It is true, quota is in charge of logical data not physical data.
Let's assume an interesting scenario -- say the pool is 100% full in logical
data
(such as 'df' tells you 100% used) but not full in

Cindy,
Following is quoted from ZFS Dedup FAQ:
Deduplicated space accounting is reported at the pool level. You must use the
zpool list command rather than the zfs list command to identify disk space
consumption when dedup is enabled. If you use the zfs list command to review

I believe the quota applies to the non-dedup'd data size. If a user
stores 10G of data, it will use 10G of quota, regardless of whether it

That's correct. Although it can be turned off and on at the filesystem
level (assuming it is enabled for the pool).
If it can have fine-grained granularity(like based on fs), that will be great!
