one quota per volume not default quota and not per qtree?

Hi,

I didn't find an answer to my question - so the details:

  • we have several systems running Ontap 8.1.x
  • some volumes that are matched to departments
  • In these volumes we have several qtrees for cifs projectshares

Now I want to implement quota on these volumes like qtree quota. But I don't want the default qtree quota I want to have a quota on the volume and the projects share this quota.

I didn't want to implement quota at first but the users go on and fill the volumes to 100% and the oncommand monitoring is going crazy. So i'd like to make it quiet by putting a quota on this share.

I already tried

/vol/<volname>/ tree@/vol/<volname>/ 300G  - - - -

but Ontap tells me this is not a valid qtree name.

Any suggestions?

Thanks Patrick

Re: one quota per volume not default quota and not per qtree?

Hi,

you can still use the default quota to achieve this. you need to remove all the other quota entries in the /etc/quotas file except.

* tree@vol/volname/ size_gb - - - -

this means that all qtrees in this volume will have the same quota - i.e. the default quota above.

e.g you have qtree1, qtree2, qtree3 in vol1 and the only the following entry in your /etc/quotas file.

* tree@vol/vol1/ 10g - - - -

then qtree1,qtree2,qtree3 will all have 10g as quota.

Hope this can help.

Re: one quota per volume not default quota and not per qtree?

forgot to mention, you can increase the volume to 15gb for e.g. and have a default quota of 10gb on it so that your volume will never be 100% full but only the qtrees.

Re: one quota per volume not default quota and not per qtree?

Hi,

this doesn't help! I want something like this setup:

One Volume (e.g. 15GB) and several qtrees in this volume.

All volumes together should never use more than 10GB but I don't want to set quota to each qtree. Also one qtree should be able to use 7GB another one 2GB and some more, each less than a view 100MB. I just dont want to care which qtree uses how much space - i just want to protect the system from having full volumes.

Re: one quota per volume not default quota and not per qtree?

I now spoke to two different NetApp Engineers, who told me, that this is not possible.

For using this with CIFS Shares I should: create a volume with one qtree (quota to this qtree) and place additional folders in this qtree/share. So build the multiple "shares" with folders on cifs level.

This works but I have to migrate tons of data to solve my problem.
