Subject: LVM2 stripes and mirrors

Hi!

I've got two questions concerning LVM2.

Number one: What stripesize parameter would you use? The manual of my 
mainboard advises to use 64k for a RAID-0. Would that be useful for my 
portage tree or a more conventional partition like /usr and /var?

Number two is not really a performance issue but it's LVM2-related: 
LVM2-mirrors need an extra log device but the man pages don't tell anything 
about how large it has to be or if it can be a partition or loop device on 
the same hdd as one of the mirrors.

Thanks in advance!

Florian Philipp
