Hey
Thanks for your answers guys.
I'll run VTS to stresstest cpu and memory.
And I just checked the block diagram of my motherboard (Gigabyte M61P-S3).
It doesn't even have 64bit pci slots.. just standard old 33mhz 32bit pci ..

Hmm, two thoughts on this:
1. For anyone interested, didn't VMS do something like this? Perhaps
a look at its design and implementation would be useful here.
2. For the per-application issue, there are ways to handle that.
First, make a ZFS api for providing file-level snapshots. Then, a

Via interposers, most likely.
It's in the kernel so it didn't need to interpose; it just has that

Not POSIX compliant, but that's how it is.

I've just started using zfs. I copied data from a ufs filesystem on
disk 1 to a zfs pool/filesystem on disk 2. Can I add disk 1 as a mirror
for disk 2, and then remove disk 2 from the mirror, and end up with all
the data back on disk 1 in zfs (after some amount of time, of course)?
If disk 1 is
Yes. Just say this:
# zpool replace mypool disk1 disk2
This will do all the intermediate steps you'd expect: attach disk2
as a mirror of disk1, resilver, detach disk2, and grow the pool
to reflect the larger size of disk1.

So, I set utf8only=on and try to create a file with a filename that is
a byte array that can't be decoded to text using UTF-8. What's supposed
to happen? Should fopen(), or whatever syscall 'touch' uses, fail?
Should the syscall somehow escape utf8-incompatible bytes, or maybe
replace them with ?s
