Enable File System Quota On Debian








 

  • For example we want to apply disk quota on /dev/md5 to each user, say 2000MBytes soft limit & 2500MB/2.5GB hard limit.
  • 1. install quota package
    • sudo apt-get install quota
  • 2. edit /etc/fstab to enable quota on /dev/md5 file system
    • /dev/md5 /home ext3 defaults,usrquota,grpquota 0 2
  • 3. re-mount /dev/md5
    • sudo mount -o remount /home
  • 4. edit user quota one by one
    • sudo edquota -u tom -f /dev/md5
Disk quotas for user tom (uid 3050):
Filesystem blocks soft hard inodes soft hard
/dev/md5 0 2000000 2500000 0 0 0


* the above assigns 2000000KB/2GB soft limit and 2500000/2.5GB hard limit to user tom.




  • 5. set grace period to 0seconds

    • sudo edquota -t -f /dev/md5





Grace period before enforcing soft limits for users:
Time units may be: days, hours, minutes, or seconds
Filesystem Block grace period Inode grace period
/dev/md5 0seconds 0seconds



  • 6. disable then re-enable the quota to make it work

    • sudo quotaoff -a


    • sduo quotaon -vug /dev/md5


      • on error:see this


        • quotaon: using /home/aquota.user on /dev/md5: Invalid argument


        • quotaon: using /home/aquota.group on /dev/md5: Invalid argument




      • quotacheck -vugm /dev/md5






  • 7. to list the current quota settings

    • repquota -a
