I'm trying to provide some disaster-proofing on Amazon EC2 by using a

My aim is to ensure that, should the instance terminate, a new instance can
spin-up, attach the EBS volume and auto-/re-configure the zpool.

One thing I've just noticed is that after a reboot of the new instance, which
showed no data on the EBS volume, the files return. So:
1. Start new instance
2. Attach EBS vols
3. `ls /foo` shows no data
4. Reboot instance
5. Wait a few minutes
6. `ls /foo` shows data as expected
Not sure if this

Hi,
I am playing with opensolaris a while now. Today i tried to deduplicate the
backup VHD files Windows Server 2008 generates. I made a backup before and
after installing AD-role and copied the files to the share on opensolaris
(build 134). First i got a straight 1.00x, then i set recordsize
Bogdan,
Thanks for pointing this out and passing along the latest news from Oracle.
Stamp out FUD wherever possible. At this point, unless it is said officially,
and Oracle generally keeps pretty tight lipped about products and directions,
people should regard most things as heresy.
Cheers,
You might note, dedupe only dedupes data that is writen after the flag is set.
It does not retroactivly dedupe already writen data.

A few things come to mind...
1. A lot better than...what? Setting the recordsize to 4K got you some
deduplication but maybe the pertinent question is what were you
expecting?
2. Dedup is fairly new. I haven't seen any reports of experiments like
yours so...CONGRATULATIONS!! You're probably
Dedup is a key element for my purpose, because i am planning a central
repository for like 150 Windows Server 2008 (R2) servers which would take a lot
less storage if they dedup right.
