Partitioning Supported tools:
MBR disks: fdisk GPT disks: gdisk To force the Red Hat installer to use GPT, add inst.gpt to the kernel commandline.
Don’t convert MBR partitions of a boot-disk to GPT, grub2 will fail to locate stage2 of the boot image.
KB: base-10 (1000x1000) KiB: base-2 (1024x1024)
fdisk fdisk saves partition info in MBR => first 512 bytes of disk gdisk GUID disk identifier gdisk saves partition metadata in first MB and a backup in last MB 128 possible partition entries Shows 2048 sector boundaries => optimal 1MiB rounding for optimal performance Update kernel partition info partprobe partition size adjustments: reboot
