zfs discuss - May 2008 - >1TB ZFS thin provisioned partition prevents Opensolaris from booting.

Not sure where to put this but I am cc''ing the ZFS - discussion board.

I was successfull in creating iscsi shares using ZFS set shareiscsi=on with 2
thin provisioned partitions of 1TB each (zfs create -s -V 1tb idrive/d1). Access
to the shares with an iscsi initiator was successful, all was smooth, until the
reboot.

Upon reboot, the console reports the following errors.

WARNING: /scsi_vhci/disk at g0100015c55fb40900002a00483e34c6 (sd9): 
    disk has 3221225472 blocks, which is too large for a 32-bit kernel
WARNING: /iscsi/disk at
0000iqn.1986-03.com.sun%3A02%3Aee2143f2-f5ce-6414-fcda-8035dacfc3730001,0
(sd10):
   disk has 3221225472 blocks, which is too large for a 32-bit kernl

And it continues to do this on the other partition i had created.

Ultimately coreadm:default fails bad
and the server is stuck at
svc.startd[7]: Lost repository event due to disconnection.

I am on a Poweredge 2650 with 2xXeon Processors @2.8GHZ
1.5 GB Ram
Running Opensolaris 2008.05 

Anyideas, or is ZFS partition greater than 1 tb on a 32bit kernel  not possible.
Do I have to move to 64 bit Solaris?

You''ll have to move to 64bit Solaris. There''s only so much
that you can do when you''re running in 32bit mode.
