CentOS - Aug 2018 - xfs quota question

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?

After remounting XFS filesystem with option "usrquota" you can issue
the
command similar to:

xfs_quota -x -c "limit bsoft=8g bhard=10g -d" /home

This command will enable the limits above for all users (-d flag), 
except users who have their limits existing already (usually ones who 
preformed fs operations).

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.

Will that work if I do a mount -o remount?
