Can I go to an existing xfs file system, and apply a soft quota to each user on it? If I do, can I then run a report, and see who's using how much, or does it only apply to files created after the quotas are applied? mark

For those who already have some limits set you can still can change these limits, but with individual command, say in the loop, like: for i in `cat user_list`; \ do xfs_quota -x -c "limit bsoft=8g bhard=10g $i; \ done I hope, this helps.
