Changes will remain in memory only, until you decide to write them. After that the previous content wont be recoverable.The number of cylinders for this disk is set to 488386. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs(e.g., DOS FDISK, OS/2 FDISK)Command (m for help): m Command Action a toggle a bootable flag b edit bsd disklabel c toggle the dos compatibility flag d delete a partition l list known partition types n add a new partition o create a new empty DOS partition table p print the partition table q quit without saving changes s create a new empty Sun disklabel t change a partitions system id u change display/entry units v verify the partition table w write table to disk and exit x extra functionality (experts only)这里制作测试一个区够用不再进行分区。 分好区后可以通过fdisk -l查看分区情况 [rootRK356X:/]# fdisk -l Found valid GPT with protective MBR; using GPTDisk /dev/mmcblk0: 30547968 sectors, 2628M Logical sector size: 512 Disk identifier (GUID): f4420000-0000-426c-8000-368900004ad5 Partition table holds up to 128 entries First usable sector is 34, last usable sector is 30547934Number Start (sector) End (sector) Size Name1 16384 24575 4096K uboot2 24576 32767 4096K misc3 32768 163839 64.0M boot4 163840 294911 64.0M recovery5 294912 360447 32.0M backup6 360448 25526271 12.0G rootfs7 25526272 25919487 192M oem8 25919488 30547903 2259M userdata Disk /dev/nvme0n1: 477 GB, 512110190592 bytes, 1000215216 sectors 488386 cylinders, 64 heads, 32 sectors/track Units: sectors of 1 * 512 512 bytesDisk /dev/nvme0n1 doesnt contain a valid partition table [rootRK356X:/]#这是识别到的nvme盘信息就一个分区。 Disk /dev/nvme0n1: 477 GB, 512110190592 bytes, 1000215216 sectors 488386 cylinders, 64 heads, 32 sectors/track Units: sectors of 1 * 512 512 bytes 三、格式化 硬盘分好区后要格式化才能正常挂载 系统自带了格式化工具mkfs.ext4可以直接使用。 [rootRK356X:/]# mkfs.ext4 /dev/nvme0n1 mke2fs 1.46.5 (30-Dec-2021) /dev/nvme0n1 contains a ext4 file systemlast mounted on Thu Jan 1 08:15:21 1970 Proceed anyway?
