CentOS - Feb 2007 - CentOS 4.4 lvm and drbd 0.8?

I'm running CentOS 4.4 and drbd 0.7 with ext3 filesystems on the drbd 
device.  I'm very interested in moving to drbd 0.8 and pulling my all of 
my drbd devices into one lvm for greater flexibility in filesystems.  
I've seen some notes on doing this but wonder if anyone on this list has 
a cookbook for doing this.  Also noted that on the drbd site the only 
packages they have are set up for the 2.6.9-34.106 kernel.  Any thoughts 
on when there might be a drbd .8 package for the current kernel?

Thanks for any wisdom on this,
Chuck

I am not quite sure that drbd-8 is totally ready yet for prime time.
Not that I don't trust them (I use drbd in production and I love it),
but I want to wait for an 8.0.1 or 8.0.2 level before I move the
enterprise CentOS RPMS to that version.

I would be open to producing some 8.0.0 rpms for testing ... though that
will probably need to wait until after CentOS 5 Beta is released.

Thanks,
Johnny Hughes

Makes sense to me, I'll try to be patient ;-)

Could you get the same effect by running software RAID1 with one of the 
drives connected via iscsi?
