Jim,
There is no space constraints nor quotas...
Thanks,

There's nothing here that requires confidentiallity, and
the public alias is a much broader audience with a larger
number of experienced ZFS users...
As to the issue - what is the free space disparity
across the pools? Is the one particular pool significantly
tighter on free space than the other pools ("zpool list")?
Thanks,

Customer has many large zfs pools..He does the same on all pools:
Copying overnight large amounts of small files (1-5K).
All but one particular pool (that has been expanded) gives them this
problem:
--the copying within a few minutes crawls and the zpool looks
unresponsive.
Background:
He had to grow this particular pool twice over a period of time (it
was 6TB and it grew by 4TB twice-now it is 14TB)
Solaris was U4 but now is U6.
They have limited the arc:
set zfs:zfs_arc_max=0x100000000
and
zfs:zfs_nocacheflush=1 (they have a 6540 array).
Does expanding the pool affects performance and if so what is the
best way to recover
(other than rebuilding the pool)
Thanks,
