WE NEED !YOUR! HELP

Recommended Posts

Hi,

 

Thank you for your interest, you won't be disappointed. You have probably read that the developer want to do some changes - and some of this changes are now ready to get tested in the BETA's of armbian.

 

Do not test with your 'production' SDcard unless you have done a backup ;-)

 

Once done that, please go to 'armbian-config' System  switch to BETA (Nightly), do an update/upgrade, reboot, check if your system still performs as before.

  • If it does work like before - please let us know and post your 'armbianmonitor -u' link
  • If it doesn't work, please try a reboot, check if the problem is reproduceable and if so  explain the steps to reproduce it and post your 'armbianmonitor -u' link

 

If you like to know what has changed or is changing:

Kernel upgrade for Allwinner boards. NEXT is 4.17.y and it's getting daily updates. (LIB_TAG="sunxi-4.18" in our build system)

https://forum.armbian.com/topic/7398-bsp-scripts-rfc/

https://forum.armbian.com/topic/5565-zram-vs-swap/

https://forum.armbian.com/topic/6444-varlog-file-fills-up-to-100-using-pihole/

 

This is not all, see details on GitHub look at the shell code - which makes this happen - more eyes less errors :thumbup:

 

And if you want to try a fresh install, look for the nightly created 17. June https://dl.armbian.com/

 

Thank you in advance for your support

Hi, I just ran some tests with fresh install on my tinker board

The keyboard-setting seem to stick now and I have installed via armbian-config Transmission and the minimal desktop. After that the Memory footprint in htop went from 70MB to 186MB. File Manager Thunar starts in this release much quicker than with Xenial. The display resolution still perfect on 4.14.

Well done :)

Not sure what I'm looking for, I've not even noticed any difference. I'm sure there is, but I can't see it. And this is a good thing!

 

I originally did it on my Orange Pi Zero & didn't notice ANYTHING different so did it on my PC and couldn't notice it there either!

 

Update: OK I've found the change to zram on the PC but not the Zero, even after an update!

 

Orange Pi Zero -> http://ix.io/1dIO [Updated] http://ix.io/1dJ3

Orange Pi PC -> http://ix.io/1dIA

 

/me has no idea what to look for.

 

I hope this helps though!

This bug will hopefully be fixed with today update ... which I am still fixing for other problems. It would be best to try with not updated image yet or some older image updated to nightly.


Thank you for your help! 

 

Edit: Please pay attention to log rotation service. If that works properly. Starting with today update, current is broken.

Shall I stress more the update path to test?

Shall I add in the first post to do: sudo apt update && upgrade for fresh-install to get your latest bugfix?

I just ran an update on :  Armbian_5.38_Tinkerboard_Ubuntu_xenial_next_4.14.xx_desktop.img   'armbian-config' System  switch to Nightly (BETA).

 

My keyboard was now and then in USA-mode instead of Switzerland, so I have started armbian-config. I think this armbian-config (after the upgrade) is different to my fresh install of last night.

It starts now faster just like the fresh install (by the way)  I went to PERSONAL, LOCALES, de_CH.UTF-8  &  en_US.UTF-8, wanted to stay on english (it is easier to copy text to the forum) BUT change to my keyboard - the keyboard change option  did not show up. While I am sure it did on the fresh install - or am I wrong.. it was late.

Today's update will include more fixes ... but even with it, some leftovers shell be manually cleaned from the previous update. I didn't make a script for that.

 

To do minor, manual clean up:

sudo nano /etc/logrotate.conf

sudo nano /etc/logrotate.d/*

 

Removing those lines:

 

# compress

su root syslog

just ran  sudo apt update && upgrade   and an update for armbian-config  came through

 

UPDATE:  in the new armbian-config the keyboard is available.

Maybe a stupid question, why didn't it come when I switched to Nightly ?

Wouldn't it be enough to 'comment' these lines, well #compress already is - like this ?

I have done the same checks for zram like yesterday. It is one dev less and lzo versus lz4.

That's ok. A package is not present in Debian.

 

Next thing to test is ... logrotate. It check's every 15 minutes if we are over 75%. Then it save logs, rotate them and truncate/zero logs on the /var/log ... this is theory and I hope reality as well. We need to test random, common and extreme situations of logging to see if default settings are O.K. for most cases. Then somewhere must be written how to configure this system.

ZRAM service timeouts

Can you be more specific, how you found that bug?
What can be done to analyse this behavior ?
Is it on both upgrade and fresh install ?

Are the Google results any helpful or is it armbian specific ?

I was testing freshly made Odroid C2 DEV build with Bionic ... I haven't narrowed down the problem. It can be a kernel or some other service related. ATM I don't know if it's our or general problem.

Yes, it succeeds, but why, for what is waiting? Dependency issues?

I did boot Armbian_5.48.180624_Odroidc2_Ubuntu_bionic_dev_4.17.2 today...

I do get a heartbeat at the blue LED, but no sign of life at the ethernet port (green is going up and down, but orange never comes on) ....and I wonder even with a USB-Ethernet device there is no DHCP request.

At this time I didnt got a serial port attached :(

@Igor today I got the same effect (no usb-ethernet) at the OPi Zero Plus2 H5 with 

Armbian_5.48.180624_Orangepizeroplus2-h5_Ubuntu_bionic_dev_4.17.2

 

On my User-Build Kernel (with LED-Support and HDMI-disable for proper reboot) the USB-Ethernet does work.

 

But at the nightly I do get the following error-messages (for orientation some good messages before the errors) via the serial port:

Maybe these are the "same" as on the Odroid C2, because there is also no onboard/USB-Ethernet.
Here as hidden the serial Boot-Log from the first boot (my normal user-build system/kernel is on emmc and this is the sdcard boot):

the USB-Ethernet does work.


As expected. 4.17.y don't have overlay support there ... and USB ports are disabled by default on this board. DEV is experimental/preparation build and many things might be broken.

Maybe these are the "same" as on the Odroid C2

 

Unfortunately no. USB on C2 is much more problematic. It's enabled but sometimes doesn't work. Here at least we know why it doesn't :)

 

We seek ZRAM related issues at this point. That is planned to go into stable builds - when it's working as expected or at least if we know what prevents that, while 4.17-18 is months away.

Ahh - I didnt know that overlay support is disabled - that do clarify some things ;)

I know DEV is a experimental/preparation build, but on the most SBCs here it do work quite well! :)
Now I know that mostly more the onboard/original hardware should work.

Our target for Allwinner is to get 4.18.y operational and 4.17.y servers only to prepare patches, as a temporal version.

Can someone answer a naive question about the new zram implementation? I think I've found something important that's been overlooked. 

 

# Use half of the real memory by default --> 1/${ram_divisor}
	ram_divisor=2
	mem_info=$(LC_ALL=C free -w 2>/dev/null | grep "^Mem" || LC_ALL=C free | grep "^Mem")
	memory_total=$(awk '{printf("%d",$2*1024)}' <<<${mem_info})
	mem_per_zram_device=$(( ${memory_total} / ${zram_devices} / ${ram_divisor} ))

	for (( i=1; i<=zram_devices; i++ )); do
		[[ -f /sys/block/zram${i}/comp_algorithm ]] && echo lz4 >/sys/block/zram${i}/comp_algorithm 2>/dev/null
		echo -n ${mem_per_zram_device} > /sys/block/zram${i}/disksize
		mkswap /dev/zram${i}
		swapon -p 5 /dev/zram${i}
	done
	echo -e "\n### Activated ${zram_devices} zram swap devices with ${mem_per_zram_device} MB each\n" >>${Log}

 

Is the intent here to devote half of real memory to zram and take advantage of compression to multiply that chunk of memory, or is the intent to provide some small swap space without hitting swap on flash storage?

 

Right now the script is doing the latter, not the former. The current implementation makes swap space equal in size to half of ram, which is then compressed (usually at 2:1 or 3:1, most often at 3:1) and stored in memory. This means that, on average, the amount of actual ram used by zram hovers between 25% and ~17% rather than the apparently intended 50%.

 

I spent quite a bit of time researching and profiling something similar for my own use and I've settled on the following to allocate 50% of real memory to zram:

 

    mem_per_zram_device=$(( 3 * ${memory_total} / ${zram_devices} / ${ram_divisor} ))

 

Coincidentally this is the same zram allocation that Google makes on ChromeOS.

 

I've seen the same mistake made in almost every single zram script that I can find via Google so this definitely isn't an Armbian thing. It looks like someone made the original logic error at some point a long time ago and it's been copy-pasted into every zram setup script for the last 7 or 8 years.

 

For what it's worth setting /sys/block/zramN/mem_limit does what everyone seems to be expecting and limits the amount of ram that the zram device can use. Unfortunately there is no way to adaptively vary /sys/block/zramN/disksize according to the actual compression ratio so the currently accepted best practice seems to be assuming 3:1 and punting (this is what Google does on ChromeOS.)

Hi, I just installed the 5.49 nightly build (4.17.3) on my OrangePI Prime.

It's running quite well and I had almost no issues until now, except for:

. some errors reported by journald (journal corruption) that ended up filling up all /var/log space.  

. sometimes the reboot doesn't work, freezing on a black screen with a cursor blinking in one corner.

The errors reported by journald were probably caused by my need to power off and on to resume after the reboot freezing.

I had to delete the log files though to be able to perform the system settings (language, timezone and so on).

Not sure. I also noticed this (only?) on Bionic version which has some other problems and it's still in testing/fixing phase.

 

Thank you for the report. Next time supply logs with:

armbianmonitor -u

This way we can see more.
