File Systems,Tree Quotas, CIFS and Windows users
I have several departments which each need around 1 TB of disk space on my new Celerra ns-120. All clients are windows 7 or windows xp.
I was going to create two file systems and then use tree quotas to limit the directory size for each department. So I would have 2-3 departments on each file system which would be about 2.5 TB for each file system.
However, it seems that the users see the entire space free for the entire file system, not just for their specific folder (or tree quota structure). Is there away for windows users to know how much quota space they have left? I saw something about a quota tab but I don't see anything in Windows 7.
If I can't show the quota space available, should I create a file system for each department (there are 6) so that they can see actual space free on their cifs shares? I will also be replicating these file systems to a secondary DR site and I will also have a file system for VMware via NFS.
Thanks for any help or suggestions.

The Tree Quotas feature requires that the "Deny Disk Space to users exceeding quotas: " be set to yes to report tree quota stats correctly from CIFS clients.
Run the nas_quotas -c -e -fs to set the "Deny Disk Space to users exceeding quotas:" field to yes. (Primus emc82691)

yeah, tree quotas will not hide the actual size of the file system. I am doing something very similar to you. I have a lot of bigger customers that get their own file system (> 500GB), but i also have a lot of smaller customers that it just did not make sense to create a unique file system for each one. So i have one file system where i create different tree quotas for each customer. I wrote a report in perl that customers get on monthly bases so they can see their quota utilization. If you only have 6 departments, i don't see a problem of creating one 1TB file system for each one. It's also much easier to backup and restore smaller file system size, you can throw more tape drives at them.

That works! I didn't even have to re-map drive. After running command, the mapped drive to the folder with the file system quota now only reports that amount of disk space free within the quota, not the entire file system.
Thanks.

Hi all,
I have exactly same situation...and even my "Deny Disk space to users exceeding Quota" is already selected to Yes for that FS.
I have checked that with form the GUI and also from the nas_quotas -c -e -fs .
Actually i have already setup few other quota's tree , on that same FS but when I wanna setup this new quota tree and when the Server guy maps.
the network drive ....with that share path ... and then see properites of that share ... its shwoing as 400GB and not 100GB as per my Hard limit tree quota.
Any help would be good.

Hi,
welcome to the forum
Just make sure you map the path for the treequota and *NOT* the folder above or the file system root or going through C$ and then it will work.
For CIFS there is actually no way to configure the Celerra to not show the treequota size (instead of the file system size) like there is for NFS.
If that still doesnt work you might have to upgrade to a newer DART release - there was one bug fixed recently:
Symptom Desc.
The CIFS full_fs_info request intermittently returned inconsistent results. Instead of returning the
quota limited space available, it returned the volume size. This issue occurred when multiple
full_fs_info requests were sent to Data Mover simultaneously.
Fix
The internal locking mechanism was corrected to properly acquire the lock in order to read the quota
database, and therefore report the correct available size.
Service Request No. 32193068
Fixed in version 5.6.49.0

Hi Rainer,
Thanks for the reply. We are mapping exact path as the path on which quota is applied.
eg: if on FS : fs_NAS_001 (400GB) We have a Tree quota 100GB on path : \fs_NAS_001\live\apps\Testing.
In the above path : Folders live and apps already existed and I created a new TreeQuota with \Testing added which effectively creates the Testing folder and applies tree quota.
Now when I map network drive to : \servername\live\apps\Testing and then see the properties of that Drive it shows me 400GB ( Actually it should show me Quota size of 100GB ) .
I am sharing this via CIFS and client is a Windows client.
Also, Please can you explain me a bit more about the bug fix in the new version. My DART version is : 5.6.42-5.
Regards,
kavan
