In Solaris, system administrator can control the size of the UFS file system by limiting the amount of disk space using quota. For this reason, quotas are especially useful on the file systems where user home directories reside. As a rule, public and /tmp file systems usually do not benefit as much from the establishment of quotas.
Take a look at my example..
root@fileserver # df -h

There are 30 users will be using the /data directory. Each of the them will have 5GB disk space. To implement the quota on /data slice, first you need to make a file called qoutas under /data directory
1. Change directory to /data
root@fileserver # cd /data
2. Create file called quotas
root@fileserver # touch quotas
3. Edit the /etc/vfstab file and add rq to the mount options field for each UFS file system that will have quotas.
root@fileserver # vi /etc/vfstab
/dev/md/dsk/d10 /dev/md/rdsk/d10/data ufs 3 yes rq4. Change permissions to read/write for root access only on quotas
root@fileserver # chmod 600 quotas
5. Set quotas for a user
root@fileserver # edquota kks
You'll see a file containing a description about the quotas allocation.
fs /files blocks (soft = 0, hard = 0) inodes (soft = 0, hard = 0)I'm gonna set the quotas for each user around 5GB each.
fs /files blocks (soft = 4500000, hard = 5000000) inodes (soft = 0, hard = 0)We call that user kks as a prototype to make another quotas for the rest of the users.
6. root@fileserver # edquota -p kks trs ppa djk bsk ksn opr usk ren umm sdm umn wem tek usy int mar lpn kmp spi kpi jal huk kpn jdi cmo kpd dlk pku drk
7. Check the quotas
root@fileserver # quotacheck -va
