We have lots of &nbsp;linux machines and little disk space. &nbsp;<br />
<br />
Most of our hosts are ESX although we have physical linux boxes also.<br />
<br />
In the past we have installed rpm files that messed up the box and have problems getting them back up to get the rpm back off the box. <br />
<br />
Can we do a lvm snapshot before and roll it back if there is a problem. &nbsp;<br />
<br />
As I understand a vmware ESX snapshot takes as much disk space as the original disk ( it is pretty much a mirror of the orignal machine ). &nbsp; We have little disk space and clearly can not do the snapshot on the vmware side. &nbsp;Snapshots on netapp filers take less than 1% of the disk space. &nbsp;LVM snapshots likely fit somewhere between. &nbsp;Does someone know how much space ( overhead ) a lvm snapshot takes <br />

Can I use an lvm snapshot to &quot;undo&quot; an rpm install ?

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.

Linux

A Linux distribution is an operating system made as a software collection based on the Linux kernel and, often, on a package management system and are available for a variety of systems. A typical Linux distribution comprises a Linux kernel, GNU tools and libraries, additional software, documentation, a window system (the most common being the X Window System), a window manager, and a desktop environment. Most Linux systems are open-source software made available both as compiled binaries and in source code form, allowing modifications to the original software. Over three hundred distributions are in active development, including commercially backed distributions (such as Fedora, openSUSE and Ubuntu) and community-driven distributions (such as Debian, Slackware, Gentoo and Arch Linux).

Linux Distributions

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
