      my point is, I miss the old Raspbian images and its little bit strange to switch to the Arabian image, which is build from someone who bash permanent the raspberry pi
      Sorry, can't help you with your understanding problems :)

      In my opinion it's pretty easy to get that any Raspberry Pi is the most lousy SBC possible for NAS use cases since bottlenecked by 'single USB2' and suffering from underpowering problems. No idea how this can be missed if you look more closely at the hardware?

      Then what do you not understand wrt focusing on OMV users? Why shouldn't we care about users any more?
      • Since the RPi is such a lousy choice for a NAS it's important that users be aware of that. So they can choose optimal hardware for the use case they're interested in
      • Since an awful lot of users have already an RPi lying around why not trying to provide them with the best OMV experience possible? Why not letting RPi users too benefit from our 'OMV on ARM devices' journey that started almost a year ago? Why should we exclude them?
      If you're not able to understand how limited every RPi out there is when it's about NAS usage then I'm sorry but I fear nobody can help you. Same with asking to exclude the many RPi users from good software. Why should this happen? Why shouldn't RPi users also be able to run 'best OMV possible'?

      Or are you asking for fanboy behaviour? Sorry, impossible.

      BTW: Since there's a potential performance problem with the freshly announced RPi 3 B+ I thought it's a good idea to both check for this issue with RPi folks and to prepare a new OMV image for RPi that already supports the new board (needs a new 'firmware'), is based on OMV4 and contains the few missing tweaks from the other ARM images.

      I ordered an RPi 3 B+ an hour ago but canceled it right now and deleted the preparations for the new OMV4 image. Thanks for the reminder that it's simply not worth the efforts with this target audience :)
    • C'mon @tkaiser.

      Lot's of people stumble onto OMV, by the impulse purchase of a Raspberry PI.
      (It's kind of like the first junker car young folks buy until they realize that, by "saving money", they've bought into a lot of mechanical problems.) With that experience in hand, the second time around, generally they do better.

      An R-PI is a kind of "gateway" device. When new users learn about an R-PI's limitations, many buy better hardware.
      (I'd have to include myself in that group.)
      Good backup takes the "drama" out of computing

    • For users of freshly released RPi 3 B+


      Since RPi Foundation changed hardware requiring both new 'firmware' and kernel support the currently available OMV image won't boot on the new board. Symptom looks like undervoltage when a display is connected (displaying the yellow lightning bolt) but it's simply the old firmware refusing to boot the new hardware.


      So it's necessary to replace the entire contents of the /boot partition (FAT partition so accessible from a PC or Mac too) with this: web.archive.org/web/2018031517…mp/ZCLu0r/RPi_3B_Plus.tgz (archive created with most recent Raspbian Lite image -- please do NOT touch/replace cmdline.txt, see below)


      This should then boot the RPi 3 B+ with latest RPi 4.9.80 kernel, as usual a network connection is needed and the installation will finish itself (depending on the random IO performance of the SD card used this might take between 10 and 40 minutes). Whole procedure is not tested so you're on your own :)

      Edit: Silly me forgot to add that if you already have an RPi 2 or 3 then booting the OMV image there and applying all available updates (happens at 1st boot anyway) should also lead to an image that is ready for the RPi 3 B+ -- the necessary updates for kernel and bootloader are part of RPi's Stretch repos which the OMV image is able to use (via apt pinning).


      Edit 2:


      ATTENTION:


      The above archive contains cmdline.txt from Rapsbian Lite image which should not be used since referencing the rootfs via an UUID not matching the rootfs from our image and also contains 'init=/usr/lib/raspi-config/init_resize.sh' which can't work. So please exclude cmdline.txt when replacing the files on the /boot partition

    • While a bit off topic:

      @tkaiser, note that I'm saying this with true sincerity.

      I appreciated both your skill set and grasp of the issues that surrounding the R-PI (and this newest version), and SBC's as a whole class of computing devices.

      These wrinkles and twists that the OEM's throw out there, represent real effort to fix or remediate. Most users don't understand the level of effort required in development, not so much in the time required for a single fix, but in the gathering of the skills necessary to come up with solutions. (Years, even decades of experience are required.)

      While there will always be a few who lack the understanding of what is involved in developing these images, there are scores more who appreciate being able to boot a NAS operating system on a SBC.

      I'm one of them so let me say "Thanks" for a job well and skillfully done.

    • On the subject of the new RPi 3 B+......

      I have updated an existing OMV installation on a RPi 3 as per @tkaiser's post above.

      That worked fine and dandy.

      I put the SD card from this RPi into a new RPi 3 B+.


      Would you expect it to just work?


      It boots up to a command line login prompt but the system itself seems not to be working (I cannot access it through a browser). Also, the static IP address it was running on the older machine is not being used.


      Any pointers very much appreciated.
    • To cover the base;
      (Since existing installs can get "dirty" with use.)

      How about building a new install from scratch, on an R-PI 3 (where all of the latest updates are applied before the first boot). Then, with no configuration or alterations, moving it to the 3 B+ ?

      This is speculation, but worth a try.

    • Yeah, I know how that is. :)

      The build is short, about 15 minutes of time, and then leaving it alone for an hour or so to be safe is easy enough. It's the (re)configuration that can take a good bit of time.

      In any case, you could try it with a spare SD-card as a test.
      If you don't have a spare SD-card - you really need one. (To clone the boot drive.)

    • Hello,


      I am new to this forum and only users of OMV. I have a new RPi+ and would like to build a small NAS. With an old pi I could create a bootable image. Sounds good!. The pi boots and I can configure it via the webgui. But there are issues with media playback. The pi seems to lose connection to either the HDD or the network or it has an hardware issue. The stream stops after minutes. The stream also stops when rewinding and rewinding. Maybe someone can help. Thank's!

      With NFS I get this error
      ntfs-3g[8720]: Failed to read $MFT bitmap: Input/output error
      kernel: [ 2702.857586] Buffer I/O error on dev sda5, logical block 20, async page read

      Structure:
      Pi 3+ (Pi3 power supply)
      HDD with external power supply

      What was I trying to do:
      NFS/FTP/SMB all the same issue
      Separate HDD, Separate power supplies

      This configuration runs on the old Pi 3 without issues!

      Not in my opinion for two reasons:
      1 - raid shouldn't be used on an RPi
      2 - OMV doesn't create raid arrays using partitions

    • Important to know for RPi B 3+ users!

      Now that we provide a new OMV image for RPi that also contains an updated ThreadX (that's the primary operating system running on all RPi euphemistically called 'firmware') and updated kernel+device-tree stuff booting the OMV image on latest RPi is possible. If you're interested in all the hassles and details here you go: forum.openmediavault.org/index.php/Thread/22185

      The important bits:
      • On first boot we limit RPi B 3+ to just 600 MHz since an awful lot of RPi installations uses insufficient powering leading to voltage drops under load that result in instable behaviour (freezes, crashes, kernel panics, data corruption). Staying at 600 MHz results in lower consumption so under-voltage can not be triggered that easy. After the installation has been finished and the Pi reboots one time, OMV checks for under-voltage and only if this hasn't occured RPi 3 B+ will be unlocked to full performance (1400 MHz).
      • By default networking on RPi B 3+ will remain at 100 Mbits/sec. An awful lot of users replacing an older Pi with their new 3+ uses insufficient Ethernet cabling resulting in lower throughput and/or weird network problems. If you think this is not an issue in your installation feel free to edit one single config file to allow for Gigabit Ethernet (though speed improvements are not that great anyway, it's still 'shared USB2' and GbE NAS performance will be only a fifth of what all the better ARM boards provide)
      For all the following steps you need SSH access to your OMV box or display and keyboard. In any case use the web interface first and create there a new user account being member of both 'sudo' and 'ssh' groups. Afterwards you can login with this user through SSH (e.g. using the Putty program on Windows, built-in ssh command everywhere else) or at the console.

      To check for under-voltage do a 'sudo cat /var/log/raspihealth.log' or 'sudo raspimon' as explained on the first page of this thread. If you have an issue you need to fix it. This is a hardware issue. Buy a good PSU providing a stable 5.2V to your board, for example the official RPi PSU if you haven't already. Amperage ratings of the PSU are more or less irrelevant as long as they exceed 2A since the RPi problem is called 'voltage drop'. The power circuitry is that bad that you can't feed more than 2A anyway so all you have to take care of is a stable voltage provided to your Pi (cheap PSU don't, average Micro USB cables don't -- that's why a good PSU with a fixed and thick cable with low resistance is mandatory)

      In case you want to enable Gigabit Ethernet you need to edit /etc/rc.local and put a '#' in front of the ethtool line. So you do a 'sudo nano /etc/rc.local', navigate to the bottom and edit the line so it reads like this afterwards:

      Source Code

      1. # /sbin/ethtool -s eth0 speed 100 duplex full autoneg on
      Save the file and reboot. If you now run into instabilities you're affected by under-voltage (Gigabit Ethernet increases idle consumption by approx. 500mW, load consumption slightly more since more data will be transmitted in less time). Switching back to Fast Ethernet will help, using a switch that is capable of EEE/IEEE 802.3az will help too (numbers)

      If your network performance is now worse than before then you have an issue with cabling. Gigabit Ethernet uses 4 cable pairs while Fast Ethernet only 2. You can have cables that work very well with 100 Mbits/sec and you achieve 95 Mbits/sec transfer speeds in this mode while activating Gigabit Ethernet with the same cables can result in way lower numbers and tons of retransmits (since the other 2 cable pairs are the problem) or even no connection any more at all (rare).

      To check for this use iperf3 (not iperf) since this tool lists not only transfer numbers but also count of retransmits (those retransmits trash the performance: TCP/IP just like any other protocol suite uses checksums to ensure data integrity. If data got corrupted at the wire the receiver takes notice and forces the sender to retransmit the packet. The more retransmits the lower the throughput. To get an idea on what's happening at lower layers -- Ethernet frames instead of TCP/IP packages -- you could run for example iperf3 in UDP mode)

    • And for anyone ever questioning our decision to limit RPi 3 B+ to Fast Ethernet by default... just read through this sad story: raspberrypi.org/forums/viewtopic.php?f=63&t=208512&start=25 (archived version)

      RPi users refusing both to test appropriately and to accept reality. If you have retransmits you have to get rid of them. Check your cable, check your switch port, eliminate the retransmits and then performance won't suffer any more.

      People who are not network experts most probably will never get the idea that latency and round-trip times matter with lost packets, that any USB2 attached Gigabit Ethernet behaves totally different compared to any real Gigabit Ethernet implementation on the other SBC and that retransmits affect connections with high round-trip times a lot more than those with short ones (higher latency adds to lower throughput when packet loss occurs -- that's simple network basics).

      Maybe I should remove the instructions above how to get the ethtool call out of the way to save us from unnecessary support hassles with reluctant RPi users? Anyone choosing a Raspberry Pi as NAS is not interested in NAS performance anyway. Fast Ethernet is totally fine for this target audience :)

      let people know that time machine backups would not work when I enabled gigabit ethernet
      TimeMachine backups work pretty well with Gigabit Ethernet on single board computers. Personally tested with these boards: Banana Pi, Banana Pro, Olimex Lime 2, Clearfog Pro, EspressoBin, Rock64, Orange Pi Plus 2E, ODROID HC1 and HC2 and an i.MX6 Wandboard.

      I don't see a reason why it shouldn't work also with the new Raspberry Pi. Are you sure you're not running in underpowering issues (Gigabit Ethernet needs more juice)? Care to provide output from 'armbianmonitor -u' and 'cat /var/log/raspihealth.log'
    • dogg!~ wrote:

      I think my power supply is ok. below is the screenshot of cat /var/log/raspihealth.log
      Yeah, no under-voltage occured so far. You might want to check this thread here discussing network problems with the new Pi: raspberrypi.org/forums/viewtop…80e47fb2f880a197&start=50

      Please remember: on every 'network equipped' Raspberry Pi there's no network in reality. It's always an integrated USB Ethernet adapter behind an USB hub (which is something you usually want to avoid). And USB on the Raspberry Pi has been a sh*t show since the early days: element14.com/community/thread/19436 -- reading through this from back in the early days it seems like a wonder that this worked somehow at all in the following years :)
