Linux The GNU/Linux operating system is blessed to have sound partition management tools like GParted which are very easy to use. However, when it comes to the management of 'virtual partitions' known as volumes, things are quite different. There is Linux Volume Management, or LVM for short, however it can only really be used from the command line.

The closest thing in LVM would be the volume group, but it also incorporates data integrity and redundancy (cloning, multi-disk mirroring, software raid5 and software raid6 but without the "raid write-hole" issue). It allows you to make all you drive space available to all your filesystems, without having to guess how much each one will need when you create them (they all have access to all the space in the pool, unless you put quotas on the FS). The FS all inherit a bunch of properties (record size, compression, mount options, NFS share options, etc) from their parents as well, something that LVM can't do.
