Fast format of super hard disk under Linux system

MBR , all called Master Boot Record , that is, the hard Master Boot Record .

bootloader , partition table and delimited identity), That is, the bootstrapper

because the MBR partition table has a maximum addressable storage space of only 2Tb (2 32x512 bytes), so the MBR partitioning method is gradually replaced by the GUID partition table in the case of large hard disks.

globally unique identity partition table(GUID Partition Table, abbreviation:GPT) is a physical disk.standard for structural layout of partitioned tables. Support for maximum volume: 18EB, (E:EXABYTES,1EB=1024TB), up to 128 partitions per disk.

as a result of the actual implementation of the environment, the landlord encountered is 75TB of large hard disk, the normal format is certainly not complete, even if the format of the waiting time is also long, here to introduce a large hard disk support format and faster Time tool ( E2FS Programs )

E2FS Programs (also called e2fsprogs) is a Ext2 (and EXT3/4) file System toolset (EXT2 filesystems utilities[2]), which contains standard tools such as creating, repairing, configuring, Debugging Ext2 file systems, and so on. E2fsprogs is an open source software that complies with GPLV2 or LGPLV2.

Installation method:

# View the second disk name, this is/dev/sdb

[[email protected]] #fdisk –l

# partition converted to GUID partition table

[[email protected]] #parted/dev/sdb

......

(parted) Mklabelgpt

PartitionName? []? Database

File SystemType? [Ext2]?

Start? 0

End? 100%

Warning:theresulting partition is not a properly aligned for best performance.
