This guide explains how to extend a disk partition on Rocky Linux after increasing the virtual disk size in a hypervisor such as ESXi, XCP-ng, or Proxmox.
This guide explains how to create and configure a RAM-based filesystem using tmpfs on Linux systems, including mounting, persistence, and performance testing.
This guide provides a structured approach to analyzing disk usage and safely reclaiming disk space on Linux systems using command-line tools.
Start by reviewing overall disk usage:
df -hThis shows filesystem usage in human-readable format.
This guide explains how to retrieve NVMe and storage device SMART data on VMware ESXi hosts using esxcli and shell scripting.
This guide explains how to view a network interface, reset its IP configuration,
enable DHCP using nmcli, and configure a legacy interface file on
RHEL-based Linux systems.
Use the following command to display the current network interfaces and assigned IP addresses:
This guide explains how to generate a certificate signing request (CSR), sign it using the VMware vCenter Certificate Authority (VMCA), and install the signed certificate on a vSphere Replication appliance.
This guide provides command-line methods to monitor and analyze CPU performance on VMware ESXi hosts using built-in tools such as esxtop, esxcli, and vsish.
With constantly growing email content, users need to carefully handle the amount of storage used by their mailbox. For Microsoft Exchange/Outlook users, this normally involves routine archiving of email. However some users experience problems after archiving emails where Outlook still shows the mailbox is full. The user will eventually reach their storage limit and are no longer able to send/receive further email due to the administrative limits.
Once space runs out in a LINUX based virtual machine you can easily increase the disk size in VSphere client settings, however to utilize the free space within the LINUX OS requires extending the disk file system.
For most desktop machines harddisk space is not a critical issue due to the low cost per Gigabyte of current consumer drives. Unfortunately server disks are a lot more expensive and keeping disk space small for virtual machine implementations is critical, making the ballooning system drive for Windows server an ever increasing problem.
To safely reclaim some of that space you clear out a lot (sometimes up to several Gigabytes) of disk space by clearing up Windows updates.
