Re: External hard drives that no longer standby under rasbian buster

I did that and now it works. But why 120 = 10 minutes? what is this 120? You are welcome. Values from 1 to 240 specify multiples of 5 seconds, so 120 x 5 = 600 seconds, which is 10 minutes. Yup - It's explained in the man page for hdparm. I'm guessing it has to do with the way the timeout is encode...

Re: Raspi 4 file server disappointing transfer speed, degradation and segfaults

Those in the know, not me, claim BTRFS is a joke and full of problems. They go for ZFS. That was my very limited experience with BTRFS - had a two way mirror using two USB-connected SATA hard drives. One side of the mirror got corrupted and BTRFS refused to resync whatever I did. I'm now looking at...

Okay, you indicate "firmware file" (sounds singular) and that this single file then would be placed on a FAT32-formatted microSD card. I would assume that this partition needs to be marked as bootable as well.
All models of Pi ignore the 'bootable' flag - this is by design.

Re: External hard drives that no longer standby under rasbian buster

Code: Select all

sudo apt update && sudo apt install hdparm
sudo hdparm -q -S 120 -y /dev/sda
You can also put calls to hdparm in /etc/rc.local to set the standby timeout at boot - works for me. See 'man hdparm' for details.

Re: Ubuntu 19.10 (Eoan Ermine) released

The USB-problem concerning the Raspberry Pi 4GB RAM model might be due to the issue seen earlier that using more RAM than 3072 MB breaks the USB: https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=246766&start=25 The issue was solved by a kernel patch: https://www.raspberrypi.org/forums/viewto...

Re: [Pi 4B] 4k 60Hz HDMI suddenly stops, black screen, red LED going off

After an idle time of precisely 10 minutes (i.e. just booting and not doing anything for 10 minutes), the monitor is showing a black screen. The fact that it is exactly 10 minutes makes me suspect this is just the screen saver. Can you attach a keyboard or mouse and press a key or more the mouse to...

Re: Ubuntu 19.10 (Eoan Ermine) released

There also seems to be a problem with networking. On my Pi 3B and Pi 4B it fails to get an IP address from my pi-hole DHCP server - both machines work fine with Raspbian. If I manually add an IP address to eth0, a default route, and DNS servers in /etc/resolv.conf everything seems to work.

Samba does not need Java, so something else must have pulled it in as a dependency. If you start again with a fresh SD card, then install samba it will work fine.

I have a question - once I have your latest Gentoo running on my Pi 4 4GB, what do I need to do to add ZFS filesystem support? I'm guessing it's easier than trying to bolt it on the side of the official Raspbian release.

That error is not anything to do with samba - it seems to be down to you asking for a version of Java that doesn't work on ARMv6 processors. You are indeed limited to older versions of Java/OpenJDK on all ARMv6 processors, including the BCM2835 used on the original Raspberry Pi 1A and B, and the Ras...

You will occasionally see these kind of interop issues with ethernet devices, although it should be much less common than it once was. It could be a bug in your router, or a bug in the Pi. Either way you now have a solution 👍

The firmware already tries to do that to push the kernel to choose the same mode as the firmware, as that would then match any hdmi_mode/group parameters in config.txt.

On the Pi 4 we actually have firmware in both an EEPROM chip, and on the SD card. The EEPROM replaces the bootcode.bin that is used to boot other models. After that the start4.elf and fixup4.elf run off the SD card (or network, or USB mass storage once these become available) as with previous models...
