Content-Type: text/plain; charset=ISO-8859-1 Sender: linux-btrfs-owner@vger.kernel.org List-ID: Hi, Can anybody comment on how BtrFs (particularly RAID1 mirroring) interacts with drives that offer error recovery control (or TLER in WDC terms)? I generally prefer to buy this type of drive for any serious data storage purposes I notice ZFS gets a mention in the Wikipedia article about the topic: http://en.wikipedia.org/wiki/Error_recovery_control Should BtrFs be mentioned there too? Regards, Daniel
