Set a directory quota on an OES11 – NSS volume using a command line.

Disk Quotas is the most natural starting point in building a solid storage strategy. Setting quotas will easily let you:
– Show users what reasonable storage use is – define an upper limit.
– Allow storage to grow in a controlled and sustainable manner.
– Promote efficient usage and streamline backup/restore times.

This script will set a quota directory on the Novell Storage Services for Novell Open Enterprise Server 11.

Usage:

./sdq.sh /media/nss/VOLUMENAME size

Please, mind that the size must be in KB! The quota will be set to all directories on the HOME volume. If you do not want to set a quota for a particular directories, please add them to:

/etc/sysconfig/excludefromsdq.conf

in the form:

/media/nss/VOLUMENAME/directoryname/
/media/nss/VOLUMENAME/directory name 1/

Please, mind that the forward slash at the end of each line is required.

Okay, so now on you know how to use this script. Let say that you need to set a directory quota on OES11 server on NSS volume for about thousand directories in the form:

current size of a directory + 500MB and 500MB for directories which current size is lower than 500MB, so to do that please type the following:

sdq.sh /media/nss/HOME 500000

nbfs4:~ # sdq.sh /media/nss/HOME 500000
Running with the following options: ./sdq.sh /media/nss/HOME 500000
File /etc/sysconfig/excludefromsdq.conf exists.

500000 is greater than data 189952
Directory Quota on “/media/nss/HOME/desktop”:
quota : Unlimited
spaceUsed : 0.00 KB
Set quota for /media/nss/HOME/desktop/
Directory Quota on “/media/nss/HOME/desktop”:
quota : 488.28 MB
spaceUsed : 185.50 MB
Quota set to 500000 KB
Directory Quota on “/media/nss/HOME/desktop”:
quota : 488.28 MB
spaceUsed : 185.50 MB
Done for /media/nss/HOME/desktop/

Directory /media/nss/HOME/dontchange/ is excluded from quota
Directory Quota on “/media/nss/HOME/dontchange”:
quota : Unlimited
spaceUsed : 0.00 KB

Size of data 3741492 is greater than 500000
Directory Quota on “/media/nss/HOME/GW”:
quota : Unlimited
spaceUsed : 0.00 KB
Set quota for /media/nss/HOME/GW/
Directory Quota on “/media/nss/HOME/GW”:
quota : 4.05 GB
spaceUsed : 3.57 GB
Quota set to 4241492 KB
Directory Quota on “/media/nss/HOME/GW”:
quota : 4.05 GB
spaceUsed : 3.57 GB
Done for /media/nss/HOME/GW/
