Hello,

When I set refquota on a dataset, write IOs are done very sloooowwwly =
some MB below the limit.
And I can't manage to reach it, dd (used to create a file to fulfil =
space) seems to stall.

No problem however with quota, dd goes to the end and returns with :
"Disc quota exceeded"

Any clue ?
I would have been interested to use refquota to avoid impacting users =
with snapshots'fs space, but this option is quite unusable as is.

Thank you very much !

Ben
