Die Informationen oben werden nun gebraucht. Die Konfiguration sollte geprüft werden, nicht das bereits ein LVM für das Storage vorgesehen ist.

Schritt 2 - Anlegen einer neuen Partition

Hier ist es erforderlich, dass man weiß, wo der zusätzlicher Platz zu finden ist. Es gibt 2 Varianten - entweder eine neue Platte, oder eine erweiterte Platte.

In beiden Fällen, wird eine neue Partition angelegt. Hier in diesen Beispiel, wurde eine neue Platte genutzt, die auf /dev/sdb zu finden ist.

Partitionierung mit

The information above is now needed. The configuration should be checked, maybe an LVM is already planned for the storage.

Step 2 - Create a new partition

Here it is necessary to know where to find the additional space. There are 2 variants - either a new plate, or an extended plate.

In both cases, a new partition is created. Here in this example, a new disk was used, which can be found on /dev/sdb

Adjust the commands below and the partition number (for an existing disk, the partition is then no longer necessarily 1) accordingly.
