Logical volumes are one of Linux’s methods of getting greater flexibility. These are how the Operating System can use the physical drives within a computer. While under traditional partitioning you would create fixed partitions of primary or extended types within a disk. With Logical Volume Management (LVM), you can create partitions that can span over multiple physical drives and be moved, resized and backed up – all without having to stop a running system while doing so.
There’s no doubt that the principles of streaming have revolutionized modern entertainment. No longer is it necessary to wait patiently for an appointed hour to watch a particular program; no longer are games passive experiences played offline in isolation. Cloud-hosting pioneers like Netflix and Steam have introduced streaming into modern media consumption, and our lives are undoubtedly richer for it.
When working with logical volumes in Linux for file systems, one of the big advantages that it brings is the ease of resizing volumes along with the ability to do so on the fly. In previous articles we’ve looked at logical volume management detail and covered the terminology involved. We’ve also set up and configured a basic logical volume system for use, so this time we’ll look at how you can go about resizing your logical volumes.
The number of data breaches compromising user passwords over recent years has highlighted that relying on passwords alone for authenticating your users isn’t enough if you really want to be secure. The solution to this is called multi-factor authentication (2FA).
The broadcasting industry is going through big changes as OTT (‘over the top’) content continues to disrupt the sector’s traditional business models. OTT represents a big opportunity for content broadcasters, providers and distributors large and small. They can deliver streaming video-on-demand direct to viewers over the web, rather than via broadcast, cable or satellite TV. But to make an OTT model work effectively, media businesses are going to have to get far better at handling big data.
In the beginning, there was YouTube. And it was good. So good, in fact, that an entire industry has developed around streaming video services. Over the top video content (OTT) is one of the world’s fastest-growing consumer markets; industry leader Netflix is now available in almost 200 countries, while arch-rival Hulu recorded 30% growth last year.
Over the years since its release, Java has become one of the most popular cross-platform development languages. It ‘s behind blockbuster games like Minecraft through to the server side software such as Google’s Gmail. Basically, Java is ubiquitous.
Logical volumes provide a great deal of flexibility in how you can manage your filesystems on a Linux dedicated server or VPS. In a previous article, we looked at the advantages that Logical Volume Management (LVM) can bring over using traditional partitions for your Linux system, as well as some of the terminology involved in using logical volumes. This time we are going to build upon that and look to set up LVM on a pair of disks added to an existing system.
