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

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

I agree on the motherboard and peripheral chipset issue.
This, and the last generation AMD quad/six core motherboards all seem to use
the AMD SP56x0/SP5100 chipset, which I can't find much information about
support on for either OpenSolaris or FreeBSD.
Another issue is the LSI SAS2008 chipset

I'm no expert in this subject, but I do feel confident in my knowledge
that
the license conflict is just one of many obstacles to prevent ZFS from
working nicely in Linux.

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
