    The end is me stopping the scrub. Is this an indication that the power supply needs replacing?

     

    edit: Maybe the hard drive instead...

  2. Weird. Are you saying those SD cards fail to boot with high speed support and succeed at normal?

     

    Weird thing is, I have a lexar SD card here that is not compatible (probably because it's UHS-1). My USB SD card reader can read it.

  3. Anyone know why it's not supported out of the box? The wiki provides a patch but does not mention why it's not upstream or in Armbian.

     

    The bus-width being 4 is also quite suspect. All the other Armada 38x devices have it at 8. Armada 37x ones have it at 4.

  4. It should probably be tested beforehand.

     

    Again, he tested "iperf -P 4" with swconfig on an armada device. He doesn't remember if it was the armada 37x or 38x. Clearfog devices are only the latter I believe.

     

    edit: ehm I'm getting full speeds when I tested this. I think he tested this on the older 37x platform.

     

    edit2: second posibility: iperf from one device connected to the switch to another connected to the switch. I tested from the helios device itself to a router (mvebu 385 platform running OpenWrt).

  5. Unrelated but one of the patches that I removed seems to actually be useful.

     

    I just talked to Felix Fietkau and according to him, it seems the mvneta driver does not do any hardware queue configuration, leading to a nasty performance problem. Testable with iperf -P 4. Not iperf3.

     

    Although the equipment he tested on did have a switch. The Helios4 does not.

     

    I don't think the way I'm using mine it matters a whole lot though.

  6. Is it me or it the mv_xor driver being loaded late?

     

    ```

    ```

     

    I see that /proc/interrupts shows no action despite me using RAID5.

     

    edit: from looking at kernel source, it seems btrfs uses xor_blocks instead of async_tx. The former seems software only.

  7. I tried to install ZFS on my Helios 4. Gave me some 32-bit kernel error. So btrfs it is.

     

    Anecdote: my Helios 4 has survived probably over 100 kernel freezes (because of broken DFS patches) and btrfs scrub finds no problems. bittorrent verify also shows no problems.

     

    Overall, I'm satisfied with btrfs. Now as a user of OMV, I would love OMV 6 with btrfs support :).

     

    edit: I will also note this is with RAID5, which is strongly recommended against.
