Mounting NFS share with Systemd Automount

On my main workstation running Fedora 36, I use both autofs and Systemd automount to mount NFS on demand. Gradually, I’m leaning toward just to use Systemd automount. Here is just a brain dump with an example of mounting an NFS share with Systemd autmount. Though, I had done this before, I found this blog post, available at [1], provides details on how to do this. Assumption The NFS server and share: banan....

How to Enable Proxmox Guest Agent

I recently had a need to run Proxmox Virtual Environment (7.2-4) at home for a project. So far everything seemed to be straight forward, partially thanks to KVM technology used in Promox. However, I also learned a few things along the way too. The first thing that I had look up on the Internet to get it working is to activate (Promox) qemu-guest-agent. If you’re reading this, it’s likely you didn’t get it working on first trial either....

Start and Stop Network Service on FreeBSD

How to delete disk partitions on Windows using PowerShell

Today I just added an old SSD to a Windows machine to use it as a back up drive. With old disks, usually they come with existing data, and I wanted to get rid of it. The problem is I couldn’t figure out how to do this using the Disk Management, the native GUI application used to manage disks. The problem could be simple to Windows users. Basically, when I right-clicked on the 2 partitions (450 MB and 100 MB) on Disk 0, there is no option to remove them....

Turn on bluetooth on login screen in Tumbleweed

After taking a very long break (over a decade) from running openSUSE on my person machine, I finally got Tumbleweed installed on a spare Intel NUC machine. If you’re one of my blog readers, expect to see more contents about SUSE/openSUSE later. Today, I’m going to share how I fix the issue with bluetooth keyboard/mouse not connected to this NUC at the login screen. I can’t remember I needed to do that my main machine running Fedora, but oh well, the fix is simple enough (if you know now)....

How to Create Exfat Filesystem on Usb

I have a UBS drive formatted as fat32 because I need to share it with Linux and macOS. When I want to copy a Linux ISO file which is larger than 4GiB, this was not possible due to the limitation of fat32 filesystem. A solution is to format that USB drive with exfat filesystem. I will do this on a Fedora 35 machine, but the process should be familiar for other Linux distros too....

Create a Disk Image With dd Command

Situation: I want to re-use an external drive which already contains some data. So I will create a disk image on an external drive in case I need to copy that image back to the drive in the future. Solution: Normally, I just run dd to create an file.img when the disk is small, e.g. SD card. However, the drive capacity is 512GB. So a better option is to compress the image....

mkfs.xfs: cannot open /dev/sda1: Device or resource busy

I’m trying to create an XFS filestem on a used disk, and got into a problem. Here is the error message: # mkfs.xfs /dev/sda1 mkfs.xfs: cannot open /dev/sda1: Device or resource busy So, let’s see if I can fix it. (Spoiler alert: I think I can, even though it’s not yet done at the time of this writing.) Let’s check the partitions of /dev/sda: # parted /dev/sda print Model: ATA ST1000LM014-1EJ1 (scsi) Disk /dev/sda: 1000GB Sector size (logical/physical): 512B/4096B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags 1 1049kB 512GB 512GB ntfs 1 So, there is a partition (/dev/sda1) with 512GB in size, and its filesystem is ntfs....

Using xclip to copy terminal content to clipboard

It’s quite annoying when I know the command I can use to copy the content on a terminal to clipboard. I know, I can run man xclip, but I think it’s still easier for me to visit this page and see how to do it. For example, I want to copy the content of my ssh keypair, ed2559.pub, to clipboard, and here how it can be done: ➜ xclip -sel clip < ~/....

LVM - How to Activate or Deactivate a Volume Group

Well, I hardly need to activate or deactivate LVM volume groups. But when I do, I also hardly remember the command required to do that. So hopefully, I can refer to this post should I need to perform one of these tasks in the future. Since a volume group is activated by default when it is created, let’s start with a command to deactivate it. # vgchange -a n example_volume_group Like wise, to activate a volume group, use the following command:...
