Thanks for the input. Some responses:

@hicksd8. Neither disk has any indication of LBAs

Yes, it is SPARC.

May be the OS is too old / unpatched. Since a 2010 update, ZFS is able to adjust most of such cases.
Solaris 10 implemented around summer of 2012

I have been advised by my Technical Assistance Center to buy a drive that has the same Sun/Oracle part number rather than the actual drive manufacturer's part number, like I thought I had done. The iostat output tells me that they are different though. They claim that despite the manufacturer, Seagate, Haitachi, etc, if the Sun part numner is the same then it will have the same geometry. Does this sound right?

Hmmmm, no LBA value on the disk labels, that is unusual.

However, you can see from your prtvtoc's in post#1 that your new disk is smaller than the old one.

Partition 2 (which on Sun describes the whole disk) sector count says:
Code:
old 585912500
new 585865020

Some new filesystems will reserve some space (eg, 100MB) on the drives to manage such a situation but if your filesystem has used the full capacity then there's no alternative but to get one with the same, or more, sectors (LBA's).

The disks have actually the same size, reported as exactly 300000000000 bytes. The s2 partition (or slice) is not really the whole disk but the accessible part of it.

The difference is due to the way the disks firmware defines their geometry.

Two cylinders are reserved by Solaris on each disk and the fact the cylinder size differs make the available space slighty smaller on one of the disks.

If you are adventurous, you might try twiddling with the format command to try setting the disk type of the new disk to the same one as the older one.

When was created the pool ?
