Just a hunch, but try to run iostat -e or -E to see the error statistics. http://karlsbakk.net/iostat-overview.sh will give you a nice overview if you're on a wide terminal. The times I've seen one drive slow down a pool, it has always been because of errors on that drive.

Det er et elementært imperativ for alle pedagoger å unngå eksessiv anvendelse av idiomer med fremmed opprinnelse. I de fleste tilfeller eksisterer adekvate og relevante synonymer på norsk. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
