This is simply not true. ZFS would protect against
the same type of
errors seen on an individual drive as it would on a
pool made of HW raid
LUN(s). It might be overkill to layer ZFS on top of a
LUN that is
already protected in some way by the devices internal
RAID code but it
does
There are also the speed enhancement provided by a HW
raid array, and
usually RAS too, compared to a native disk drive but
the numbers on
that are still coming in and being analyzed. (See
previous threads.)
Speed enhancements? What is the baseline of comparison?
Hardware RAIDs can be
AFAIK, no. The attach semantics only works for
adding mirrors.
Would be nice if that can be overloaded for RAIDZ.
Sure would be.
Not sure exactly which blog entry but you might be

sized disks). The

I recently used a set of 6 disks in a MultiPack to create a RAIDZ volume. Then
I proceeded to do zfs set sharenfs=root=a.b.c.d:a.b.c.e space (space is how I
named the ZFS pool).
Then I NFS mounted the ZFS pool on another system, and proceeded to do a find +
