Subject: Use RAID-6!
Date: Tue, 16 Apr 2013 18:44:31 +0200 (CEST) [thread overview]
Message-ID: <15345091.8.1366130671716.JavaMail.root@zimbra> (raw)
Hi all
After reading this list for some time, there's a single mode of failure that's repeated over and over: RAID-5 loses a drive and finds bad data on another (or just loses another). This is rather normal, far more than documented by the disk vendors. This is also the case with "professional" systems with "enterprise" drives.
So, if you can afford another drive, please use RAID-6. Do *not* trust RAID-5 with something like 8 drives.
Also, maybe this should be on an FAQ/RAID tutorial somewhere?
Vennlige hilsener / Best regards
roy

I all pedagogikk er det essensielt at pensum presenteres intelligibelt. Det er et elementært imperativ for alle pedagoger å unngå eksessiv anvendelse av idiomer med xenotyp etymologi. I de fleste tilfeller eksisterer adekvate og relevante synonymer på norsk.
