Arch linux usb install11/14/2023 ![]() $ udevadm info -attribute-walk -name= device_name | grep UDISKS_IGNORE You can check if one of these rules was applied with the following command and then find the corresponding conditions in the defaults: Some hardware devices, such as digital cameras, portable recorders, etc., may format usb storage in a way that results in the ignore rules to be triggered. Udev is shipped with a default set of rules, found in /usr/lib/udev/rules.d/, including one for ignoring some specific devices for various reasons. ![]() $ udisksctl power-off -b /dev/sd X Device is detected but does not register as mountable If you use udisks, you can use these commands: $ udisksctl unmount -b /dev/sd XY You should ask the system to turn it off first in order to safely remove it: # echo 1 > /sys/block/ disk_name/device/delete When you unmount the partitions, the device is still powered on. a solid-state drive (especially older) not flushing its cache buffers or updating its mapping tables, and losing data.a hard disk drive not parking its head, making a faint scratching sound while spinning out and degrading the device, or.Reason: Please advise how to automatically shut down devices after unmounting (Discuss in Talk:USB storage devices)įailure to power off a device might result in: If you have connected your USB storage device and it is not listed by lsblk but appears in the journal without being assigned a block device, see General troubleshooting#Cannot use some peripherals after kernel upgrade.Īlso ensure that your BIOS has both XHCI Handoff and EHCI Handoff enabled, but this is usually not an issue with most modern devices.ĭevice not shutting down after unmounting all partitions Troubleshooting No USB storage devices are detected Multiple mount tools facilitate mounting as a regular user. See FAT#Writing to FAT32 as normal user if you want normal user to do the mount/unmount action. If it does not work, make sure that the file system is mountable and writable as root, see the previous section for details. # mount -o gid=users,fmask=113,dmask=002 /dev/sda1 /mnt/usbstick If you want non-root users to be able to write to the USB stick, you can issue the following command: Note: See for example mount/unmount scripts using sudo. If mounting does not work, you can try to recreate the file system or even repartition the disk. If mount does not recognize the file system of the device you can try to use the -t argument, see mount(8) for details. Newly plugged-in devices are usually shown in the journal. See File systems#Identify existing file systems for details. The first thing one needs to access a storage device is its identifier assigned by kernel. ![]() If you use the latest udev, you may just plug your device in and the system will automatically load all necessary kernel modules. If you do use a custom-made kernel, ensure it is compiled with SCSI-Support, SCSI-Disk-Support and usb_storage. If you do not use a custom-made kernel, you are ready to go, for all Arch Linux stock kernels are properly configured. Getting a kernel that supports usb_storage Some ports might not share the same controller, preventing you from mounting the device. In my case, I downloaded via HTTPS from a mirror in the US.Note: Before you decide that Arch Linux does not mount your USB device, be sure to check all available ports. You can grab it in a number of ways from the ArchLinux download page. Download ISOįirst we need to download the ArchLinux installation ISO. ![]() All commands below are run from the Terminal. This post will cover how to create a bootable ArchLinux USB stick on macOS (in my case Catalina 10.15.7). We will use this to boot into ArchLinux and do a complete install. The first step, which I’ll cover here, is creating an ArchLinux USB installation stick. I decided to document my process in case anyone else wants to do something similar on Mac hardware. There is information on installing ArchLinux onto Macs, but some of it is years old. In my case, I am installing on an old MacBook Air, which can present some unique challenges. There is a ton of information online around working with ArchLinux. I decided on ArchLinux as it seems to be well regarded and is bare bones, built for people who want to learn how things actually work, and want to freedom and flexibility to build and configure the exact system they want. I have some old laptops laying around that I’m not currently using, so I figured I would spend the weekend and install Linux one of them. I have been wanting to learn a bit more about Linux, and see if it could maybe work for me as a day to day machine for general development and usage. ![]()
