Subject: Questions about multi-device behavior
Date: Wed, 17 Jul 2013 23:24:22 +0200 [thread overview]
Message-ID: <1860433.azE0Vf7tMy@horus> (raw)
Hello!
I create a btrfs volume comprised of two partitions:
# mkfs.btrfs -m dup -d single /dev/sdd1 /dev/sde1
metadata ist mirrored on each device, data chunks are scattered more or less
randomly on one disk.
a) If one disk fails, is there any chance of data recovery?
b) If not, is there any advantage over a raid0 configuration.
Thanks and regards,
Florian
