The quota doesn't report a warning message even if a soft limit is exceeded.

Solution Verified - Updated -

Issue

  • The quota doesn't report a warning message even if a soft limit is exceeded.
  • We ran edquota so as to set both a soft limit and hard limit for an user.  We logged-in to our own system as the user, and then used a limited disk until the soft limit is exceeded.
  • Since the soft limit was exceeded, the quota should have reported a warning message, but didn't do that.

  • On RHEL5, the quota works correctly.  When we did the same step as  "Step to Reproduce" on RHEL5, the quota reported the following warning message.

    <device-name>: warning, user block quota exceeded.

  • The expected behavior is that the quota reports the above warning message on RHEL6 in the case.  But it doesn't do that.

  • Step to Reproduce:

  1. Edit the file /etc/fstab as follows.
    • /dev/sdb1  /quotatest ext2 defaults,grpquota,usrquota 1 2
  2. Create a mount point. 
    • # mkdir /quotatest
# chmod 777 /quotatest
  3. Run the mount command so as to enable the above Step 1. 
    • # mount -a
  4. Enable the quota by using following commands. 
    • # quotacheck -cugv /quotatest/
# quotaon -a
  5. Create a test user. 
    • # useradd quotatest
  6. Set both a soft limit and a hard limit for the test user. 
    • # repquota -v /quotatest
    *** Report for user quotas on device /dev/sdb1
    Block grace time: 7days; Inode grace time: 7days
                            Block limits                File limits
   User            used    soft    hard  grace    used  soft  hard  grace
   ----------------------------------------------------------------------
   root      --    2880       0       0              3     0     0       
   quotatest --       0    1024    2048              0     0     0

    • <We set 1024 Kbyte to a soft limit, and set 2048 Kbyte to a hard limit.>

  7. Login to the system as the test user. 
    #su quotatest
  8. Use the limited disk until a soft limit is exceeded.
 $ dd if=/dev/zero of=/quotatest/test bs=1024 count=512
 <shouldn't report a warning message>

 $ dd if=/dev/zero of=/quotatest/test2 bs=1024 count=512
 <should report a warning message>
  • Actual Results:
    • The quota doesn't report a warning message even if a soft limit is exceeded.
  • Expected Results:
    • The quota reports a warning message if a soft limit is exceeded.
