Yes, you got that right. We cannot partition a hard disk larger than 2TB using fdisk tool. - -In such cases, we can use parted command. The major difference lies in the partitioning formats that fdisk uses DOS partitioning table format and parted uses GPT format. - -TIP: You can use gdisk as well instead of parted tool. - -In this article, we will show you to add a new disk larger than 2TB to an existing Linux server such as RHEL/CentOS or Debian/Ubuntu. - -I am using fdisk and parted utilities to do this configuration. - -First list the current partition details using fdisk command as shown. - -``` -# fdisk -l -``` -[ - ![List Linux Partition Table](http://www.tecmint.com/wp-content/uploads/2017/04/List-Linux-Partition-Table.png) -][2] - -List Linux Partition Table - -For the purpose of this article, I am attaching a hard disk of 20GB capacity, which can be followed for disk larger than 2TB as well.
