  1. 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 str
  2. 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 w
  3. 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?
  4. 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 I recently realised that the os it is running on is outdated (Debian Stretch with Armbian Linux 4.14.150-odroidxu4).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?
  5. 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 imple
  6. 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.
  7. 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
  8. 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
  9. ...installed the JMS Firmware upgrade to be on the safe side and it seems I did not have the current version.

  10. Hi all! I am running a nextcloud server on an odroid HC2 and a 4 TB WD red HDD. So far, so good (thanks again @Igor for the quick help with the kernel downgrade!). And since I have bought the sbc recently, I do not seem to have the older firmware version with the HDD "emergency power down" bug, i.e. I haven't heard clacking sound from the HC2. Today, I set HDD spindown to 1 hour via hdparm (wd red does not support apm) because the HDD would spin down after about three minutes on its own. The HDD does not seem to apply these settings, so I installed smartmontools to check the HDD in
  11. didn't change cables... downgrading the kernel did the trick! Thanks!
  12. oh, thanks! That was quick! which cables? the ethernet cable? So, it is rather unlikely the fstab entry with the 4tb hdd? I thought maybe the hdd is "too big" and checking the filesystem causes problems... EDIT: And how do I fix the network/downgrade the kernel? The migration is not finished yet, so downloading new image etc. wouldn't be a big problem. Should I do just that?
  13. Hi! recently bought a HC2 from hardkernel to migrate my nextcloud from a raspberry pi 3b. HDD is a WD red 4 TB. armbian stretch with the 4.19 kernel, downloaded from armbian.com (Armbian_5.69_Odroidxu4_Debian_stretch_next_4.19.14). My problem: after boot (sudo reboot now or sudo shutdown -r), no possibility to login, i.e. angryip scanner doesn't show the hc2, putty times out when trying to connect. All LEDs are lit or pulsate respectively. I have to physically disconnect the power supply and reboot, then I can easily login. This is probably not very healthy for the hdd
