  • How to Repair Corrupted XFS Filesystem with xfs_repair

    Originally created by Silicon Graphics, the XFS file system is a robust and high-performance journaling filesystem that was first included in the Linux kernel in 2001. Since then, the popularity of the filesystem has grown exponentially, and by 2014, the XFS filesystem found its way into major Linux distributions. As a matter of fact, XFS is the default filesystem in Red Hat- based distributions such as RHEL, CentOS, and Rocky Linux. The filesystem works incredibly well with huge files and is popularly known for its speed and robustness.

    As robust as the XFS filesystem is, it is not immune to suffering filesystem corruption. Common causes of filesystem errors or corruption include un-procedural or ungraceful shutdowns, NFS write errors, sudden power outages and hardware failure such as bad blocks on the drive. Corruption of the filesystem can cause grave problems such as corruption of regular files and can even render your system unable to boot when boot files are affected.

    A few tools are useful in checking filesystem errors. One of them is the fsck command (Filesystem Check). The fsck system utility tool verifies the overall health of a filesystem. It checks the filesystem for potential and existing errors and repairs them alongside generating a report. The fsck command comes pre-installled in most Linux distributions and no installation is required. Another useful system utility used for rectifying errors in a filesystem is the xfs_repair utility. The utility is highly scalable and is tailored to scan and repair huge filesystems with several inodes with the highest possible efficiency.

    In this guide, we walk you through how to repair corrupted XFS filesystem using the xfs_repair utility.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
