If you are attaching a new enclosure, make a new zpool in that enclosure with a
temporary name and 'zfs send' snapshots from the old pool to the new pool,
reading in with 'zfs recv'.

When viewing a raidz|raidz1|raidz2 pool, 'zpool list|status' will report the
total "device" space; ie: 3 1TB drives in a raidz will show approx. 3TB space.
'zfs list' will show available FILESYSTEM space, ie: 3 1TB raidz disks, approx
2TB space.

Hi Chris,
It sounds like there is some confusion with the recommendation about raidz?
vdevs. It is recommended that each raidz? TLD be a "single-digit" number of
disks - so up to 9. The total number of these single digit TLDs is not
practically limited.

Try fmdump -e and then fmdump -eV, it could be a pathological disk just this
side of failure doing heavy retries that id dragging the pool down.

data currently would be quite
efficient, but there is one pathology in current ZFS which impacts this
somewhat, last time I looked each ARC ref to a de-duped block leads to a
inflated ARC copy of the data, hence a highly ref'ed block (20x for instance),
could exist 20x in an inflated state in AR

dd larger disks to a mirrored pool, you can replace the mirror
members, one at a time, with the larger disk and wait for resilver to
complete. Then replace the other disk, resilver again.

I have had a brief introduction to ZFS and while discussing it with some other
folks the question came up about use with multipathed storage. What, if any,
configuration or interaction does ZFS have with a multipathed storage setup -
however it may be managed.

I just stumbled across a clever visual representation of deduplication:
http://loveallthis.tumblr.com/post/166124704
It's a flowchart of the lyrics to "Hey Jude". =-)
Nothing is compressed, so you can still read all of the words. Instead, all of
the duplicates have been folded together. -ch
Great stuff, Jeff and company. You all rock. =-)

I am also accustomed to seeing diluted properties such as compressratio. IMHO
it could be useful (or perhaps just familiar) to see a diluted dedup ratio for
the pool, or maybe see the size / percentage of data used to arrive at
dedupratio.
As Jeff points out, there is enough data available to
Mike, I believe that ZFS treats runs of zeros as holes in a sparse file, rather
than as regular data. So they aren't really present to be counted for
compressratio.

http://mail.opensolaris.org/pipermail/zfs-discuss/2008-April/017565.htm
I take your point Mike. Yes, this seems to be an inconsistency in accounting.
I have simply become accustomed to this (esp. when dealing with virtual disk
images), so I just don't think about it, but it *is* harder to balance accounts.
For instance, if my guest cleans up it's vdisk by writing
