I have set up quotas on Linux on a ext3 filesystem. I have set a soft block limit of 1GB, no hard limit and no inode limits.
For users over quota, the summary listing (the one showing all users quotas for the selected filesystem) is incorrect. It shows "used inodes = 0", "inode soft limit" in the range of 3 to 6 and "grace time = 0". The listing of all quotas on all filesystems for this specific user is correct (used inodes, unlimited soft/hard limit and empty grace time), as is the output of 'edquota -u <user>'
