mhddfs 没有按预期工作

当我跑步时df -h我得到：

/dev/sdc1                        1.9T   71M  1.9T   1% /mount2
/dev/sde1                        466G   26M  466G   1% /mount3
/dev/sdd                         466G   16M  466G   1% /mount4
/mount1;/mount2;/mount3;/mount4  4.6T  183M  4.6T   1% /NAS

但正如您所见，这应该是这样/NAS的！4.6T1.9T + 1.9T + 466G + 466G = ~ 5T

因此我将硬盘像这样安装在上面/etc/fstab：

/dev/sdb1 /mount1       exfat defaults 0 0
/dev/sdc1 /mount2       exfat defaults 0 0
/dev/sde1 /mount3       exfat defaults 0 0
/dev/sdd  /mount4       exfat defaults 0 0

然后/etc/rc.local我运行以下命令：

sudo mhddfs /mount1,/mount2,/mount3,/mount4 /NAS -o allow_other

出了什么问题？

sudo fdisk -l

/dev/sde1 和 /dev/sdd

答案1

（1.9T + 466G）*2 = （1.9T + （466/1024）T）*2 = 4.7T

错误 (<=3%) 对我来说似乎没问题。
