nicely.
