I'm gonna keep this short. I installed Omv on my Odroid HC2 via armbian-config. I messed up and now cannot get into discs or filesystems tab in Omv and cannot add new shared folder. Using a htpc script called Atomic Toolkit, I updated an app, I think nginx and by that the PHP 7.2 automatically was installed by the script. Here is the thread on Omv. I'm writing this in the hope that maybe @tkaiser or someone else may have an idea to fix this. If not, I'll start over and would like to know how I can reinstall omv. In armbian-config I tried to untick omv and continue, but this does not remove omv ..Maybe I don't have to completely remove omv. I just want to make sure I have the "armbian omv" again.

Using the usb-uart connection I now can see that the root fs isn't found. I changed the UUID in /etc/fstab but I noticed that in /boot/boot.ini in rootdev line there's the old UUID. How can I change this? What I did so far: Interrupt boot to get to this Exynos5422 # command prompt. There I typed in setenv rootdev "UUID=d30adc0f-4d9c-4d0c-b705-ed514e1e69c8". Didn't work. Created /boot/armbianEnv.txt file, put the above line in and saved. Didn't work. What am I missing here? Edit: Trying this from the documentation: Enter these commands, replacing root device path if necessary. Select setenv line with ttyS0 for serial, tty1 for keyboard+monitor (these are for booting with mainline kernel, check boot.cmd for your device for commands related to legacy kernel): setenv bootargs init=/bin/bash root=/dev/mmcblk0p1 rootwait console=ttyS0,115200 # or setenv bootargs init=/bin/bash root=/dev/mmcblk0p1 rootwait console=tty1 ext4load mmc 0 0x49000000 /boot/dtb/${fdtfile} ext4load mmc 0 0x46000000 /boot/zImage env set fdt_high ffffffff bootz 0x46000000 - 0x49000000 If I type in this: ext4load mmc 0 0x49000000 /boot/dtb/${fdtfile} I get file not found error. Trying a specific file from /boot/dtb (I guess exynos5422-odroidhc1.dtb is the right one) also does not work -> file not found. I was being naughty and edited /boot/boot.ini even though it's stated it shouldn't be edited. Now the system successfully boots.

I now bought the more expensive one from odroid for 16€.. since all I could find provide 3.3 or 5V whereas the odroid can only handle 1.8V. Saw a vid where someone installed a LDO Regulator to get to 1.8V but since I live in a capital where there's no electronics store () I'd have to order such LDO seperately so I went straight for the odroid one.

Is there detailed info somewhere how to do so? Like I posted here I once prepared a new sd card with armbian, poped it in to have the system resize to full sd card storage and then restored the rsync backup. Back then I was successful restoring the backup on hummingboard. Now I tried with odroid hc2 backup via ssh. Turns out you have to be root on the client if you pull a backup via ssh, else the files and folders user,group and permission won't be transfered. Also after restore I changed the UUID in /etc/fstab to the new sd card. Since I first set up armbian with a fresh install I should also have u-boot on it. Unfortunately system does not boot on my odroid hc2 (or maybe just to some point). I feel like I'm missing some tiny thing... I also zero'd out the first 1M of the sd card and formated it before seting up fresh armbian. After restoring I checked the sd card and the permission, user, and group of all files and folders are correct. Right now I also have no way to see any output, I think I have to get some usb-uart module like this and connect it to my pc. Right now with new sd card I have solid red led (power), blue led and green led. After short time blue Led should start blinking and also green led and the hdd should spin up...which does not happen. Also I cannot connect the the hc2 via ssh. I cannot figure out what I might be overlooking here...

Ok, since I installed omv via armbian config I thought it may be a specific error related to omv builds for armbian.

Today I wanted to upgrade from jessie to stretch, I'm following this website. After changing the word jessie to stretch in /etc/apt/sources.list and in every file in /etc/apt/sources.list.d/* I noticed that changing the omv-extras-org.list from: # OMV-Extras.org deb https://dl.bintray.com/openmediavault-plugin-developers/erasmus jessie main # OMV-Extras.org Testing deb https://dl.bintray.com/openmediavault-plugin-developers/erasmus-testing jessie main to # # OMV-Extras.org deb https://dl.bintray.com/openmediavault-plugin-developers/erasmus stretch main # OMV-Extras.org Testing deb https://dl.bintray.com/openmediavault-plugin-developers/erasmus-testing stretch main causes apt-get update to throw errors. So I decided to leave jessie in there for now. Ok now apt-get update precedes until the line: Get:23 http://httpredir.debian.org stretch/non-free armhf Packages [71,2 kB] Fetched 10,7 MB in 8s (1.310 kB/s) and leaves me with a plain cursor. Now if I hit Ctrl+C I get the following output on screen: root@hc2:~# Traceback (most recent call last): File "/usr/sbin/omv-mkaptidx", line 113, in <module> "uri": pkg.candidate.uri, File "/usr/lib/python3/dist-packages/apt/package.py", line 567, in uri return next(iter(self._uris())) File "/usr/lib/python3/dist-packages/apt/package.py", line 550, in _uris yield indexfile.archive_uri(self._records.filename) File "/usr/lib/python3/dist-packages/apt/package.py", line 309, in _records if self.package._pcache._records.lookup(self._cand.file_list[0]): KeyboardInterrupt I see some python and omv error Can anyone help? I hoped for a painless upgrade and the first problems are appearing even before the "main course"

Thx for the info and sry for my last question in the wrong thread Could you guys recommend any procedure for updating jessie to stretch? There's so much out there. So far I only updated ubuntu versions and as far as I remember it was sth. like apt-get dist-upgrade... Is that what you meant by standard way, @Igor? Background: Really don't wanna mess up my current install, but yeah I have an up to date rsync backup in case sth. goes wrong.

Just stumbled upon this and realized I also run debian jessie. Does EOL mean it will not receive an update to 4.14 kernel? Maybe it's time to switch to strecht anyways. Is there an easy way to switch from jessie to stretch..or will it be tied to incompatibilities and other issues?

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

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.

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.

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.

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.

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.

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?

Thx for your help, now everything works like I want it to

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.

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..

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?

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?

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

Sry just found omv thread and edited my previous post :/

Which ones will be interesting in your opinion? Helios4 looks interesting but I may not even need 2 hdds...Maybe I'll swap hdds and sell the wd my cloud with 3tb hdd in it. Is there a 1 hdd solution that comes to your mind? I also thought of buying the odroid hc1, the hdd enclosure has an esata port, maybe I could hook up the external hdd to the sata port of the hc1 with sata to esata cable.. Unfortunately I saw that there's no "omv armbian" image for the hc1, .. I don't know if I can do that myself. But the hc1 should be as powerful as the xu4, it has the same SoC. Only cooling worries me here. Edit: Ok, just found your thread on omv forum where you state the xu4 name image is also for hc1/hc2/mc1 and read that hardkernel wants to release odroid hc2 for a 3,5" hdd by the end of this month. I will post following questions in this thread, fits better.

.... so much info in so little link. Thanks for that....For me as a beginner the XU4 Cloudshell 2 combination seemed perfect + on their website they advertise copy speeds via network of ~ 100 mb/s and nothing about loose connections etc.. Well, now I'm exactly where I started off.... Btw. thx also for the insight about sd,hdd and emmc performance. This all confirmes my decision to stay with armbian as os. But now I again don't know which hardware I should use. Pardon me to get off topic but since it seems to me that you're the "diy nas" expert here I want to ask for your advice I have too much devices lying around (probably you have more lying around ) and plan to replace them with...well..idealy one SBC and an enclosure: -) WD My Cloud 6TB, single bay NAS (I'm unhappy with the os, I just needed a new HDD and it was a good offer) -) "old" 3TB HDD in external USB 3.0 enclosure hooked up to NAS via USB port -) Hummingboard i2eX (you're probably familiar to that board) working as my home server -) dirt cheap S905X china box running libreelec working as my media center I think I will stay with the S905X box, it works really good with libreelec. All other devices should be replaced. I would like to take my two hdd's, put them in a case along with a SBC and use this as a NAS/homesever combo. File transfer of ~ 100-110 mb/s via gigabit lan would be really nice. The homeserver is running dl/torrent servers like transmission, nzbget, jdownloader2 | managers like sickrage,radarr,htpcmanager and also unrar at a decent decompressing speed would be nice. All of that + NAS functionallity...... Do you think it's doable or am I dreaming of an "egg-laying wool-milk-sow"? The Rock64 seems promising, but do you think it will be able to handle the homeserver jobs?
