The beauty of ZFS is the flexibility of it's implementation. By supporting
multiple log device types and configurations it ultimately enables a broad
range of performance capabilities!

So now I have to ask, should I go with the OpenSolaris (.com) release

(Mostly in relation to SATA controllers)
Not sure if this is the right place to post this but since my main
goal is a ZFS server then I should get your guys opinions.

Hi, I'm running snv_78 on a dual-core 64-bit x86 system with 2 500GB usb
drives mirrored into one pool.
I did this (intending to set the rdonly flag after I copy my data):
zfs create pond/read-only
mkdir /pond/read-only/copytest
cp -rp /pond/photos/* /pond/read-only/copytest/
After the copy is c
I went ahead and bought a M9N-Sli motherboard with 6 sata controllers and also
a promise tx4 (4x sata300 non-raid) pci controller. Anyone know if the tx4 is
suppoerted in OpenSolaris? If it's as badly supported as the (crappy) Sil

email aren't posted on this forum..?? Or do I just get a copy

Hmm.. Thanks for the input. I want to have the most space but still need a raid
in some way to have redundancy.
I've added it up and found this:
ggendel - your suggestiong makes me "loose" 1TB - Loose 250GBx2 for the raid-1
ones and then 500GB from a 3x500GB = 1TB
bonwick - your first suggestion

hard to admin) - Would I be able to join the two RAIDz together for one BIG
volume altogether? And it will survive one disk failure?
