Supercharge Volume Management With EVMS For Linux - Page 2
EVMS come with three different management interfaces:command-line, Ncurses, and a GTK-based GUI. I recommend the GUI; or if you don't want to run X use the Ncurses interface. The Ncurses and GUI interfaces are pretty much the same and a lot easier to use than the CLI, which might be useful if there are tasks you want to script, but otherwise forget it. (See these screenshots.)
As good as the graphical interfaces are, EVMS is complex, and takes some study to learn your way around. It's important to get their terminology down, so here is a quick review of basic disk terminology:
- Disk Sector
The smallest addressable bit of a physical drive, usually 512 bytes.
- Storage region
A related set of logically contiguous sectors that may not be physically contiguous.
- Disk Segment
This is what EVMS calls a hard disk partition.
- Storage object
A catchall term for physical or logical disks, disk segments, and storage regions.
- Logical Volume
A mountable storage object; in other words, this is the unit that you will mount and access like any Linux filesystem.
