I've been running RAIDz3 for a backup machine (zfs receive from the main box), and the write performance was rather low. I'd rather use lvm or raid-something over different raid-6 volumes. Spread out the risk factor. With ~8 drives in each raid-6 set, the risk is low enough to allow for rather large volumes. -- Vennlige hilsener / Best regards roy -- Roy Sigurd Karlsbakk (+47) 98013356 roy@xxxxxxxxxxxxx http://blogg.karlsbakk.net/ GPG Public key: http://karlsbakk.net/roysigurdkarlsbakk.pubkey.txt -- I all pedagogikk er det essensielt at pensum presenteres intelligibelt.
