How can i mount /dev/sdb4 for torrent downloading in my openwrt?

[frollic]

mount /dev/sdb4 /mnt

you might need additional packages, for file system support, etc.

[luofeiyu]

root@OpenWrt:~# mount  /dev/sdb4   /mnt
mount: mounting /dev/sdb4 on /mnt failed: Invalid argument

/dev/sdb4 is recognized in debian, there is no /dev/sdb4 in openwrt!
Which additional package need install then?

[frollic]

start with block-mount, and perhaps blockd.

might want to install fdisk or gdisk to verify the disk partition is readable.

[luofeiyu]

Solved.

opkg update
opkg install block-mount fdisk
