[OmniOS-discuss] changing sector size for pool

[Doug Hughes]

When this pool was setup, it was with a different controller that didn't 
support > 2TB / disk. When the controller was replaced, the pool is 
still set for ashift=9, but if I try to replace a disk in it with 
another disk of exactly the same model I get the annoying error:

root at x4275-3-15-22:/root# zpool replace zpool1 c0t5000CCA22BC8F4C2d0 
c0t5000CCA3DE1719Fd0
cannot replace c0t5000CCA22BC8F4C2d0 with c0t5000CCA23DE1719Fd0: devices 
have different sector alignment

I know there's a -o ashift=9 option for Linux. Is there some sort of 
equivalent action that I can take, perhaps upgrading the existing zpool 
without having to recreate it?

Thanks
