User based Quotas - Why don't they show up correctly when mapped?

More fun with user based quotas. When a user has a mapped CIFS share to
their home drive the size of the entire volume shows up when they map
the drive. I thought user quotas used to just show the "quotaed" space
for that user.

I.E. I have a 11TB volume. I create a user quota of 500MB and apply it
to a user (say xyz99). When XYZ99's home share is mapped they see 11TB
available to them, not 500MB. A tree based quota with a hard limit
works just fine in showing only 500MB available.

I've worked with Netapp support and did get an obscure bug (88541
<http://now.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=88541> ) that
has no information and a reply that there isn't much information on this
issue. (Maybe the functionality just isn't there? I could swear we used
to have that function.)

Does anyone use user quotas and have this same problem?

Are there better ways to do user home share type CIFS shares?

Thanks

Re: User based Quotas - Why don't they show up correctly when mapped? [In reply to]

We are using user quotas for our users and it shows the capacity based on
their quota, not the entire volume. We are using 7.2.6.1. Perhaps your
quotas aren't enabled or haven't completed a resize operation?

RE: User based Quotas - Why don't they show up correctly when mapped? [In reply to]

I'm running 7.2.5.1p6 (upgrading to 7.2.6.1 this weekend)

They are enabled, and active (can't put more data than the quota is set
to). I've even created a monitoring tree based quota per the
documentation from netapp.

Here's a modified version of my quotas for homeshares

#USER HOME SHARES BEGIN

* user@/vol/VOLUME/QTREE04 - - -
1048576K -

* user@/vol/ VOLUME/QTREE09 - - -
104857600K -

* user@/vol/ VOLUME/QTREE02 - - -
102400K -

* user@/vol/ VOLUME/QTREE06 - - -
10485760K -

* user@/vol/ VOLUME/QTREE10 - - -
209715200K -

* user@/vol/ VOLUME/QTREE01 - - -
20480K -

* user@/vol/ VOLUME/QTREE07 - - -
26214400K -

* user@/vol/ VOLUME/QTREE03 - - -
512000K -

* user@/vol/ VOLUME/QTREE08 - - -
52428800K -

* user@/vol/ VOLUME/QTREE05 - - -
5242880K -

* user@/vol/ VOLUME/QTREE11 - - -
20480K -

#USER HOME SHARES END

Here's a direct quote from Netapp Support re: my issue of USER quotas
not properly showing when mapped

"I wanted to find you some documentation for this condition but found
little. However, I did confirm your suspicion that this is by design"

To me that says what you have currently should not work. Sigh... round
and round we go J

Thanks for the info, It will give me more firepower to figure out what
the issue really is.

Re: User based Quotas - Why don't they show up correctly when mapped? [In reply to]

We also are using user level quotas and it shows up just fine when mapped.
are you using usermap.cfg to definite your qtrees as homedir qtrees, so
the mapping is \\filer\userid?
do all your users infact "own" their own files. if using unix security
style for your qtrees this is usually easy to check.
If using ntfs security style this is more difficult to check and set,
but you have to make sure that the "owner" of the files and the
directories is the individual user. (we use unix security style, it
makes things much easier to script up)
the only exception we have run into is if the user is in the
administrators group, if this is the case you must set
wafl.nt_admin_priv_map_to_root to off for the quota to appear properly
for those users in the local administrators group. if you set that
option to off, then the quotas show up correctly, even for the admins.

RE: User based Quotas - Why don't they show up correctly when mapped? [In reply to]

We use CIFSHOMEDIR to "create" a \\filername\username\ share that is
mapped via a logon script. We use NTname in CIFSHOMEDIR. Is it
possible since these aren't "real" shares there is a disconnect between
the quota and the share?

Unfortunately it would be a pain to have an individual entry for every
user in the usermap.cfg file. We have over 50,000 user homeshares.

Also, the issue isn't just admins it's all users, but that is a nice tip
that I may implement just so everyone is on the same page :).

Re: User based Quotas - Why don't they show up correctly when mapped? [In reply to]

There is a tool in the Toolchest on the NOW site called na_chstuff. Within
it is one called na_chmod.exe I have a script that I run at 3am every day
that uses this to change the ownership of each folder based on the users'
login name. We have our user shares saved as filername:/vol/users/username
and shared as \\filername\users. They are using NTFS security style and no
QTrees. Authenticated Users has List on the first level subfolders with
Administrators, System, and Creator Owner having Full Control of everything.
The script is something like (I'm at home and doing this off the top of my
head):

for /d %f in (\\filername\users\*.*) do na_ntfschown /r domain\%f

The exact syntax may be off a bit, but you get the idea.

Hope this helps.

Yep we use na_ntfschown as well.
I will setup some test shares to test your setup.

RE: User based Quotas - Why don't they show up correctly when mapped? [In reply to]

Don't know if this will help but ...
in a nut shell, Have you tried setting a default user quota on the home qtree then assigning each user a specific quota in addition to the default?

Have no issues with user quotas showing up properly here.
Our structure is like:
/cifsvolume/homeqtree2
/cifsvolume/homeqtree5
/cifsvolume/homeqtree10

Each of the home qtrees has a default user quota applied
- Container one defaults to 250 meg per user
- Container two = 500 meg default
The last container has a default quota of 2 gig.

If someone needs a larger quota we move the home directory to the next container. We then have to run NTFSchown to set the file ownership. If someone exceeds the largest default, I apply a specific user quota only to that person. Manage by exception thing.

Moving home folders and chowning is a bit of a pain but I could not think of a better way to do this without having to apply specific quotas to all 12,000 accounts. We don't get a lot of requests for larger home quotas - about ½ a dozen or less per week.

Our home drive shares are set to the hidden style. When each user connects they map to \\filer\username$<file:///\\filer\username$> to get their H: I made a mistake when setting this up. We can assign a home drive mapping to the user in the Active directory MMC but the MMC will not create the H drive. We have to create the home folder manually. Not a big issue as we are not allowed to create user accounts manually. Our IDM system has a script that runs to create and ACL the home folder when the account is created.

One other thing:
We use windows folder redirection here to ensure that the "my documents" folder is saved to the user's H: drive. Could not make this work until we gave each user full-control on their own H:. This has nothing to do with quotas not showing up properly. Quotas worked fine before this change. Thought I'd mention it though.

More fun with user based quotas. When a user has a mapped CIFS share to their home drive the size of the entire volume shows up when they map the drive. I thought user quotas used to just show the "quotaed" space for that user.

I.E. I have a 11TB volume. I create a user quota of 500MB and apply it to a user (say xyz99). When XYZ99's home share is mapped they see 11TB available to them, not 500MB. A tree based quota with a hard limit works just fine in showing only 500MB available.

I've worked with Netapp support and did get an obscure bug (88541<http://now.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=88541>) that has no information and a reply that there isn't much information on this issue. (Maybe the functionality just isn't there? I could swear we used to have that function.)

Does anyone use user quotas and have this same problem?

Are there better ways to do user home share type CIFS shares?

Thanks

RE: User based Quotas - Why don't they show up correctly when mapped? [In reply to]

That very similar to our architecture, only we don't move the user's home share we use DFM to manage the quota size and upgrade them in place thus avoiding needing to migrate dozens of users every day (We used to migrate users into a new quota bucket but it became too labor intensive as we have over 80,000+ home shares, and 50,000+ users) .

Do you use CIFS homedir to make the username$ share, or do you manually make the shares? Are you shared user folders Qtrees?
