Hi Mariog  userquota is calculated with the filespace the files of a specific user use.  Since YOU copied the data, YOU are the owner of these files and they will NOT take part in the calculated "used space" of another user but you.  This is why I would recommend you to use directoryquotas. They are much easier to understand for the user and you do not consume any space in this directory which you don’t see in the quotation. Also cases in which your administrators restore files or copy files to the specific homedrive do not pass by the quotation. Since in a normal environment only one user and the administrators have access to the homedirectory the directoryquota does exactly what you need it to do.  For me (in my workload and my environment) the userquota would only be useful on groupdrives to audit specific users.  If you have to (for any reasons) use the userquota, after migration use setacl.exe or any other tool to set the owner of all files in the homedirectory to the user who owns the homedirectory.  Docu50238 (Isilon Guidelines for Large Workloads) do not show any quota-limitation, but a share limit of 10K (which is also not recommended). So please use a central share and map the subfolders as (cluster\Homes$\user1 cluster\Homes$\user2 cluster\Homes$\user2>)  In my environment we have more than 10K directoryquotas on a three node cluster and do not face any problems. This does NOT mean you won’t get any [IMAGE]  Regards sluetze
I am planning a migration from a windows file server to my Isilon and am trying to figure out the best way to manage my users home shares.  We have 2500 shares ranging from 10 MB to 50 GB with a majority of the users under 10 GB.  My organization is going to double in size and I wanted to see if others have run into any problems managing home shares using directory quotas.  I understand this route will require more manual work that can be accomplished through scripting, but will also give us more control.   Do others prefer to use the user directory quota?  I noticed that when I copy over the directories to a test user quota directory, it will not pick up the data that I copied over.   Example:  I create a 300 MB quota and copy over 200 MB before attaching the user.  When I assign the home directory to the user, it shows that 0 MB of that quota is being used.  Any feedback would be appreciated.  Thank you   
Isilon quotas - directory or user?
