What OS/distro are you using on the server?
Sorry (hides face in shame). I'm using Ubuntu Breezy. I plan on building
my own 2.6.16 kerenel. So my choices are li,ited to what's avaialble
on Linux.
I would think BTW, that if i had managed to get my hardware working
with Solaris 10 (which was my first plan), I'd have used zfs.
Solaris for x86 has always been short in the hardware department...In past
days it was kinda sluggy too because it lacked hardware support for a
number of things that were fast on SPARC due to hardware support in the
processor. I think with 10 they finally became VERY serious about x86 and
ESPECIALLY x86_64 performance too and it's improved, that said I haven't
had any time to even test Sol 10. Soon...sometime...
I'd tend to recommend ReiserFS or XFS first (to me Reiser is better, XFS
second...Reiser seems to handle corruption a little better, except in the
case of tail corruption in which case you lose all the tails on the
filesystem possibly), followed by ext3. Ext2 isn't an option because for
500+G you need journalling.
Reiser will take a while to mount such a large filesystem....As may XFS. I
haven't treied anything that big recently with ext3 but you can try
it...though I'm kind of interested now so I might see myself. My
benchmarks would be out of whack with yours though because of CPU and
storage backend differences. :)
