We've just turned on user quotas and I am trying to figure out a way to allow users to check their current disk usage and quota limit. Since the filer is running rquotad, this would seem to be the way to go. But alas, the filer rquotad apparently wants quota [path] instead of quota [uid], just like its command line quota report.

Really? That's not what the quota daemon code in ONTAP appears to do - prior to 5.0, it *ignored* the pathname sent over the wire (you only had one file system) and used only the UID, and, in 5.0, it gets the (internal) file system ID of the file system on which the pathname resides, and looks up the quota for the UID in question.

I've attached a source to a program that should build under SunOS 4.x, (sufficiently recent) SunOS 5.x, and Digital UNIX 4.x (and maybe earlier) if you have a compiler that handles function prototypes (it built with GCC on SunOS 4.1.4 and 5.5.1 and Digital UNIX 4.0C) - and, if you remove the stuff to get quotas from local file systems, or rewrite it for your particular OS, should compile under them as well, if you also have "rpcgen" and an ONC RPC library.

Tweak the stuff at the beginning of the Makefile to get it to build.

The first argument is:

for a local file system, the pathname of the mount point;

for a file system on an NFS server, the host name of the NFS server, a colon, and the directory on the server.

The second argument is the user name or UID of the user whose quota is to be checked.

Try running that against the filer (using the "<hostname>:<directory>" syntax), and see what it returns. (I've not tested its ability to get quotas for local file systems, as we don't have any local file systems handy with quotas on them....)

Has anyone figured out a way to allow a general user to check their disk usage and quota limits?

On some flavors of UNIX, the "quota" command should do it. "quota", with no arguments, should report, for all local file systems with quotas, and all NFS file systems not mounted with "noquota" (and mounted from a server with a quota daemon), quota information for the user in question.

On others (I think some lack a "quota" command), you can probably cannibalize the attached program and turn it into a "quota" command, which may involve

making it loop through all file systems on which you can get quotas (NFS and maybe local);

adapting the local file system quota code to your particular flavor of UNIX.

(Then ship it back to the supplier of that flavor of UNIX and tell them to call it "quota"....)

From: Mike Mueller Mike.Mueller@jpl.nasa.gov Date: Fri, 22 May 1998 16:00:59 -0700 Subject: User Quota Checking To: toasters@mathworks.com

We've just turned on user quotas and I am trying to figure out a way to allow users to check their current disk usage and quota limit. Since the filer is running rquotad, this would seem to be the way to go. But alas, the filer rquotad apparently wants quota [path] instead of quota [uid], just like its command line quota report. It returns "NO QUOTA" when queried via a client's quota command.

Has anyone figured out a way to allow a general user to check their disk usage and quota limits? It looks like there may be a way through the MIB, but how could this be easily made into a command line script that a user could run? Better yet, is there a way to allow the user to interact with the rquotad deamon that is already running on the filer to get their quota report? If not, why is it running?

Thanks for your insight! -- Mike
