I’ve been running a few VMs on Proxmox, including a Pfsense VM, for over a year without a single issue. This evening, however, I noticed that I wasn’t able to access any local DNS records due to the VM hosting DNS server was not responding. On checking the Proxmox console, I could see that that VM with ID 102 was definitely not responding. So, I tried to reboot, stop and even reset. None of which worked. Knowing that Proxmox is based on or using KVM, I guess there must be many commands that can be run directly on the Proxmox host itself. ...

This is just a quick note on how to run Redis as a container using Podman on Ubuntu 22.04 (i.e. there will be no mention about SELinux.) Create a persistent volume for the Redis container I like storing all data/volume for containers under /srv/data. So I’ll create a sub-directory called redis-data under the same location. # mkdir -p /srv/data/redis-data Pull the Redis image # podman pull docker.io/redis Create and run the Redis container # podman run -d --name redis_server \ -v /srv/data/redis-data:/var/redis/data \ -p 6379:6379 redis Create systemd service for the Redis container I like creating a systemd service to enable/start the container. ...

While checking the root partition on my desktop today, I noticed that its usage is at 89% with just 6GiB free. For this reason, I wanted to find out what’s consuming most spaces and whether I can clean it up a bit. # df -h / Filesystem Size Used Avail Use% Mounted on /dev/mapper/fedora_watamem-root 56G 47G 6.3G 89% / The first two commands that come to my mind are du and ncdu. In this post, I’ll use ncdu to investigate the disk usages on the ‘/’ partitions. ...
