  1. Helios4 Support

    I think this is expected. At PWM 0, this fan type will still run at minimum rpm. Note : standby mode is not yet fully supported. Plus there is no yet proper way to wake up, this will come later with Wakeup-On-Lan support. FYI This is the kind of question that should be rather asked on openmediavault forum. OMV3 mounts file system under /srv folder. So in sabnzd config folder you can chose/find your share folders by browsing under /srv/<mount-point-name>/<your-share-folders>. Important : Don't forget under OMV / Share Folder / ACL to give read/write permission to sabnzbd user for the share folders you wanna use.

    Hi All, As announced in our blog Debian 9 Stretch release is now available which provide the best hardware support of Helios4. For now you can find the latest build release on our wiki, link also available above in the this thread banner.
  3. Helios4 Support

    @Igor @zador.blood.stained Even though we have our own 4.4 marvell kernel repo, as agreed with Zador before, to add Helios4 support in Armbian framework we are integrating our additions/modifications via patches to armbian mvebu-default, this way all mvebu board build against the same kernel repo (which uses moonman repo). We have new stuff to be merged soon for mvebu-default, can be found here. For the mvebu-next (mainline), we are almost done also, can found the work here. Later today or tomorrow, we will rise a pull request from our armbian/build repo to update both mvebu-default and mvebu-next. Hopefully from this point you will start to build Helios4 image and make them available on your website. For the time being I will still build and maintain on our own builds as found here. Once you are making build available, then our wiki will point to your download page for baseline Jessie and Stretch build... we will then only build and maintain OMV images. @Igor Nice pic ;-) You will realize the casing is not really perfect for single disk, it needs at least 2 disks to properly hold together. You should rather put your disk in one of the middle slots.

    Main thread for general questions related to Helios4 setup and usage. Note : Before asking a question please insure the information is not already available on HELIOS4 Wiki or addressed in a previous post in this forum.

Temporary fix : Disable SPI NOR flash. SDcard High Speed timing have compatibility issue with some brands. Temporary fix : Disable UHS option/support. Legacy Kernel (4.4) : PWM-FAN driver not working. Temporary fix : Use GPIO-FAN driver, only 2 speeds supported (low or full speed). Mainline Kernel (4.14) : DVFS doesn't use correct CPU freq range (666 - 1332Mhz instead of 800-1600MHz).

I'm still trying to figure out a more concrete way to confirm that the system offload on hardware engine, but based on benchmark it does.

    @Tido I just added a share button for Google+ @wsian Even though it was the intention in the early days of the project, the OLED display is not part of the Kit. But you can order one on Aliexpress for less than $10. .Just choose any 1.3 inches OLED i2c screen with IC SSD1306. I will give more information about this topic later on. Perhaps if we find the time we might even offer it on our website as an add-on to Helios4 for a slightly cheaper price than what Aliexpress can offer.

    Awesome Helios4 is successfully funded !!! We still accept orders till the end of the campaign : July 19, 2017 https://shop.kobol.io/ Thanks for the support.
  9. Support of Helios4 - Intro

    @tkaiser The discount code (KSBACKER10) is valid till July 3rd. Like you, we were surprised to see such positive response to the ECC model, but it looks like the majority of our backers understood the added value and how it was differentiating even more the Helios4 from proprietary entry level NAS. So thank you to have suggested (many times) this upgrade ;-) Regarding 'getting more attention', it isn't that trivial unfortunately... we think that once the first Helios4 batch is received and used by our backers it will improve our exposure.

    Hi All, Hi @tkaiser Today we are running a new pre-order campaign on: shop.kobol.io To make this new campaign possible we have revisited the goal to 300 units, with a simplify offer that focuses on a single option: Helios4 Full Kit - 2GB ECC @ 195USD. To encourage this ECC upgrade and show our appreciation we also wanted to give 10$ off to our initial backers who believed in this project. So ONLY For the next 2 weeks use your discount code : KSBACKER10 and enjoy 10$ off. We’re also happy to announce that we’ve addressed the following challenges: No more confusing currency, everything is in USD With Easyship, we managed to reduce the shipping fees The Kobol Team [ kobol.io/helios4 ]

    Hi All, A little update that might satisfy some of you @tkaiser We have just introduced a new KIT with 2GB of ECC memory. We have received quite a lot of demands for an ECC option, while it was quite a premium feature (cost wise) we finally decided to offer the option for a little extra money. Only 10 days remaining to snatch Helios4. We need your support guys. http://goo.gl/ECMtQ5 Cheers.

    Hi Guys, That's nice to see the effervescence around Helios4. We have a pretty good start for the first 48hours, we are very optimistic. Thanks @tkaiser for being so proactive and already answering most people questions. I saw you were very active on CNX ;-) I have so many question to reply through KS, it's hard to catch-up. I take note of all your feedback. Regarding the HDD vibration absorbers and the filter screen, it's something I had already in mind but haven't found yet the right solution. Take note that the thickness of the acrylic plate is much ticker than usual PC metal case, so standard absorber won't fit. If I can find the right solution we might put these as part of the kit by default. Haha i see someone really wants its ECC RAM, but yes agree It would be a great stretch goal. We were also planning in the stretch goal list to include a OLED i2c screen. But well, first we need to see how the campaign progress in the next few days before dreaming too big. Cheers.
