mkfs.vfat: unable to open {partition}: No such file or directory (command succeeds, but throws this error and blocks rest of script)

Asked 2021-May-21 at 03:38

Update: I got this working but am still not 100% sure why. I've appended the fully and consistently working script to the end for reference.

I'm trying to script a series of disk partition commands using sgdisk and mkfs.vfat. I'm working from a Live USB (NixOS 21pre), have a blank 1TB M.2 SSD, and am creating a 1GB EFI boot partition, and a 999GB ZFS partition.

Everything works up until I try to create a FAT32 filesystem on the EFI partition, using mkfs.vfat, where I get the error in the title.

However, the odd thing is, the mkfs.vfat command succeeds, but throws that error anyway and blocks the rest of the script. Any idea why it's doing this and how to fix it?

It may take time for kernel to be notified about partition changes. Try calling partprobe before mkfs, to request kernel to re-read the partition tables.

Manjaro not showing up in systemd-boot

Asked 2021-Feb-07 at 23:13

After hours of trying I'm not able to get Manjaro (Luks, btrfs, lvm) to show up in my systemd-boot menu, and I can't figure out why.

Manjaro is set up with Luks encryption, a btrfs file system, and with LVMs. Boot manager is installed at /boot/efi

Previous to Manjaro, I was already dual booting PopOS and Windows, which were set up with systemd-boot. I have installed Manjaro with the architect image, and selected systemd-boot as the bootloader. After rebooting, the only entry that showed up was Windows. The PopOS entry I managed to fix by chroot'ing into the installation and running update-initramfs.

What I have tried:

Running sudo mkinitcpio -p linux59 inside chroot
Running sudo boot --path="/mnt/boot/efi install" from my host (Pop)
Manually adding the file /boot/efi/loader/entries/Manjaro.conf:

ANSWER

Answered 2021-Feb-07 at 23:13

Solved the issue. As the boot files were installed in /boot, but the bootloader was installed in /boot/efi, the relative path was the latter rather than the former. Solved it by copying the boot files to a dir inside /boot/efi

Nothing wrong per se. The boot partitions are usually separate for security and recoverability reasons (plus they sometimes need to be a "simple" filesystem type like FAT).

QUESTION

What Filesystem to choose for a portable SSD storing VM's to be accessed using Windows and Linux

Asked 2021-Jan-31 at 18:01

As the question already suggests I'm trying to figure out which is the best suited filesystem for my specific use case. I have bought myself a Samsung Portable SSD T5, 1 TB, for the purpose of having a fast external device which stores all my VirtualBox VM's. This way I would make them accessible for multiple devices. The problem now is that these devices are running different Operating Systems (Windows 10 and Ubuntu/Debian).

I would like to be able to run the VM's from Linux Hosts and Windows Hosts.

My first thought was to simply use FAT32, but well, it comes with its constraints regarding file size. I'm unsure about extFAT when run in combination with Linux?

I have been duckduck-going around for a while now but I'm unsure what filesystem to choose, as it also has to be very reliable.

I hope someone with more experience can help me out, thanks in advance!

I have the same situation, just a slightly different drive, I use an external ASUS ROG STRIX ARION ESD-S1C USB Type-C box and an internal M.2 ADATA SSD 512 GB (XPG SX8200 Pro 512GB). I formatted it in NTFS format, created two virtual machines on it: Windows 10 and Kali Linux, everything works more than perfectly, the speed is excellent, I do not even replace that this is not a host, but virtual machines, the fact is that a virtual machine is all no matter what format you use, since when creating a virtual hard disk for a virtual machine, you can choose the format that the virtual machine will run on in this virtual hard disk, Ext2, Ext3, Ext4 and so on.

Is formatting a USB stick to NTFS a good idea?

Asked 2020-Dec-11 at 21:20

I have a Sandisk dual drive USB stick which can be plugged into android and PC. I was wondering if I should format it to NTFS before using. I intend to use it for storing my important files from android, which are quite large. I often find my USB sticks and microSD cards becoming corrupt and unable to be read without formatting first. So I wonder if NTFS is more reliable and restorable than FAT32 for storing my important data?

Android does not support NTFS. This is from the FAQ of Transcend (a popular SD card vendor):

Android doesn't support NTFS file system. If the SD card or USB flash drive you insert is NTFS file system, it won't be supported by your Android device. Android supports FAT32/Ext3/Ext4 file system. Most of the the latest smartphones and tablets support exFAT file system. Usually, whether the file system is supported by a device or not depends on the devices software/hardware.

Please check the file system your device supports.

You might want to consider ext4 for large file sizes.

QUESTION

How to compute the value for `version made by` in zip header?

Asked 2020-Nov-24 at 09:30

I'm struggling to compute the correct value for version made by in adm-zip.

The Zip Spec is unclear in my opinion how to find the binary or int value to set an option (e.g. Option 3 Unix) to the depending 2 Bytes in the central header.

The docs from adm-zip for the header setting does not help at all.

Mapping from the zip spec (4.4.2):

4.4.2.2 The current mappings are:
...

ANSWER

Answered 2020-Nov-24 at 09:30

Short description:

According to the specification the upper byte represents the OS which created the ZIP file. The lower byte is the version of the used ZIP specification.

In your example:

788 = 0x0314

OS which created the ZIP file:
0x03 (Upper Byte): UNIX

4.4.2.1 The upper byte indicates the compatibility of the file attribute information. If the external file attributes are compatible with MS-DOS and can be read by PKZIP for DOS version 2.04g then this value will be zero. If these attributes are not compatible, then this value will identify the host system on which the attributes are compatible. Software can use this information to determine the line record format for text files etc.

ZIP specification version:
0x14 (Lower Byte): Version 2.0

0x14 / 10 = 2 (Major version number)
0x14 % 10 = 0 (Minor version number)

4.4.2.3 The lower byte indicates the ZIP specification version (the version of this document) supported by the software used to encode the file. The value/10 indicates the major version number, and the value mod 10 is the minor version number.

For Windows NTFS, the correct "version made by" value should be:

0x0A14 = 2580

0x0A (Upper Byte): Windows NTFS (Win32)
0x14 (Lower Byte): Version 2.0

Can't get U-boot running on Raspberry PI 4B. What are the absolute necessities?

Asked 2020-Sep-24 at 18:53

I saw a few posts regarding this topic, but nothing really helped my cause, and so restating my problem here.

I would like to build my own toolchain, U-boot and the mainline Linux kernel to be ported on a particular processor. Since I currently am in possession of a Raspberry Pi 4B, I decided to use it to test my binaries stage-by-stage on it.

I performed the following so far:

Built a 64-bit toolchain using Crosstool-ng (v1.24.0) - Got \x-tools\aarch64-rpi3-linux-gnu
Cloned U-boot and built v2020.07 version thereby generating u-boot.bin + other files(Built using rpi_4_defconfig and rpi_arm64_defconfig)
Cloned Linux Kernel (v5.4.65 and v5.8.9), added bcm2711_defconfig in arch/arm64/configs from the Raspberry Pi repositories and built the Linux Kernel - generating vmlinux, Image, Image.gz, System.map, bcm2711-rpi-4-b.dtb + other files
Created two partitions boot (FAT32), rootfs (Ext4) on my 32-GB SD card
Copied u-boot.bin, Kernel images, start4.elf, fixup4.dat into the boot partition
Have this in config.txt//config.txt

Uncomment below to use your custom named kernel

kernel=u-boot.bin

Serial console output!

enable_uart=1 7. Tried connecting RPi to the monitor with HDMI cable

What I see: The device seems to switch on, I see some quick green LED blinks, and then it is the red LED only that keeps steady. The monitor gets signal indicated by the fact that it brightens, but the screen is blank. I expected a command prompt with UART > or something, but nothing came.

Questions:

Can someone comment what is missing on my side?
What are the absolute minimum stuff to get an own U-Boot, own Linux Kernel and a root FS running on a Raspberry Pi 4B? (with regards to .elf, fix*.dat, etc., + the settings on config.txt, cmdline.txt? )
