  1. Hi everyone! For about a week now, I have been using armbian 22.11.1 on my new Odroid HC4, which is my Nextcloud server. As alway, armbian is rock solid 😉 I have just a little question: Can one modify the information presented in htop? I'd like to have "CPU temperature" and "TX today" (meaning sent bytes) showing. The welcome screen already shows "CPU temperature" and "RX today". I know that the CPU temperature can be read here /etc/armbianmonitor/datasources/soctemp and but I can't find it in the htop-configuration under "available meters".
  2. I received my new Odroid HC4 today and ran into the same problem. I used the recent armbian, but I booted into petitboot (with an attached display and keyboard), and erased the flash storage from there. This worked just fine! As far as I can tell, this has no downside when compared disabling petitboot via ssh, other than having to have a display and a keyboard. @Igor: Thank you for providing armbian!!!
  3. ... I've recently found this: https://github.com/ThomasKaiser/sbc-bench/blob/master/Results.md ...using sbc-bench might be the better way to compare boards for my needs (server).
  4. Hi! THANKS for your answer! unfortunately, searching via apt search sysbench doesn't return results. My sources seems somewhat outdated, since I run armbian 22.02 but the sources are referring to buster? How do I change them? fridtjof@odroidhc2:~$ cat /etc/apt/sources.list deb http://deb.debian.org/debian buster main contrib non-free #deb-src http://deb.debian.org/debian buster main contrib non-free deb http://deb.debian.org/debian buster-updates main contrib non-free #deb-src http://deb.debian.org/debian buster-updates main contrib non-free deb http://deb.debian.org/debian buster-backports main contrib non-free #deb-src http://deb.debian.org/debian buster-backports main contrib non-free deb http://security.debian.org/ buster/updates main contrib non-free #deb-src http://security.debian.org/ buster/updates main contrib non-free
  5. Hi! my Odroid HC2 is running for more than three years now (24/7), hosting a nextcloud instance. Other than two preemptive SD-card swaps no maintenance necessary, armbian performs really great 🙂 Since I was thinking about upgrading to a better machine (Nano Pi M4, if they ever sell them again...) I wanted to install sysbench to compare some CPU specs. But sudo apt-get install sysbench gives: unable to locate package sysbench I'm running a recently upgraded armbian, v22.02.1 with Kernel 5.4.181. Any ideas? I'm pretty sure I had sysbench on an earlier version of armbian. EDIT: fixed typos
  6. Hi! my odroid HC2 is running pretty great on armbian 5.90 for >1,5 years (24/7) now. Running a nextcloud instance, with decent perfomance, even when clocked to 600/1200 Mhz in the summer, because of one (1) crash, that I think might have been heat-related. The thing I'm wondering about: in htop, it shows only ( .LITTLE) cores for eight lines, but the cpu is a (.big.LITTLE) architecture and my other HC2 sbc, which runs armbian 20.02.7, show "(.big.LITTLE)" in htop. Perfomance in sysbench is equal on both boards, so this might mean nothing, but it still seemed strange to me. Anyone knows why htop only shows "( .LITTLE)" cores?
  7. ahh okay. The reason I even realized that my HC2 is not running the most recent armbian is that I have another one, which I set up some months later and this other one shows the CPU cores differently in htop: "(.big.LITTLE)", whereas the HC2 running the nextcloud only shows 8 lines of "( .LITTLE)", as if there were no .big cores. When comparing those two machines, which I thought were running on the same OS, I found out that in the months between setting up these two machines, there must have been the armbian OS update. So, I guess I'll stay with stretch (and try to figure out why there are only .LITTLE cores showing). Thanks!
  8. Thanks! I think the kernel stays the same in the new image, but since debian is upgraded, I should start from a fresh image? But is there actually a downside by staying on stretch? Security-wise I guess the answer is: always stay up-to-date, right?
  9. Hi! I've been running two sbc (Odroid HC2) for about 1,5 years. I recently realised that the os it is running on is outdated (Debian Stretch with Armbian Linux 4.14.150-odroidxu4). There is a nextcloud instance running on it and I really (!) like the stability of my setup. So far, I've had one (1) crash in 1,5 years on a system that is running 24/7, maybe heat related in the hot summer. Reboot automatically once a week, nightly off-site backup, login via ssh-keys. So my question is...: Shall I update and if yes shall I do this from a fresh install or is there a built-in way? Thanks!
  10. Hi! my nextcloud instance on an odroid hc2 running armbian has been running stable and smoothly for several months now. Thanks Igor and the whole armbian team! I have one question though: Task: I convert videos with ffmpeg to reduce file size and optimize them for streaming observed behaviour: the CPU is getting very hot! In the evening up to 100 °C (see below), but at noon I have seen temperatures of up to 115 °C! I read somewhere that 110 °C is the critical temperature for the board and the stock hardkernel image has an emergency shutdown implemented. But my board running armbian seems to be negligent of this. On a side note, the CPU frequency reported in armbianmonitor -m is 1800/1300, in htop all 8 cores show 1300 ( .LITTLE)? expected behaviour: shouldn't the CPU be throttled automatically? excerpts from armbianmonitor -m: Stop monitoring using [ctrl]-[c] Time big.LITTLE load %cpu %sys %usr %nice %io %irq CPU C.St. 17:56:51: 1800/1300MHz 2.20 2% 0% 0% 1% 0% 0% 84.0°C 2/13 17:56:57: 1800/1300MHz 2.99 93% 0% 17% 75% 0% 0% 87.0°C 2/13 17:57:02: 1800/1300MHz 3.79 93% 0% 18% 74% 0% 0% 89.0°C 2/13 17:57:07: 1800/1300MHz 3.89 82% 0% 13% 68% 0% 0% 84.0°C 2/13 17:57:12: 1800/1300MHz 3.74 80% 0% 18% 60% 0% 0% 85.0°C 2/13 ... 17:59:19: 1800/1300MHz 9.83 90% 0% 16% 73% 0% 0% 98.0°C 2/13 17:59:25: 1800/1300MHz 10.38 95% 0% 15% 79% 0% 0% 99.0°C 2/13 Time big.LITTLE load %cpu %sys %usr %nice %io %irq CPU C.St. 17:59:30: 1800/1300MHz 10.27 94% 1% 22% 70% 0% 0% 100.0°C 2/13 17:59:36: 1800/1300MHz 9.85 90% 0% 16% 72% 0% 0% 99.0°C 2/13 17:59:42: 1800/1300MHz 10.10 95% 0% 17% 77% 0% 0% 100.0°C 2/13 17:59:48: 1800/1300MHz 10.33 98% 0% 18% 79% 0% 0% 102.0°C 2/13 17:59:54: 1800/1300MHz 10.38 95% 0% 22% 71% 0% 0% 101.0°C 2/13 18:00:00: 1800/1300MHz 10.79 97% 1% 20% 75% 0% 0% 100.0°C 2/13
  11. Figured it out, using pishrink, finally! It takes a while because 28 GB of empty space are being copied in the beginning, but anyhow ;-) This is my procedure: 1) boot from "plain" armbian (#2, see above) 2) insert original SD card (#1, 32 GB) in reader 3) dd if=/dev/sd#1 of=/path/to/image.img 4) pishrink.sh /path/to/image.img 5)dd if=/path/to/image.img of=/dev/sd#3, #3 being the backup SD card, 16 GB note: "#1", e.g. is "/dev/sda", not "/dev/sda1", since you need to do a block level copy of the device, not only the disk.
  12. Update: I tried to clone the SD card doing the following, inspiration from this thread: 1) download armbian image, burn to another SD card (#2) 2) run armbian from this SD card #2 (works) 3) insert former boot SD card (#1) and backup SD card (#3) in SD card reader 4) dd if=/dev/#1 of=/dev/#3 bs=1M count=4 (to copy partition scheme and bootloader) 5) mount #1 /mnt/origin, mount #3 /mnt/clone 6) rsync -avSz /mnt/origin /mnt/clone (seems to work) 7) check /etc/fstab on #3, adjust UUID of / 8) try to boot from #3 --> doesn't work :-( I don't want to (can't) use dd because the SD card #3 is only 16 GB, whereas the #1 SD card is 32 GB, and my armbian installation takes only 4,1 GB. And I understand Igor's opinion that it's much more useful to save /home/* and /etc/* and a list of installed packages, but I want to have a working clone handy for instant use in case the #1 SD card fails, mostly because I am planning on installing pihole and I am worried about increased wear on the SD card. Can someone tell me why the approach aboce doesn't work? Does it have to do with /etc/fstab? Partitions? Thanks in advance! EDIT: both #1 and #3 are high quality (SanDisk Ultra A1)
  13. Hi! short question: Best way to create a bootable clone of sd card? I did some reading and found ">>create image on windows >> shrink image via gparted" doesn't work for me since I dont have a second computer running linux (will the linux subsystem on windows 10 help?). In the past, I used the rpi-clone on a raspberry, but reading in this forum has taught me that hotcloning an armbian sd card via script is not necessarily safe. Computers availabel to me are: 1) odroid hc2 running armbian 2) acer laptop running windows 10
  14. ...installed the JMS Firmware upgrade to be on the safe side and it seems I did not have the current version. See output of smartctl -a /dev/sdb1 below: === START OF INFORMATION SECTION === Vendor: JMicron Product: Generic Revision: 3101 Compliance: SPC-4 User Capacity: 4,000,787,030,016 bytes [4.00 TB] Logical block size: 512 bytes Physical block size: 4096 bytes LU is fully provisioned Logical Unit id: 0x3001234567891234 Serial number: 0123456789ABCDEF Device type: disk Local Time is: Tue Jan 29 11:45:38 2019 UTC SMART support is: Unavailable - device lacks SMART capability. Serial Number has changed, still no luck getting through to the HDD... EDIT: solved it! smartctl -a /dev/sdb1 gives the result pf the JMicron bridge, smartctl -a /dev/sdb1 -d sat gives the results of the HDD.
