If you’ve accidentally deleted a file in Linux, don’t worry, you can probably still restore it as long as that area of disk has not yet been overwritten. This post will show you how to easily restore a deleted file in Linux.
Foremost is able to search a disk or raw image file to recover files based on their headers, footers, and internal data structures.
The New Technology File System (NTFS) is a proprietary file system created by Microsoft and is used extensively in Microsoft’s Windows operating systems.
By default most Linux distributions are not able to mount NTFS, however it is possible to install a driver that allows us to do this so that we can read and write data to an NTFS disk.
Here we’re going to cover how to find out what is using disk space in Linux with the ‘du’ disk usage command.
This command is extremely useful for tracking down large files, allowing you to find large files and free up precious disk space.
We can configure storage reports with File Server Resource Manager (FSRM) in Windows Server 2016 to generate various useful reports. These reports allow us to get a high level overview of the file shares on the file server.
In this example we’ll show you how to configure storage reports in Windows Server 2016, however the steps are very similar to older versions of the Windows operating system.
Here we’re going to show you how to convert a VHD file to a VMDK file using VBoxManage, which is part of VirtualBox and is freely available.
Swap space is an area of disk that is used to store memory to. Here we’ll take a look at managing swap space in Linux by determining what is actually using the swap space, controlling how frequently swap space is written to, and finally adding additional swap space if required.
In this example we shrink the file system of a volume in Windows Server 2016, freeing up space which can be used to create a new partition, or otherwise further decrease the size of the virtual disk to reclaim the space assuming the hypervisor supports this action.
This post will cover how to increase the disk space for a Windows Server 2016 virtual machine running in VMware, however the steps apply to any virtualization solution.
First we’ll increase the size of the actual virtual disk that is attached to the virtual machine, followed by making the required changes in the operating system in order to take advantage of the additional space from the hard disk expansion.
The server can stay online while the disk space is upgraded with this method which is ideal for most production servers, there’s no need to perform a system reboot.
By default the size of a /boot partition in Linux is not that big, 512mb or so is quite a typical default. This space is used to store different versions of the Linux kernel that you have concurrently installed at the same time.
If this space fills up you may not be able to perform a kernel upgrade in future so it is important to not let it fill and free up space in /boot.
The XFS file system generally does a pretty good job at keeping itself clean and tidy, however it can still get fragmented over time. Here we’re going to show you how to check the level of fragmentation in place on your XFS file system and how you can defragment it if required, further increasing disk performance.
