Hi all.

We currenty move out a number of iSCSI servers based on Thumpers 
(x4500) running both, Solaris 10 and OpenSolaris build 90+. The 
targets on the machines are based on ZVOLs. Some of the clients use those 
iSCSI "disks" to build mirrored Zpools. As the volumes size on the x4500 
can easily be grown I would like to know if that growth in space can be 
propagated to the client zpools without the need for resyncing. Destroying 
the iSCSI targets is just fine as is importing/exporting pools.

So far I managed to track the problem down to the "good old partition 
table" created by fdisk that seems to be one root cause for not seeing the 
added space after recreating the targets. The later was necessary to make 
sure the disk size matches the ZVOL size

Any hints are greatly appreciated!
Thomas
