Hello everybody,
is there a way to compute very quickly some hash of a file in a zfs?
As I understand it, everything is signed in the filesystem, so I'm wondering if
I can avoid reading whole files with md5sum just to get a unique hash. Seems
very redundant to me :)
Bottom line is I want to mak

Is there a O(nb_blocks_for_the_file) solution, then?
I know O(nb_blocks_for_the_file) == O(nb_bytes_in_the_file), from Mr. Landau's
POV, but I'm quite interested in a good constant factor.

I'd be more concerned that the motherboard and it's attached
peripherals are unsupported than the processor. Solaris can handle
I agree on the motherboard and peripheral chipset issue.
This, and the last generation AMD quad/six core motherboards all seem to use

the onboard sata is a secondary issue. If i need to, i'll boot from the
oboard usb slots. I have 2 LSI 1068e based sas controllers which i will be
using.

I was having quite a bit of problems getting the rpool mirroring to work as
expected.
The issue I have is not about the how to create mirror rpool. I got sufficient
information from the various good people in the internet to do this correctly.
I am not sure the specific I have here is related t
Well i went ahead and ordered the board. I will report back soon with the
results..i'm pretty excited. These CPU's seem great on paper.

It would be nice to have a grub menu item that ignores the cache, so
if you know you've removed a USB drive, you don't need to muck about

I'm looking for input on building an HA configuration for ZFS. I've read the
FAQ and understand that the standard approach is to have a standby system with
access to a shared pool that is imported during a failover.
The problem is that we use ZFS for a specialized purpose that results in 10's
