Multipathing (MPIO - Multipath I/O) is crucial for high availability and performance in iSCSI storage environments. It allows multiple network paths between a server (initiator) and a storage target, ensuring failover and load balancing. In this guide, we will configure iSCSI multipathing manually on Linux without Ansible. 1. Why

Setting up iSCSI storage manually across multiple servers can be time-consuming and error-prone. By leveraging Ansible, we can automate the installation, configuration, and persistent login of iSCSI initiators, ensuring consistency and reliability across all nodes. 1. Introduction to iSCSI Initiators iSCSI (Internet Small Computer System Interface) allows servers (initiators) to

Running out of space on your Linux VM? No problem—LVM (Logical Volume Manager) and VMware vSphere make disk resizing straightforward. In this post, I'll walk you through the process of resizing LVM-managed disks, focusing on adding capacity to an existing disk in a vSphere environment. Why Use

Sometimes the required disk space for an application or service is greater than initially anticipated. To prevent having to reinstall and reconfigure the server to suit your disk space needs, we can expand the filesystems with extra space that was added by adding an extra physical disk and use it
