對于學習磁盤分區，通常學習的都是fdisk命令當然，對于小于2TB的磁盤，我們基本上是使用fdisk命令進行分區下面就簡單介紹一下fdisk操作磁盤的基本命令和場景模擬常用命令介紹?fdisk-l查看所有磁盤信息?fdisk/dev/sdb?使用fdisk命令工具操作/dev/sdb磁盤?m?顯示所有的命令信息、用法?p?顯示分區信息?q?退出?w?保存分區信息，只有執行了w命令后才會把分區信息寫入到磁盤?d1?刪除磁盤的第一個分區場景模擬有一個1G的磁盤/dev/sdb分區為一個主分區，一個擴展分區，大小都為200M其中在擴展分區上面建立一個100M的邏輯分區/dev/sdb5格式化文件系統為mkfs.ext4實現開機自動掛載到目錄/backup31使用fdisk命令工具操作磁盤/dev/sdb??fdisk/dev/sdb2創建一個主分區????Command(mforhelp):n??Commandaction??e?extended??p?primarypartition(1-4)?p?Partitionnumber(1-4):1?Usingdefaultvalue1?Lastcylinder,+cylindersor+size{K,M,G}(1-130,default130):+400M??Command(mforhelp):p?disk/dev/sdb:1073MB,1073741824bytes?255heads,63sectors/track,130cylinders?Units=cylindersof16065*512=8225280bytes?Sectorsize(logical/physical):512bytes/512bytes?I/Osize(minimum/optimal):512bytes/512bytes?diskidentifier:0x0004a98a??DeviceBoot???Start????End???Blocks?Id?System?/dev/sdb1???????1?????52???417658+?83?Linux3創建一個擴展分區?Command(mforhelp):n?Commandaction??e?extended??p?primarypartition(1-4)?e?Partitionnumber(1-4):2?Firstcylinder(53-130,default53):?Usingdefaultvalue53?Lastcylinder,+cylindersor+size{K,M,G}(53-130,default130):+400M?Command(mforhelp):p?disk/dev/sdb:1073MB,1073741824bytes?255heads,63sectors/track,130cylinders?Units=cylindersof16065*512=8225280bytes?Sectorsize(logical/physical):512bytes/512bytes?I/Osize(minimum/optimal):512bytes/512bytes?diskidentifier:0x0004a98a??DeviceBoot???Start????End???Blocks?Id?System?/dev/sdb1???????1?????52???417658+?83?Linux?/dev/sdb2???????53????104???417690??5?Extended4創建一個邏輯分區?Command(mforhelp):n?Commandaction??l?logical(5orover)??p?primarypartition(1-4)?l?Firstcylinder(53-104,default53):?Usingdefaultvalue53?Lastcylinder,+cylindersor+size{K,M,G}(53-104,default104):+100M?Command(mforhelp):p?disk/dev/sdb:1073MB,1073741824bytes?255heads,63sectors/track,130cylinders?Units=cylindersof16065*512=8225280bytes?Sectorsize(logical/physical):512bytes/512bytes?I/Osize(minimum/optimal):512bytes/512bytes?diskidentifier:0x0004a98a??DeviceBoot???Start????End???Blocks?Id?System?/dev/sdb1???????1?????52???417658+?83?Linux?/dev/sdb2???????53????104???417690??5?Extended?/dev/sdb5???????53?????66???112423+?83?Linux?5保存?Command(mforhelp):w?Thepartitiontablehasbeenaltered!?Callingioctl()tore-readpartitiontable.?Syncingdisks.6對磁盤進行分區?[root@hsj2~]#mkfs.ext4/dev/sdb1mke2fs1.41.12(17-May-2010)Filesystemlabel=OStype:LinuxBlocksize=1024(log=0)Fragmentsize=1024(log=0)Stride=0blocks,Stripewidth=0blocks104448inodes,417656blocks20882blocks(5.00%)reservedforthesuperuserFirstdatablock=1Maximumfilesystemblocks=6763315251blockgroups8192blockspergroup,8192fragmentspergroup2048inodespergroupSuperblockbackupsstoredonblocks:????8193,24577,40961,57345,73729,204801,221185,401409Writinginodetables:doneCreatingjournal(8192blocks):doneWritingsuperblocksandfilesystemaccountinginformation:doneThisfilesystemwillbeautomaticallycheckedevery31mountsor180days,whichevercomesfirst.?Usetune2fs-cor-itooverride.?//esfirst.?Usetune2fs-cor-itooverride.ok，搞定本文來自系統大全為您提供如需轉載請注明！推薦win10下載
