I had written a shell script to query the NetApp filers for user and qtree quota about 4+ years ago. Its been in production at work since then and has found immense use. I finally efforted a modified and generalized version of that utilitiy and ported it to perl, now that I have the net-snmp perl module installed.
Download the perl script here
Read the mage page here
The script will allow your users to obtain user and qtree quota related information without gaining access to the filer console. It uses the SNMP MIB from NetApp and the perl Net::SNMP module.
Usage:
rajeev@box% ./getquota.pl -help
Options:
-help Print usage info and exit.
-man Print the manual page and exist.
-home Query and print the user quota information. If no username is
passed, then the quota information for the running user is
provided. Optionally, a username and the hosting filer name can
be passed to query the usage information of that user. See
EXAMPLES below.
-filer Filer name where the resource is exported from
-volume Volume name. Requires -f.
-qtree Qtree name. Requires -f and -v.
Obtaining user quota information
Most places I know use the NetApp user quotas for the home directories and mount them at /home/username. As a normal user, you can get the home directory usage information with this script as follows:
rajeev@box% ./getquota.pl -home Home Area quota for: rajeev Current Usage: 1.3 GB Current Limit: 2 GB
To obtain quota information for a specific qtree in a given volume:
rajeev@box% ./getquota.pl -f toaster -v projects -q ABC Quota for: /vol/projects/ABC Current Usage: 1 GB Current Limit: 1.6 GB # of Files Used: 64105
In addition to reporting the space consumption, the script will also spit out the # of files being used.
To obtain a volume specific information:
rajeev@box% ./getquota.pl -f toaster -v projecta Quota for: /vol/projecta/ Current Usage: 725.9 GB Current Limit: 794.6 GB # of Files Used: 24791968
From the above info, I can also infer that my average file size is around 30KB – and also there are lots of them. This might help in designing your backup environments, snapmirror etc. as well.

It appears that your system’s perl installation does not have net-snmp module installed. You need that for this perl script to work (since it makes SNMP calls)
When running the script I’m getting an error…
Can’t locate Net/SNMP.pm in @INC (@INC contains: /usr/opt/perl5/lib/5.8.0/aix-thread-multi /usr/opt/perl5/lib/5.8.0 /usr/opt/perl5/lib/site_perl/5.8.0/aix-thread-multi /usr/opt/perl5/lib/site_perl/5.8.0 /usr/opt/perl5/lib/site_perl .) at ./getquota.pl line 21.
BEGIN failed–compilation aborted at ./getquota.pl line 21.
Nice script.
I’ve got a feature request: could you add an integer percentage output of quota so it can be incorporated into Nagios?(Unfortunatly I can’t program in Perl myself). Would be great!
I’m not sure if the next is possible: another nice feature would be to know whichs qtree’s are over an certain percentage of quota (e.g. 90%), without having to specify the qtree’s.
Keep up the good work.
Good and useful tool. Thanks
