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 It is a part of the Extensible Firmware Interface (EFI) standard proposed by Intel as a replacement for the outdated PC BIOS, one of the few remaining relics of the original IBM PC.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.
