  1. Ok, was about to write it's also not visible for me on 4.9. Alright, so I stay at 4.9. and wait until I get 4.14 with apt upgrade. Good thing we always get spoiled by you guys with optimized configurations for everything by default, also when installing OMV via armbian-config
  2. Great news, I think I'm also on an older kernel, 4.9. I guess. I thought of manually switching to a newer kernel. But I'm confused with debian version. Op says he runs debian stretch, but if I look to the download page I only read armbian xenial or armbian jessie. I'm unsure which debian version I run...can't look it up atm.. Also on Dl page I read this, which I may have missed upon earlier install or it is just new: This board is stripped Odroid XU4 and we use the same images, however, we provide a specially optimized config which has to be applied manually. This results in shorter boot time and lower consumption. Run armbian-config utility and go to section system -> DTB and select optimized board configuration for Odroid HC1. The same config is valid for HC2 and MC1. @jogger Just in case you also didn't know there's an optimised config for our boards.
  3. A recent check of failed services showed me that following service failed: systemd-update-utmp-runlevel.service Checking via journalctl I see this: Failed to write utmp record: No space left on device So far I understood it has to do with the space for the logs being full, I can delete logs to make place. My question is, how could I have that done by default in an easy way? The message itself doesn't bother my that much but I guess there are no new logs created if there's no space which isn't ideal.

    [Odroid HC2] Bad file transfer speed after omv update?

    Got rid of the syn flooding and also reapplied thermal paste. I saw that hardkernel (or better said the factory where the boards are produced) did a good job on the paste. I noticed temp really spikes up when I tranfer sth. via network, from like 55 to over 70 degree. Is that to worry? I don't copy sth. at full speed all the time. I only notice it via smb, via nfs there isn't suach a spike in temp.

    [Odroid HC2] Bad file transfer speed after omv update?

    Hmm... now transfer speed is alright again... Could low transfer speed be related to higher cpu load and temperature? I mean I don't really have cpu intensive stuff running on my HC2 but maybe higher temperature makes it clock down? I'll definetly reapply thermal paste.... it's sad that they don't do that properly ex works.

    [Odroid HC2] Bad file transfer speed after omv update?

    I read that and also tried to massage the soc to improve the contact. Last time I checked, temp was ok but yeah the board recently did some downloading and copying. I'll think about reapplying thermal paste. Can't be that hard difficult right? I'd buy some thermal paste, take the soc of the enclosure, clean the old thermal paste with some rubbing alcohol and apply new none. Old kernel...yeah, I don't know how to switch to the new one or if I even should.. I thought if it's a good idea to change, arbian will do it automatically after apt upgrade. I don't really know how to do these tests with iozon and iperf3, I can monitor it and hope the tranfer speed recovers.

    S Sure: http://ix.io/16d1
  8. Hi, yesterday I did a apt upgrade and noticed that my omv install also got updated. Now copying from my HC2 I only get like 50 mb/s. I always got like 100 mb/s..at least win explorer showed this, I know it's not accurate. Could the update have erased/overwritten all these nice tweaks @tkaiser made for us to increase tranfer speed? That would be very unfortunate :/ Any chance I can roll back the omv update?
  9. Thx for your help, now everything works like I want it to
  10. I can't get it to work in service files. I just added this at the bottom for testing: [Manager] CPUAffinity= 1 2 3 then systemctl daemon-reload restart the process and look up the pid. Then with ps -o pid,psr,comm -p PID check it. But here I see a different core assigned then 1,2 or 3. I also tried creating /etc/systemd/system/unit.d and create a .conf file in it with just the manager part, also didn't work. I don't know what I'm doing wrong. Starting the app from console with taskset works.
  11. Thx, I didn't even think about that. I also have one service in /etc/init.d/, I think that's sysvinit. Is there something like this also for sysvinit you know of?.. I tried googling it but didn't find anything. ( Don't know if I understood that. I noticed that in my apps I can specify the path to unrar. My idea is to change it to a script: `/path/to/unrar_bigcores.sh` And in the script just put: #!/bin/bash taskset --cpu-list 4,5,6,7 /usr/bin/unrar But I don't know what the apps will do with this. I guess they somehow have to add the archive to extract and the location to that unrar path..
  12. I learned that the cpu on my hc2 has 4 'slow' cores and 4 fast ones. Now I would want certain apps to always use the fast cores. I found `taskset` to do so. My idea was to just add `taskset --cpu-list 4,5,6,7` in the .service file of the desired app in the execstart line in front. To have it always use the big cores. Would this work? Also I have apps 'calling' unrar to extract files. I don't know how I would do it in this case. I think it'll be a bit complicated to tell the apps to call unrar with `taskset --cpu-list 4,5,6,7`. Is there a way to have unrar always run on the big cores?

    ODROID HC1 / HC2

    Thx for the review. Sounds good to me. I'll connect my second 3,5" hdd which is in an usb 3.0 enclosure to the usb 2.0 port. Did you happen to test the transfer speed through usb 2.0 port? I guess it's 30 mb/s..or even faster? Basically I just need to access and play back fullhd video files from the external hdd. It's full and nothing gets stored on it. Won't be any problem, right?

    [preview] Generate OMV images for SBC with Armbian

    Oh no, I hope this doesn't mean you completely stop doing your reviews alltogether I'm waiting for the upcoming odroid HC2 and wanted to make a purchase dependent on a review of yours including its nas capabilities. I also plan to use an omv armbian image with possible tweaks of yours... I guess I'll have to use the existing one for xu4/hc1/mc1 and hope there's not significant changes in upcoming odroid HC2
