我用zfs也只用mirror
主要是zpool和zfs的功能划分比btrfs更合理和明确

【 在 Dazzy 的大作中提到: 】
: 它关于btrfs的更新中有这么一条：
: - raid-stripe-tree
: New tree for logical file extent mapping where the physical mapping may not match on multiple devices. This is now used in zoned mode to implement RAID0/RAID1* profiles, but can be used in non-zoned mode as well. The support for RAID56 is in development and will eventually fix the problems with the current implementation. This is a backward incompatible feature and has to be enabled at mkfs time.
