quotas?


Recommended Posts

Posted

I need to limit an nfs share for a particular user to 200 GB.  I created a dedicated username and was trying to find a way to set a quota, but failed in my effort.

 

Using unRAID server pro 5.0.6 right now.

 

The reason I need the quota is a firmware bug in my new Hikvision IP camera.  It is allergic to shares over 200 GB.

 

Could also use SMB, if that is easier.

No unRAID feature for that. You could add a drive to the array that was that small or smaller and restrict a share to that drive. Maybe hard finding an HDD that small now but SSDs will work.

Are you saying it is impossible even from the command line?  This has been a feature of *nix since before the Carter presidency.

If you are clever enough maybe you can do it from the command line. I don't know. It is not a feature of unRAID. The users defined in the unRAID webGUI can't even login to the command line. They can own files, but can only access them over the network.

You could fill a larger disk with lots of other media in a different share, all but 200G. Then configure the share properly, and achieve this result.

 

Not sure this is helpful.

If you have a spare drive, you can create a 200GB partition and share with this plugin: https://lime-technology.com/forum/index.php?topic=38635.0

But you would have to be on v6.

 

Another thing you could probably do along those lines if you're good with Linux. I'm not but I have seen bits and pieces on the forum.

 

Partition a drive with 200GB and another partition to use the rest of the drive if you wanted. You couldn't use this in the array, but you could probably mount each partition and share them using smb-extra.conf

 

The mounting would have to be redone on bootup using the go script. Probably got some of this wrong, and can't really help on the details without doing some research myself, so will leave that to you or maybe one of the real experts will chime in.

could you create a share, limited to one disk that had a minimum space free:

eg 1TB disk with minimum space 800GB

 

Other shares could also use the drive so it isn't wasted space?

(or is this an unpaid 6 only option?)

No that is in v5, but it's the same idea dgaschk had. In the end, any other share using that drive would impact the "quota". In your example, if another share wrote 100GB to the drive, then the disk would have 900GB free, so the "quota" would shrink to 900GB - 800GB = 100GB.

 

And so on.

The 200GB partition idea should work though.  I don't know how big your Cache drive is, but if it's 500GB or more, you could shrink the first partition by 200, then carve a new one at the end, size 200GB.  It will have to be mounted through the command line only though, and you may have to run reiserfsck on the Cache partition to correct its file system size (not sure).

Having the exact same issues with hikvision cameras and Unraid.

The issue is basically with Hikvision but considering they haven't solved it in years, i doubt much progress will happen there. I've literally found hundreds of user postings on this issue. It's rather appalling Hikvision doesn't seem to care. These are not cheap cameras.

 

Having "Quota" available in the Unraid build would help a lot already as i would be able to restrict a user/share by quota then.

Exact same issue here also with Hikvision cameras, would be really nice if we had the ability to either have user quotas or the ability to customize a user share reported volume size (regardless of the physical disk size used).

Posted

Thanks for the suggestion. I would consider that option, however with each camera requiring it's own unique share, dedicating a physical drive for every camera is a showstopper unfortunately.

I can confirm that Hikvision IP cameras need quotas.  Their logic is essentially to pre-fill the storage you give them with sparse files... and they fill it up till full.... so you need to set some reasonable quota to stop an entire drive/share from being filled.

Is this likely to work on unRAID?

 

## Create an image file to your preferred size

fallocate -l 50G /data/security/patio.img

 

## Format the image file as ext3

mkfs -t ext3 -q /data/security/patio.img -F

 

##Add the NFS mount to your FSTAB to mount the image at your NFS location (/etc/FSTAB)

/data/security/patio.img /data/security/patio ext3 rw,loop,usrquota,grpquota 0 0

What am I doing wrong?  File size is zero.  Prior to this I stopped the array, unmounted everything, then created a mount point and mounted the drive under /mnt/disk2.

root@tower:/mnt/disk2/cameraBasementStairs# fallocate -l 50G ./cameraBasementStairs.img

root@tower:/mnt/disk2/cameraBasementStairs# ls -lh

Is the disk XFS?

 

 


root@rack:/mnt/disk8# ls
root@rack:/mnt/disk8# du -a
0   .
root@rack:/mnt/disk8# fallocate -l 50GB stor.img
root@rack:/mnt/disk8# ls -l
total 48828128
-rw-r--r-- 1 root root 50000000000 Sep 13 12:58 stor.img
root@rack:/mnt/disk8# du -a
48828128   ./stor.img
48828128   .
root@rack:/mnt/disk8#

It is whatever Unraid Server Pro 5.0.6 defaults to.  The disk it is on is part of the array, if that is what you are asking.

 

In any case, I ended up creating a 50 Gig file full of zeros using dd.  Then I put an ext3 filesystem in the file.

 

How would I export that file through NFS?  I have tried mounting it in fstab, and exporting it via NFS in /etc/exports, but somehow fstab gets overwritten when I reboot.
