文档介绍：Linux下磁盘分区命令fdisk的使用方法fdisk是1inux下一个很实用的分区命令:查看所有磁盘分区情况[******@erpdevdb/]#fdisk-1Disk/dev/sda:,1048576000000bytes255heads,63sectors/track,127482cylindersUnits二cylindersof16065*512二8225280bytesDeviceBootStartEndBlocksTdSystem/dcv/sdal***********Linux/dev/sda266267620972857+8eLinuxLVM/dev/sda32677528720972857+8eLinuxLVM/dev/sda45288127482981531337+5Extended/dev/sda552887898209728268eLinuxLVM/dcv/+8cLinuxLVMDisk/dev/sdb:,1198899855360bytes255heads,63sectors/track,145757cylindersUnits二cylindersof16065*512二8225280bytesDeviceBootStartEndBlocksIdSystem/dev/sdbl13734930000581183Linux从以上输岀我们可以看到,目前磁盘是/dev/sda和/dev/sdb两块,当然这里看到的不是物理盘数,一般是做过"id后重新划分好的。其中/dev/sda已经有了1到6共6个分区,而/dev/sdb只有一个分区。还可以看到起始位置、块数、分区类型等信息。下而我们填加一个新的LVM分区:[******@erpdevdb/]#fdisk/dev/,butthisislargerthan1024,andcouldincertainsetupscauseproblemswith:softwarethatrunsatboottime(.,oldversionsofLILO)bootingandpartitioningsoftwarefromotherOSs(.,DOSFDISK,OS/mand(mforhelp):pDisk/dev/sda:,1048576000000bytes255heads,63sectors/track,127482cylindersUnits二cylindersof16065*512二8225280bytesDeviceBootStartEndBlocksTdSystem/dcv/sdal***********Linux/dev/sda266267620972857+8eLinuxLVM/dev/sda32677/dev/sda45288/dev/sda55288/dcv/+8eLinuxLVM127482981531337+5Extended7898209728268eLinuxLVM204001004
