Partition scheme

from Wikipedia, the free encyclopedia

In IT, a partition scheme is understood to mean two different terms that have to do with the division of volumes into partitions . The term is the German translation of the English partition scheme or partitioning scheme .

Partitioning

The partition scheme is used in all operating systems as a synonym for partition table and LVM . A physical data storage device , a physical volume , is divided into smaller logical areas, so-called partitions or logical volumes , which can be used by one or more operating systems ( multi-boot systems ). While partition tables only provide for division into smaller partitions, an LVM partition scheme can, conversely, divide multiple physical data stores into one or more larger partitions. In addition, an LVM can be partitioned dynamically - this means that data stores can be removed and added during operation. This partition scheme is therefore also referred to as “dynamic disk” under Windows from Microsoft .

Partition layout

The term for the division of a Unixoid system into separate partitions according to the Filesystem Hierarchy Standard (FHS) is also common. Here, individual directories as separate partitions in the system involved (see also mount ) what u. a. Brings advantages in reinstallation, data backup and the optimization of individual file systems . Under FreeBSD this type of partitioning is called partition layout, under Debian GNU / Linux it is called partitioning scheme .

With many Linux distributions, for example, it is customary to use a separate partition for the root directory , which can be formatted safely during a new installation, as it does not contain any documents created by the user. In order for the previous statement to be correct, these in turn have to be on a separate partition for the user directories , which is /homeintegrated under . Likewise, u. a. also /usr/localfor local installations, /optfor additional non-distribution installations, or even e.g. B. /varbe integrated as separate partitions. Since the file system of the partition can be severely fragmented through frequent writing of log files , this effect has no effect on the other partitions and their file systems due to its own partition. It's the same with swap partitions . /var

Under macOS , the number of partitions to be created can be selected in the “Partition layout” tab in the hard disk utility.
