我这样做了:
/sbin/btrfs scrub start -B /mnt/ospool
ospool 是一个带有 3 个 sata 驱动器的池。
$ sudo btrfs filesystem show /mnt/ospool
Label: ospool uuid: ef62a9ec-887f-4a70-9c89-cf4ce29dfeb1
Total devices 3 FS bytes used 125.16GiB
devid 1 size 93.13GiB used 82.03GiB path /dev/sdc3
devid 2 size 97.66GiB used 86.03GiB path /dev/sdd3
devid 3 size 97.66GiB used 86.00GiB path /dev/sde3
我得到了这样的回应:

如何在具有 3 个磁盘的 BTRFS 上获得 3 个无法纠正的错误?
