Any advise about the RAM I need on the server (actually one MD1200 so 12x2To
disk)

Well, my employer is not so rich.
It's first time I'm going to use ZFS on FreeBSD on production (I use on my
laptop but that's mean nothing), so what's in your opinion the minimum ram
I need ? Is something like 48

ll /dev/da0 --> /dev/da47.
I've create a zpool with 4 raidz2 (one for each MD1200).
After that I re-install the server (I put some wrong swap size), and I
don't find my zpool at all.
Is that normal ?
Regards.

what I understand I can add more more MD1200. But if I loose one MD1200
for any reason I lost the entire pool.
In your experience what's the «limit» ? 100 disk ?
How FreeBSD manage 100 disk ? /dev/da100 ?
Regards.

to migrate all data on those 12 old disk on the new and remove those old

I can force this with «-f» option.
But what's that mean (sorry if the question is stupid).
What's kind of pool you use with 46 disk ? (46=2*23 and 23 is prime number

ou think of the perf ?
The purpose is make a big NFS server with primary data on a high-level raid
array disk but using ZFS to mirror all data on the all old-raid-array.
