zfs code - Jun 2006 - ztest not resilvering with 20060605 sources?

Hi again,

I think I found another problem in the current (20060605) sources. I was 
running ztest for about 2 hours and I started checking the pool layout 
with ''zdb -U -s ztest'' at the same time. I noticed that none
of the replacing
vdevs were disappearing, even after an hour.

By the way, I believe ztest was running with the default
''vdev_attach_detach =
rarely''.

Could you try to reproduce this in OpenSolaris? My Nexenta system seems to be 
working correctly, but it''s using an old build (OpenSolaris Build #36).

To be sure it wasn''t a Linux port specific bug, I reverted the source
back to
20060519 and now it seems to be working correctly. I haven''t tried to
analyze
the problem.

Here''s an output of the misbehaving test, after about 3 hours of ztest
(with
lots of replacing vdevs):

Nevermind, I think the resilvering is working.. (otherwise I wouldn''t
have
files ending in b).

But it sure is slow.. is this normal?
