USE THESE COMMANDS AT YOUR OWN RISK. IF YOU DON'T UNDERSTAND WHAT THEY DO, DO NOT USE THEM AND GO TO THE MAN PAGES!
If you see difference between disk usage and user quota usage, you can correct this by executing quotacheck command.
Here you have an example:
[aix:root:/DATA2:] [color=blue]find . -xdev -user data2user -type f -exec du -k {} \;|awk '{ s = s+$1 } END { print "Total used: ",s }'[/color]
Total used: 157160496
[aix:root:/DATA2:] [color=blue]quota -v data2user[/color]

To modify the user quota on a JFS2 fs, you must use j2edlimit command (for JFS you need to use edquota command)
Here you have example with JFS2 fs:
To list user quota for the filesystem:
