I was expecting to see a lot of small transactions, indicating seeking across the file system, but the numbers seem normal enough. Is the drive & ZFS topology "normal" - you don't perhaps have a zpool made of multiple partitions/slices on the same drive? Can you send the output of "zpool status"? --------------enigBD918D4DC8EFD56E985CC50E Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFHsYPYldnAQVacBcgRAnKtAKDtSkOaqoR83qvFG+PS+wACieWaYwCePM5O 7rhDYnrPkTXNgdQ8pDZCd+U= =2NGl -----END PGP SIGNATURE----- --------------enigBD918D4DC8EFD56E985CC50E--
