So, i set up an OrangePi PC with armbian just to run pihole+unbound about 4 or 5 months ago. Out of curiosity i ran cat /sys/fs/ext4/mmcblk0p1/lifetime_write_kbytes 31366225 That's 31GB written on the 8GB sd card which is almost empty df -h Filesystem Size Used Avail Use% Mounted on udev 430M 0 430M 0% /dev tmpfs 100M 11M 90M 11% /run /dev/mmcblk0p1 7,2G 1,7G 5,4G 24% / tmpfs 500M 3,5M 497M 1% /dev/shm tmpfs 5,0M 4,0K 5,0M 1% /run/lock tmpfs 500M 0 500M 0% /sys/fs/cgroup tmpfs 500M 8,0K 500M 1% /tmp /dev/zram1 59M 8,4M 46M 16% /var/log tmpfs 100M 0 100M 0% /run/user/999 tmpfs 100M 0 100M 0% /run/user/0 Checking the data written since the last reboot 91 days ago awk '/mmc/ {print $3"\t"$10 / 2 / 1024}' /proc/diskstats mmcblk0 11032.2 mmcblk0p1 11032.2 11GB in 91 days. I checked the logs. Nothing out of the ordinary. The biggest files are the pihole logs (around 5MB per log which rotates daily) iotop -a shows that journaling writes about 1MB of data per hour to the disk.. that's still only 2GB per 91 days Is there a good way to see what exactly is writing so much to the SD card? Thanks in advance.

Thanks a bunch.

I remember that the maximum frequency was 1296Mhz back with Xenial, with kernel 3.x. It even says here Heat is not a problem since i have a large heatsink and temperature controlled fan, i was just curious about why the max frequency was bumped to 1368Mhz on the newer builds. What's the rationale behind it?

Bah, forget my previous port. I thought pin PA7 was pin 29 (which is, physically), but it's actually pin 7. Everything works fine.

Greetings, I'm not good with linux so excuse any stupidity i might say. I have been using Xenial for years now and just decided to update. In the past i was using the sunxi module to access gpio's For ex: echo 1 > /sys/class/gpio_sw/PA7/data Now in Bionic i just noticed gpio's are not accessed in the same way. According to this user, we can either use sysFS (which seems deprecated) or libgpiod. The problem is that i can't make it work. libgpiod: root@orangepi:~# gpioset gpiochip0 29=1 gpioset: error setting the GPIO line values: Unknown error 517 sysFS: root@orangepi:~# echo "29"

wrong? It's a clean install of Bionic server. I would prefer to use libgpiod since it looks less complex Can anyone point me in the right direction? Thanks a a lot.

I remember trying to install a usb wifi dongle in the past and while it gave me lots of headaches, i did manage to make it work. It's been a while since i used wifi (it's been a while since i used the SBC too to be honest). Today i decided to power it up at least just to update it. When it was installing kernel related stuff, it gave an error stating it couldn't build the 8192cu module (or something like that), the specific log says scripts/Makefile.build:432: recipe for target '/var/lib/dkms/8192cu/1.10/build/8192cu.o' failed make[1]: *** [/var/lib/dkms/8192cu/1.10/build/8192cu.o] Error 1 Makefile:1368: recipe for target '_module_/var/lib/dkms/8192cu/1.10/build' failed make: *** [_module_/var/lib/dkms/8192cu/1.10/build] Error 2 make: Leaving directory '/usr/src/linux-headers-3.4.113-sun8i' Among a long list of errors. Anyway, i tried using the usb dongle. While it seems to work at first, it has a strange behavior. First of all, now instead of only showing only a wlan1 interface, it also shows a wlxxxxxxxxxxxx one. Sometimes it auto connects to my wifi network on one, sometimes it connects with the other. Another strange thing: When it connects, it gets an ip and i can confirm in my router stats page that it's connected but as soon as i disconnect the lan cable, it looses connection with the router. I have tried most of the things i tried last time i made it work like compiling the rtl8192cu-fixes sources and installing them. I have 8192cu active in modules.conf, lsmod says that 8188eu is also active. I'm a newbie in linux and i already lost 3 hours trying to fix this. What am i missing? is the wlxxxxxxxxxxx supposed to show up? I guess you have all the info you need in the armbianmonitor file, if not, ask away. Thanks in advance. Damn, just noticed i probably posted this in the wrong section [EDIT: Pressed "send" by mistake while still writting)

Thank you for your reply. Indeed, removing that line solved the problem. What's weird is that i never changed my network configuration. What i did was: Install armbian -> disable gpu/hdmi -> update packages -> install webmin -> went to the network pane on webmin and got that error -> did other things I didn't check the network config before installing webmin so i don't know if it was already like that or it was indeed webmin that changed it. I never had that problem in the past so i'm guessing webmin had nothing to do with it or it's something from recent versions. Anyway, thanks a lot.

Greetings, I recently changed from an old loboris ubuntu distribution to armbian for my opi PC. I never had problems with it, it was just not getting updates for a long time since it's old and not a LTS. I never had problems with openvpn also.. installing from apt and creating ca's and users was a breeze. Now with armbian i simply cannot get it to work, i tried both with apt and compiling the latest version from source. I cannot get it to start. Doing systemctl start openvpn Job for openvpn.service failed because the control process exited with error code. See "systemctl status openvpn.service" and "journalctl -xe" for details. journalctl -xe -- Unit openvpn.service has begun starting up.

I also tried PiVPN, it fails in the middle of the installation with the error : : error fetching interface information: Device not found : error fetching interface information: Device not found Going to Network Configuration on webmin also gives an error: ifconfig works fine and gives me both eth0 and lo I tried several things i've read on some tutorials but none worked.. again, i never had these problems with the old distro so i'm guessing its armbian related.. anyone has a clue on what might be? Thanks in advance.

I was about to open a new thread makig the same question as OP but for the OPI PC. It was nice to find this first. Fortunately the OPI PC is similar to the One. http://i.imgur.com/Tyrbb5g.jpg I have no idea why technik007_cz and Tido were acting like that. It's very handy to be able to hardware reset the board. I have a raspi running headless 24/7 and an arduino connected to it, pinging it periodically through the GPIO. If for some reason the raspi freezes and stops responding for a while, the arduino resets it. I intend to do the same with the OPI PC.
