centos6超20TB磁盘的分区格式化的示例代码
一、服务器环境配置：
1、检查磁盘分区：
近期项目有个服务从虚拟机迁移到物理机，服务磁盘用户自己做了raid为3.8TB2块磁盘配置Raid1然后又3.8TB6块磁盘配置了Raid5，安装操作系统使用的sda3.8TB空间的raid1已分区。3.8TB*6的磁盘sdb共20TB的空间需要分区，并挂载给系统做存储使用。步骤如下:
1.1查询确认sdb状态：
#fdisk-l WARNING:GPT(GUIDPartitionTable)detectedon'/dev/sda'!Theutilfdiskdoesn'tsupportGPT.UseGNUParted. Disk/dev/sda:4000.2GB,4000225165312bytes 255heads,63sectors/track,486333cylinders Units=cylindersof16065*512=8225280bytes Sectorsize(logical/physical):512bytes/4096bytes I/Osize(minimum/optimal):4096bytes/4096bytes Diskidentifier:0x00000000 DeviceBootStartEndBlocksIdSystem /dev/sda112673502147483647+eeGPT Partition1doesnotstartonphysicalsectorboundary.

Disk/dev/mapper/VolGroup-LogVol00:2531.7GB,2531690283008bytes 255heads,63sectors/track,307793cylinders Units=cylindersof16065*512=8225280bytes Sectorsize(logical/physical):512bytes/4096bytes I/Osize(minimum/optimal):4096bytes/4096bytes Diskidentifier:0x00000000 Disk/dev/mapper/VolGroup-LogVol01:1468.0GB,1468006400000bytes 255heads,63sectors/track,178474cylinders Units=cylindersof16065*512=8225280bytes Sectorsize(logical/physical):512bytes/4096bytes I/Osize(minimum/optimal):4096bytes/4096bytes Diskidentifier:0x00000000
1.2、sdb磁盘分区：
#parted/dev/sdb GNUParted2.1 使用/dev/sdb WelcometoGNUParted!Type'help'toviewalistofcommands. (parted)print#查看当前分区 Model:LSIMRSASRoMB-8i(scsi) Disk/dev/sdb:20.0TB Sectorsize(logical/physical):512B/4096B PartitionTable:gpt NumberStartEndSizeFilesystemName标志 (parted)mkpartprimary0%100%#将磁盘所有空间分为一个区 (parted)print#再次查询磁盘分区 Model:LSIMRSASRoMB-8i(scsi) Disk/dev/sdb:20.0TB Sectorsize(logical/physical):512B/4096B PartitionTable:gpt NumberStartEndSizeFilesystemName标志 11049kB20.0TB20.0TBprimary (parted)quit 信息:Youmayneedtoupdate/etc/fstab.
1.3、正确格式化的方法：
a、使用mkfs命令（如下）格式化是无法格式化的，检查为mkfs.ext4无法格式化16TB以上的分区，原因为Centos6.10e2fsprogs版本为1.41.12，需升级为1.42版本
mkfs.ext4/dev/sdb1#无法如此格式化
b、升级e2fsprogs版本：
tarzvxfe2fsprogs-1.42.10.tar.gz cde2fsprogs-1.42.10 mkdirbuild cdbuild/ ../configure make makeinstall##如有“忽略”错误正常。
c、查询需要分区的扇区大小
#df-h Disk/dev/sdb:20001.1GB,20001125826560bytes 255heads,63sectors/track,2431665cylinders Units=cylindersof16065*512=8225280bytes Sectorsize(logical/physical):512bytes/4096bytes I/Osize(minimum/optimal):4096bytes/4096bytes Diskidentifier:0x00000000 DeviceBootStartEndBlocksIdSystem /dev/sdb112673502147483647+eeGPT Partition1doesnotstartonphysicalsectorboundary.
d、对磁盘重新格式化命令如下：
#mke2fs-O64bit,has_journal,extents,huge_file,flex_bg,uninit_bg,dir_nlink,extra_isize-i267350/dev/sdb1 mke2fs1.42.10(18-May-2014) Warning:thefs_typehugeisnotdefinedinmke2fs.conf Creatingfilesystemwith48830868484kblocksand76298240inodes FilesystemUUID:74dabc93-177b-4531-aab9-e55a1e2efe9d Superblockbackupsstoredonblocks: 32768,98304,163840,229376,294912,819200,884736,1605632,2654208, 4096000,7962624,11239424,20480000,23887872,71663616,78675968, 102400000,214990848,512000000,550731776,644972544,1934917632, 2560000000,3855122432 Allocatinggrouptables:完成 正在写入inode表:完成 Creatingjournal(32768blocks):完成 Writingsuperblocksandfilesystemaccountinginformation:完成 Thisfilesystemwillbeautomaticallycheckedevery34mountsor##提示180天问题 180days,whichevercomesfirst.Usetune2fs-cor-itooverride.
e、解决180天问题

1.4、挂载磁盘：
a、挂载磁盘
#cd/ #mkdirdata #mount/dev/sdb1/data #df-Th FilesystemTypeSizeUsedAvailUse%Mountedon /dev/mapper/VolGroup-LogVol00 ext42.3T12G2.2T1%/ tmpfstmpfs32G144K32G1%/dev/shm /dev/sda1ext4477M41M412M9%/boot /dev/mapper/VolGroup-LogVol01 ext41.4T70M1.3T1%/home /dev/sdb1ext419T20K18T1%/data
b、设置开机挂载
在文件尾部增加一行如下内容，需注意实际的文件路径。
vim/etc/fstab /dev/sdb1/dataext4defaults00
