Re: [zfs-discuss] change raidz1 to raidz2 with BP rewrite?

2009-08-30 Thread Orvar Korvar
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)

Hi David,

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.)


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.

Adam

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?
