UNSOLVED
CIFS quota reporting file sizes/file count incorrectly
I'm having a frustrating problem with Celerra 5.5. I have an open support ticket, but they are equally as stumped. I'm hoping someone here has run into this problem before and has a solution.
I am sharing out a filesystem via CIFS to contain our Windows users home directory (i.e. [cifs_server]/users/(username)). This works fine, but I want to enable user quotas on this file system.
The problem is that Windows and the Celerra disagree as to the number of files and thier sizes. For example, in my personal share, Celerra says I am using 110 GB of storage, while Windows reports that I'm using 1.79GB. A random sample of 10 other users indicates the same problem for other users as well.
I've made sure that my server_param is measuring "filesize", and I've unmount/remounted the file system to force recalculation. So far, nothing has work to bring the two numbers into accordance with each other.
There are no tree quotas, so user quotas are only affecting the single UID/SID (as far as I know).
Also, if I cannot always reliably see the "quota" tab in Windows from these mapped drives - sometimes I have to remove a mapping, then re-map it to get the quota tab to appear. And, when doing this, bringing up the "properties" tab for the mapped drive takes a very, very long time. I had been hoping that our helpdesk folks could manage quotas via Windows in this way, without needing to log into the Celerra or use the Web GUI.
Why are the file counts and file sizes different in Windows vs Celerra and what can I do about it?

Thanks! Do you recall the name of the script or who you spoke to? So far, EMC doesn't know what I'm referring to by "the lab".626

Was the script a one time thing, or did you need to run in regularly to fix the problem?626

I'm in the lab, and I don't know of this script.
Do you have the SR number from this incident that I can reference? Feel free to e-mail it directly to me if you don't want to post it.
v/r, bill626

Hi Bill,
Thanks for looking into this. I appreciate it. I also have this open on SR#22425874. I'm really hopefull that this script will solve my problem. I based my entire migration to the SAN around the idea of implementing user quotas, so to discover that they aren't working correctly was a big disappointment. I've had this case open for awhile and so far nobody has been able to figure out why this is happening. I'm really counting on this mystery script to save the day.626

stegad -
Are the values being reported from Windows the actual values (used/available) for the entire file system on which your user home directories reside?626

Sort of, if I follow you. Windows Explorer shows the size of the entire file system for each mapped drive, yes. So, for exampe, the mapped drive to my share reports a total size that equals the entire storage pool for that filesystem, instead of my quota. That's only a minor inconvenience.
The problem is that if I select "properties" of that mapped drive (and IF the quota tab decides to show up), the sizes reported for each share do not match what is actually there. Or if I lookup quota info from either the celerra CLI or web GUI.
The strange thing is that discrepancy is not consistent. My share shows the largest variance (110GB used in celerra vs. 1.7gb of data actually there), but other shares are off by a different, but significant, amount (i.e. Celerra reports 850 mb used when actually there's only 240 mb of "stuff").204

Is the cifs.useQuotaInFsStat server parameter set? What's the output of "server_param server_2 -facililty quota -info useQuotaInFsStat"?
