Re: STICKY: PINN - An enhanced version of NOOBS.

The speed displayed on download is in megabytes per sec, but it's measuring the number of bytes written to disk after decompressing the files, so the actual network download speed will be less than that. I can't explain your slow download speeds. I only have 39Mbps FTTC, but it's still a lot quicker...

Re: Fast Raspberry Pi Car Bot Running Companion

You could base your design on a standard off-the-shelf 1/10th scale radio controlled model car. It has all the basic components: chassis, wheels, motor, servo for steering, electronic speed controller etc. Just use a raspberry Pi with a servo controller to control the steering servo and electronic s...

@epoch1970 - Yes, a FUSE file system like mergerfs may be the best solution for those users. @prthorsenjr - Using OMV does not preclude the use of LVM. In fact, OMV includes a plugin for LVM so it integrates very well, allowing you to manage your lvm virtual groups and drives etc from within OMV's w...

Fstab is ok. It's using partition label names to determine where the partitions are so no mods needed.

Re: Ubuntu from SSD - easy method

Good work. An easy fix, unlike some of the OSes I come across.
You may want to look at /etc/fstab on sda2 as well and check those references still refer to the correct drives. They may, or may not, need updating.

Re: Raspberry Pi 4b, 2 Seagate 4TB USB External Drives and lvm2

When you mentioned a "unioning" file system, I first thought of overlayfs, and how that can be used to overlay a readonly filesystem with writeable files that can be thrown away to restore the original content. But a quick read of the provided link indicates mergerfs is a bit different and could be ...

Re: Ubuntu from SSD - easy method

This only works if the boot partition identifies the location of the rootfs partition using some consistent method, such as by partition label. (I know Ubuntu Mate uses this approach, which makes it impossible to have more than one instance of the OS on your storage devices.) Normally the location o...

Re: Raspberry Pi 4b, 2 Seagate 4TB USB External Drives and lvm2

How are you powering the HDDs? Do they have their own power supplies, or are you powering them from the Raspberry Pi USB ports? The Raspberry Pi is limited in what current it can deliver over USB, so the addition of the 2nd HDD might over power it if they don't have their own supply. In this case, t...

Re: STICKY: PINN - An enhanced version of NOOBS.

It sounds like you are nearly there. What you are missing is the fixup of the partition references that is normally done by the partition_setup.sh script. You will need to edit /cmdline.txt on retropie's boot partition, and /etc/fstab on Retropie's root partition. Currently they will refer to the fi...

If you want a smaller boot partition, you need to change it from FAT32 to FAT16 or FAT12. All of these types are bootable.

I'm not sure how you are converting a .tar.gz to an .img file on a Windows machine. You can't just change the extension, it is a totally different file format. I didn't convert Alpine for use with PINN (that was thanks to Matt), but I suspect you just ungz/untar it to an already formatted SD card. W...

That is what I was used to with Noobs 2.7.0, but 3.3.1 does not allow. That's odd. I know of no reason why 3.3.1 or the Pi4 would prevent this. I will have to test.

Yes you can edit the config.txt file on a PC, but IT IS available in NOOBS. You must first select which OS you want to edit the config.txt file of to enable the button, even if you have only one OS installed.

Re: Raspberry Pi 4 usb boot?

Booting from a Pi4 is a little slower than a pi3b anyway. I think this is due to loading bootcode.bin from eeprom. Generally starting the boot from SD card is faster than a USB boot because the GPU has to wait for an SD card to timeout before looking for USB boot. But operationally, running off USB ...
