Is it possible to limit folder size in NexentaStor Community Edition

  • 772

For example if i have a 4TB ZFS Volume, is it possible to create 3 folders and then limit each folder to, say, 2GB. If so, how?

I have googled hard and wide but to no avail - all i get is info on the 18TB license restriction.

All and any advice gladly taken.

---EDIT

After testing all the below answers worked, I'm giving my correct answer to GUI related answer as i feel its the most correct solution to the problem, however the rest are useful to read.

nfs zfs nexenta

    In the web GUI, navigate to Data Management -> Shares and select the necessary folder.

    Under Read-Write Parameters, you can enter a quota to limit to how much space the folder can consume (Referenced Quota), or how much the folder and its snapshots, etc. can take (Quota). The normal suffixes (G,M,K) apply.

  2. What you were looking for is the "quota" feature of zfs.

    To set a 2GB quota on dir/whereever in a pool named pool:

    zfs set quota=2G pool/dir/whereever

    And, to check a quota:

    zfs get quota pool/dir/whereever

  3. In the NMS admin panel, you can set this via going to Data Management -> Data Sets -> Folders -> Show -> -> Quota

    enter image description here

    This is essentially the same thing as "zfs set quota". Note the quota applies to that entire ZFS filesystem (or Folders), not just within specified folders. If you need different quotas, you'll have to use different filesystems.
