Welcome to GNU Parted! Type 'help' to view a list of commands.Ĭreates a new GPT disklabel i.e. To create a partition start GNU parted as follows: ![]() The nixCraft or author is not responsible for data loss. These examples may crash your computer if executed. Therefore, always keep verified data backups before you create a Linux partition larger than 2 Terabytes on a live system. WARNING! Typing the following Linux commands modifies your hard disk drive, and there is a chance of data loss if you enter the wrong commands or use the wrong block device name. I/O size (minimum/optimal): 512 bytes / 512 bytesĭisk /dev/sdb doesn't contain a valid partition table How to create a Linux partition larger than 2 Terabytes (TB) Sector size (logical/physical): 512 bytes / 512 bytes Please note that almost all new kernel and latest distro supports GPT. Set CONFIG_EFI_PARTITION to y to compile this feature. However, if you are using Debian or Ubuntu Linux, you need to recompile the kernel. By default, Redhat Enterprise Linux / CentOS comes with GPT kernel support. If you don’t add GPT support in Linux kernel, after rebooting the server, the file system will no longer be mountable, or the GPT table will get corrupted. You must include GPT support in the kernel to use GPT. Imaged Credit Wikipedia) Linux GPT Kernel SupportĮFI GUID Partition support works on both 32bit and 64bit platforms. LBA addresses that are negative indicate position from the end of the volume, with −1 being the last addressable block. Each logical block (LBA) is 512 bytes in size. (Fig.01: Diagram illustrating the layout of the GUID Partition Table scheme. EFI uses GPT where BIOS uses a Master Boot Record (MBR). It is a part of the Extensible Firmware Interface (EFI) standard proposed by Intel as a replacement for the outdated PC BIOS, one of the few remaining relics of the original IBM PC. Partition Table (GPT) is a standard for the layout of the partition table on a physical hard disk. It supports Intel EFI/GPT partition tables. To solve this problem use, GNU parted command with GPT.
