Failed to mount USB stick on router

Installing and Using OpenWrt
1

I'm a beginner user of OpenWRT and needed to mount my USB stick in order to store some logs on it. I run through the steps written on the following link:

But even if unplug the USB stick from the router, /mnt/sda1 is still there and I can still copy files to the folder. It seems I failed somewhere with mounting my USB stick, because /mnt/sda1 is located on the router instead of the USB drive. Can someone please help me with mounting my USB stick properly?

Try mounting and check:

/etc/init.d/fstab boot; sleep 3; grep -e /dev/sda /etc/mtab

I'm getting the following result:

root@OpenWrt:~# /etc/init.d/fstab boot; sleep 3; grep -e /dev/sda /etc/mtab
block: check_filesystem: /usr/sbin/e2fsck not found
block: No "mount.ext4" utility available
block: mounting /dev/sda1 (ext4) as /mnt/sda1 failed (2) - No such file or directory
root@OpenWrt:~#

Do I need to run any commands before?
If I need to retry mounting, could you please paste the correct command so that I won't fail?

You appear to be missing packages to get it to work.

Is e2fsprogs installed?
