I cannot but agree. iostat will show better info, and a script like http://karlsbakk.net/iostat-overview.sh can give you a pretty decent overview of which drives should be replaced. This will show you drives with errors reported. In my experience, a drive can last a long time, but may die early as well.

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
