Hi guys, I am about to reshape my data spool and am wondering what
performance diff. I can expect from the new config. Vs. The old.
The old config. Is a pool of a single vdev of 8 disks raidz2.
The new pool config is 2vdev's of 7 disk raidz2 in a single pool.
I understand it should be

I'm currently planning on running FreeBSD with ZFS, but I wanted to
double-check how much memory I'd need for it to be stable. The ZFS
wiki currently says you can go as low as 1 GB, but recommends 2 GB;
however, elsewhere I've seen someone claim that you need at least 4 GB.

How did it turn out ? Did 8x1TB Drives seem to be the correct number or a
couple too many (based on
the assumption that you did not run out of space; I mean solely from a
performance / 'ZFS usability'
standpoint -
Bump.
Some of the threads on this were last posted to over a year ago. I checked
6485689 and it is not fixed yet, is there any work being done in this area?
Thanks,

There may be some work being done to fix this:
zpool should support raidz of mirrors

Hi All
Is there any hope for deduplication on ZFS ?

There is always hope.

a lot of choices
Though possible, I don't think we would classify it as a best practice.

Solaris will allow you to do this, but you'll need to use SVM instead of ZFS.
Or, I suppose, you could use SVM for RAID-5 and ZFS to mirror those.

Or run Linux ...
Richard, The ZFS Best Practices Guide says not.
Do not use the same disk or slice in both an SVM and ZFS

OK. Seems odd that ZFS would allow that (would people want that configuration
