use e2label with the device name followed by the new name<br />
for example, to change the device sda1 to foo, do:<br />
<br />
<b>e2label /dev/sda1 foo</b>
</div>


use e2label with the device name followed by the new name
for example, to change the device sda1 to foo, do:

e2label /dev/sda1 foo

<div>
Technically, e2label is labeling a file system, /dev/sda1 is a file system.<br />
<br />
But you are mentioning a harddisk, this would be /dev/sda - if you do want to label a harddisk then you cannot do that with e2label.<br />
<br />
You can set the File System Volume label like this:<br />
# tune2fs -L samba /dev/sda1<br />
<br />
To show the name:<br />
# tune2fs -l /dev/sda1<br />
tune2fs 1.42.5 (29-Jul-2012)<br />
Filesystem volume name: &nbsp; samba<br />
...<br />
<br />
How do you display the current name of your harddisk?

Rename Hardisk in RHEL 6.4

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

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage

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.
