Also, ZFS does things like putting the ZIL data (when not on a dedicated
device) at the outer edge of disks, that being faster.
No, ZFS does not do that. It will chain the intent log from blocks allocated
from the same metaslabs that the pool is allocating from.
This actually works out well be
My answer is incomplete.
You can use the zpool attach command to attach another disk

the smaller disk is detached.

Hi Tim, that doesn't help in this case - it's a complete lockup apparently
caused by driver issues.
However, the good news ofr Insom is that the bug is closed because the problem
now appears fixed. I tested it and found that it's no longer occuring in

Hi--
Unfortunately, you cannot change the partitioning underneath your pool.
I don't see any way of resizing this partition except for backing up
your data, repartitioning the disk, and reinstalling Opensolaris

Maybe someone else has a better idea...
