In addition to this comes another aspect. What if one drive fails and you find bad data on another in the same VDEV while resilvering. This is quite common these days, and for mirrors, that will mean data loss unless you mirror 3-way or more, which will be rather costy.

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
