BTRFS:raid1 有问题吗?

btrfs df / 报告此内容

btrfs filesystem df  /
Data, RAID1: total=4.26TiB, used=4.16TiB
System, RAID1: total=8.00MiB, used=752.00KiB

WARNING: Multiple block group profiles detected, see 'man btrfs(5)'.
WARNING:   Metadata: single, raid1
WARNING:   System: single, raid1

我需要重新平衡 fs 或者什么来清除警告消息?

答案1

找到了解决方案,我只需要重新平衡

btrfs balance start --bg -dconvert=raid1 -mconvert=raid1 /

现在看起来很好,警告消息消失了

btrfs filesystem df /
Data, RAID1: total=4.14TiB, used=4.07TiB
System, RAID1: total=32.00MiB, used=608.00KiB
Metadata, RAID1: total=6.00GiB, used=5.16GiB
GlobalReserve, single: total=512.00MiB, used=0.00B
