recently we have been getting a space issues on our unix server.
we are looking to formulate a plan to limit the space per user.
In the recent space issues,we had some users who were running very big jobs and because of that it is affecting the entire
file system on our server.there is no limit is there for any user for space.
so can we impelement this.
what are the different sas users and limiting space to the user means how much should we allocate based on their role.
please can any one through some ideas or your experience on this.

Does the space issue relate only to SAS WORK library space or does it also include permanent SAS libraries? Please clarify.
If this is only about SAS WORK library space, then for starters there should be a limit on the total WORK space available to all users before considering individual limits. It is important that total WORK space has a limit so it doesn't impact other disk usage.

The issue is related only to saswork and we do got got space issues in the past for /var /usr and other /sas file systems.
but right now we want to limit the space to the users according to their role.so how from where should i start with this.
I want to formulate a plan for this please.
when we are saying limiting space per user what are types of users will be there and for each category how much space we can allocate
please suggest me.

As a simple example this is how I would approach it:
Firstly I would allocate a limit for the total WORK space lets say 500GB (gigabyte).
Secondly if the maximum number of SAS users using SAS at the same time is 20, I would set a user limit of 25GB (500/20).
It is highly unlikely that all users will use their maximum space at the same time. But let's say 10 use the maximum so that leaves 250GB for the remaining users.
If your maximum number of users at the same time suddenly goes up to 40, then the 500GB limit on total WORK space will protect the rest of your file system from being filled up.
These numbers are not recommendations for you as I don't know what your WORK space requirements are - how much space you have, how many simultaneous users you have, what your typical WORK dataset sizes are, how much on average each user might use etc.

we have 15 TB of space allocated for our sas, and our quota system has been removed.
There is no quota for our file mountings.
This is how our file system has been setup
zsasrd 8.94T 5.73T 21K /zsasprd
zsasrd/sas 2.85T 5.73T 2.85T /sas
zsasrd/sas-sasconfig 30.7G 5.73T 30.7G /sas/sasconfig
zsasrd/sas-saseg 901G 5.73T 901G /sas/saseg
zsasrd/sas-oracle 5.33G 5.73T 5.33G /sas/oracle
zsasrd/sas-home 6.91G 5.73T 6.91G /sas/home
zsasrd/sas-sasutil 54.2M 6.46T 54.2M /sas/sasutil
zsasrd/sas-saswork 157G 6.31T 157G /sas/saswork
zsasrd/sas-saswork-meta 60K 5.73T 60K /sas/saswork/meta
we have 250 sas users overall,actively 100-150 users will run reporrts,most of them run reports
when we are saying limiting space per user what are types of users will be there in sas and for each category
like for eg : power users,simillary who are other type of users
