We used ZFS like this on a Hitachi array for 3 years.  Worked fine, not
one bad block/checksum error detected.  Still using it on an old Sun 6120
array, too.


  It's too late to change my
 setup, but in the future when I'm planning new systems, should I consider the
 effort to allow zfs fully control all the disks? 

Well, you should certainly consider all the alternatives you can afford.
Our customers happen to like cheap bulk storage, so we have a Thumper,
and a few SAS-connected Sun J4000 SATA JBOD's.  But our grant-funded
researchers may not be a typical customer mix

[zfs-discuss] Zpool creation best practices

2009-12-30 Thread Mike
I'm just wondering what some of you might do with your systems.  

We have an EMC Clariion unit that I connect several sun machines to.  I allow 
the EMC to do it's hardware raid5 for several luns and then I stripe them 
together.  I considered using raidz and just configuring the EMC as a JBOD, but 
I thought it would defeat the purpose paying so much for a system with the 
advanced redundancy system.  I also like to add luns on the fly when a system 
needs more file space and I know you can't do that with raidz.  

I've never had a lun go bad but bad things do happen.  Does anyone else use ZFS 
in this way?  Is this an unrecommended setup?  It's too late to change my 
setup, but in the future when I'm planning new systems, should I consider the 
effort to allow zfs fully control all the disks?
