Hello my friends. I have a TP-LINK TD-W8970 with 8 MB of Flash memory.
I was going to install openvpn on my openwrt using following commands:
opkg update opkg install openvpn-openssl
Suddenly it show the 'No space left on device' message. so, I check the available space on the device, and here is the result (df command):
Filesystem 1K-blocks Used Available Use% Mounted on /dev/root 3584 3584 0 100% /rom tmpfs 29096 384 28712 1% /tmp /dev/mtdblock4 2496 2416 80 97% /overlay overlayfs:/overlay 2496 2416 80 97% / tmpfs 512 0 512 0% /dev
I reboot the device, but the memory still full. although the installation of package unfinished, so I have nothing to remove to free up my space.
now every time I login via SSH, this alert appears:
Your JFFS2-partition seems full and overlayfs is mounted read-only. Please try to remove files from /overlay/upper/... and reboot!
So please help me about this things:
- How to remove unfinished package ( opkg install openvpn-openssl) to free up the space?
- Is there a solution to increase the available space? like using USB Flash drive as secondary partition for installing packages on it.
