Subject: btrfs raid1 metadata, single data
Date: Fri, 07 Aug 2015 10:49:58 +0200	[thread overview]
Message-ID: <55C47136.2080402@render-wahnsinn.de> (raw)

Hi, I was wondering.

What exactly is contained in btrfs metadata?

I've read about some users setting up their btrfs volumes as
data=single, but metadata=raid1

Is there any actual benefit to that? I mean, if you keep your data as
single, but have multiple copies of metadata, does that still allow you
to recover from data corruption? Or is metadata redundancy a benefit to
ensure that your btrfs volume remains mountable/readable?
