I saw in LuCI that rrd statistics not got updated. So I begin troubleshooting...
I login to router and see
Your JFFS2-partition seems full and overlayfs is mounted read-only. Please try to remove files from /overlay/upper/... and reboot!
df Filesystem 1K-blocks Used Available Use% Mounted on /dev/root 2816 2816 0 100% /rom tmpfs 62256 1892 60364 3% /tmp /dev/mtdblock9 11008 10836 172 98% /overlay overlayfs:/overlay 11008 10836 172 98% / tmpfs 512 0 512 0% /dev
I see that my log file 50 MB on an external USB stick
du -sh * | sort -h 54.0K rrd 49.2M logs
I delete the log files and reboot
Then the login message is gone.
But the files I deleted was on an external USB disk attached to router. It should not matter how big this is?
My rrd stats also on USB stick / external
Can you explain me? What did I do wrong?
