I'm trying to mount an ext3 drive (sd or usb) to create more space for installed programs. On the older versions of the firmware, this wouldn't be a problem. All I'd need to do is format the drive or card as ext3 and then follow the instructions on the luci interface. However, I can't mount drives anymore:
- Code: Select all
root@OpenWrt:~# mount /dev/sda1 /tmp/extroot
mount: mounting /dev/sda1 on /tmp/extroot failed: Invalid argument
I tried running
- Code: Select all
/proc/filesystems
- Code: Select all
-ash: /proc/filesystems: Permission denied
error.
How can I mount the filesystem on drives again?
***EDIT***
I tried using a different filesystem (fat32) but I get this error now:
- Code: Select all
root@OpenWrt:~# tar -C /tmp/introot -cvf - . | tar -C /tmp/extroot -xf -
./
./bin/
tar: can't create symlink './bin/ash' to 'busybox': Operation not permitted
./bin/ash
It seems like the root user doesn't actually have root privileges in openwrt. Whats going on?
