I recently upgraded my home server from 9.0 to 9.1, actually, I did exported my
data zpool (raidZ2), did a clean installation of 9.1, then imported my data
zpool. Everything went perfectly

I ran many ZFS pools on top of hardware raid units, because that is what we

Your hardware raid should be faster than ZFS raid. Don't use zfs raid
because there will be no benefit. You'll get the performance of
software raid using CPU time, along with lost space for already backed
up data.

Hi,
I have a question regarding ZFS install on a system setup using an Intel
Modular.
This system runs various flavor of FreeBSD and Linux using a shared pool
(LUNs).
These LUNs have been configured in RAID 6 using the internal controller (LSI
logic).
So from the OS point of view there is
17 matches
