Subject: Data integrity and RAID
Date: Thu, 4 Dec 2008 11:47:07 -0800 (PST) [thread overview]
Message-ID: <20841008.post@talk.nabble.com> (raw)
I'm looking for a software solution to help replace my existing raid hardware
setup. The hardware mimics RAID-1 (in that it has 3 mirrors), except for the
fact that on read all 3 mirrors are compared and possibly error corrected
before data is returned. I don't neccessarily need a RAID-1 solution, it
just seems closer to what I already have and also that it also can recover
from 2 simulateous disk failures.
So far I've played with a software RAID-1 array of USB flash drives. My
issue is that software RAID-1 does not check for or recover from data
corruption unless a read or write to disk actually fails. Integrity is a
major concern for me, I need to know that all data going to and from disk is
correct at all times.
All advice and comments are welcomed.
