There are differences in the partitioning and file system formatting of large data disks and small disks. The market must use the GPT partition format, can no longer use the small disk MBR partition format. mbr partition format: The largest supported 2 TB disk. gpt partition format: Maximum supported 18 eb. For large disks on the Linux system, also use the GPT partition format, can also, the disk as a whole device without partitioning. In the Linux general use of XFS or EXT4 to do the market file system. Partition management on a disk you can use parted to partition a disk on Linux . 1, fdisk -l can see if the disk exists, because the use of large disk,fdisk can not be used as a partition tool, but should use parted. # fdisk -lwarning: gpt (guid partition table) detected on '/dev/ SDB '! THE UTIL FDISK DOESN ' T support gpt. use gnu parted.disk /dev/sdb: 17679.7 gb, 17679696003072 bytes256 heads, 63 sectors/track , 2141037 cylindersunits = cylinders of 16128 * 512 = 8257536 bytessector size (logical/physical): 512 bytes / 4096 bytesi/o size (minimum/optimal): 4096 bytes / 4096 bytesdisk identifier : 0x00000000device boot start end blocks id system/dev/sdb1 1 266306 2147483647+ ee GPTPartition 1 does not start on physical sector boundary.2, use parted to partition /dev/sdb .

The following parameters are common parameters, users can adjust according to their own needs. For 16TB above the market, for the ext4 format used by the Toolkit e2fsprogs version is required. If the e2fsprogs version is too low, such as: e2fsprogs 1.41.11, the following error message will appear: Mkfs.ext4: size of device /dev/md0 too big to be expressed in 32 bits using a blocksize of 4096.
