2. mogilefs重要特性
Re-Replicating Files
If a drive dies, mogilefs will attempt to avoid the device, but it will not automatically re-replicate files which were on the device. You must manually mark it as 'dead' via mogadm. As soon as you do so, mogilefs will start to remove files that were on the device and attempt to re-replicate them.
