This is just a quick note to jot down what I did to resize and expand a ZFS partition to entire disk. I never had to do this before; it tured out it was quite easy. First ensure that the autoexpand option is set on the zpool. Then, stop the VM in order to resize the disk volume. [root@phnomaural ~]# zpool set autoexpand=on immich [root@phnomaural ~]# poweroff [root@phnomaural ~]# Connection to phnomaural closed by remote host....
I’ve started to running more containers in my homelab with Podman, running inside AlamaLinux. Most of the times, things just worked. However today, I tried to setup similar containers on OpenSUSE Leap 15.16 host, and I came across an issue getting containers to communicate with one another. Well, spoiler alert, I found a solution, hence this blog post. TL;DR - install cni-plugin-dnsname package from cni-plugin-dnsname build service. (No package from the official OpenSUSE repo)....
While trying to upload a file to a web app using NGINX as a reverse proxy, I encountered the following error: ...

Occasionally, I need to look up my own public IP for various reasons. To do this, I would google “what is my ip”, and got a result on the browser. Recently, I found a way to easily do this using curl command to an easy to remember URL ifconfig.io. Here is an example, of course with the fake IPs as the results: ➜ curl ifconfig.io 2444:3444:20a:5310:d6c9:ffff:fef1:7777 To get the IPv4, we can supply the -4 option to curl command:...
I want to install ‘Hack Nerd Font’ on my laptop running Fedora 40. As of today, there is no RPM package that I am aware of that provides this font. Therefore, I would need to download and install the font manually. Visit the Nerd font website, to choose a preferred font. I like Hack Nerd Font. It can be downloaded from the Download link. Unzip the downloaded (e.g. Hack.zip) and move or copy the directory to ~/....
Well, I recently learned that one of my VMs had its root partition full. The following document on the root partition was resized on that VM. It’s not gonna be something exciting or anything special. However, I feel like I should document anyway, in case I forget on how to do that in the future, and partly due to I no longer work with these type of work as my daily job anymore....
Well, I don’t currently really have a good reason to replace a working cron job with systemd-timer beside practicing it. The following is the existing cron task for www-data user. I want to convert this cron to a systemd-timer: $ sudo crontab -l -u www-data # m h dom mon dow command */5 * * * * php -f /var/www/nextcloud/cron.php The above output indicates that the command php -f /var/www/nextcloud/cron.php is run at every 5th minute, of course by www-data user....
For my test Kubernetes cluster, Longhorn is used as the persistent block storage. The installed version is 1.6.2, and the version 1.7.0 is available now. So today, I’m going to share how to perform the Longhorn upgrade using Helm. I’m going to try to do this live as usual. Of course, I already created snapshots for all my K8s nodes in case thing goes south. First, let’s verify the current installed version of Longhorn [1]....
Earlier today while performing the update on my Fedora desktop, I encountered an issue with the new kernel update. As a result, the initramfs was not generated for the new installed kernel. So, I’ll share with you how to rebuild or generate the initramfs while fixing real issue on my Fedora workstation. First, here is an output showing the source of the issue. It might not be clear of what’s going on, but that’s okay as it’s not the main focus of this blog post....
A short while back, I had to do a revision about process life cycle in the operating system, Linux specifically. Last time that I had to learn about this topic was back in the good old days in college. I don’t know when I need to review it again, so I think it’s a good idea to dump what I’ve learned including the references to this topic. Also, I will only focus mainly on the 5-state model....
