That's for dedup, 150 bytes per block, meaning approx 1GB per 1TB if all (or most) are 128kB blocks, and way more memory (or L2ARC) if you have small files.

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
