zfs discuss - Aug 2009 - change raidz1 to raidz2 with BP rewrite?

Will BP rewrite allow adding a drive to raidz1 to get raidz2? And how is status
on BP rewrite? Far away? Not started yet? Planning?

BP rewrite is an important component technology, but there''s a bunch  
beyond
that. It''s not a high priority right now for us at Sun.

What''s the bug / RFE number for it? (So those of us with contracts can
add a request for it.)

Adam,
Thanx for your answer. I often read your blog. :o)

Anyway, will it be possible to change from raidz1 to raidz2? I am switching to
raidz2 because if a drive fails, there is a high chance that another drive fails
while rebuilding the zpool (Ive heard).

I want to know my options to migrate to raidz2. Will I be able to turn raidz1
into raidz2, later? (My time horizon is 1-2 years)

I don''t have the number handy, but while it might be satisfying to add
another
request for it, Matt is already cranking on it as fast as he can and  
more
requests for it are likely to have the opposite of the intended effect.
