Hi All,

Thanks for the recent info on my controller problems.  So now I'm taking a 
different approach but had a more basic question.

I have:
2x150GB SATA ii disks
2x500GB SATA ii disks

Is it possible/recommended to have something like a pool of two raidz pools.  
This will hopefully maximize my storage space compared to mirrors, and still 
give me self healing yes?

so something like createing:
zpool smallpool raidz  150a 150b
zpool mediumpool raidz 500a 500b
zpool joinedpool smallpool mediumpool ????possible

Or would it me safer/better to have two separate pools rather than trying to 
combine them?

assuming I can get the above into some kinda single pool, I have a few top 
level data folders that I would then create, ie Music, Video, Images, Pictures. 
 On my test system I was just creating these as folders with NFS shares to each 
folder.  Is there any advantage to using the zfs command rather than just plain 
folders besides being able to take a snapshot of a specific folder?

I also wanted to test a recovery of my pool, so my took two disk raidz pool 
onto a friends freebsd box.  It seems both systems use zfs version 6, but the 
import failed.  I noticed on the boot logs:

GEOM: ad6: corrupt or invalid GPT detected.
GEOM: ad6: GPT rejected -- may not be recoverable.

Is that a solaris or freebsd problem do you think?

Thanks in advance for any help!

Peter
