VMware虚拟机中,Linux系统下挂载、卸载新硬盘的方法.doc

VMware虚拟机中，Linux系统下挂载、卸载新硬盘的方法 装载：1、启动vm，选择vm-Settings,按向导添加一块SCSI磁盘。进入Linux系统。2、 fdisk -l 会看到有一块新的设置,如果你先前有一块硬盘(sda1, sda3.),新加的这块应该是(/dev/sdb)。 rootlocalhost # fdisk -lDisk /dev/sda: 8589 MB, 8589934592 bytes255 heads, 63 sectors/track, 1044 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System/dev/sda1 * 1 13 104391 83 Linux/dev/sda3 14 1044 8281507+ 83 LinuxDisk /dev/sdb: 8589 MB, 8589934592 bytes255 heads, 63 sectors/track, 1044 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesDisk /dev/sdb doesnt contain a valid partition table 3、分区： rootlocalhost # fdisk /dev/sdbDevice contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabelBuilding a new DOS disklabel. Changes will remain in memory only,until you decide to write them. After that, of course, the previouscontent wont be recoverable.The number of cylinders for this disk is set to 1044.There is nothing wrong with that, but this is larger than 1024,and could in certain setups cause problems with:1) software that runs at boot time (e.g., old versions of LILO)2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK)Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)Command (m for help): mCommand action a toggle a bootable flag b edit bsd disklabel c toggle the dos compatibility flag d delete a partition l list known partition types m print this menu n add a new partition o create a new empty DOS partition table p print the partition table q quit without saving changes s create a new empty Sun disklabel t change a partitions system id u change display/entry units v verify the partition table w write table to disk and exit x extra functionality (experts only)Command (m for help): nCommand action e extended p primary partition (1-4)pPartition number (1-4): 1First cylinder (1-1044, default 1): Using default value 1Last cylinder or +size or +sizeM or +sizeK (1-1044, default 1044): Using default value 1044Command (m for help): wThe partition table has been altered!Calling ioctl() to re-read partition table.Syncing disks.rootlocalhost # fdisk -lDisk /dev/sda: 8589 MB, 8589934592 bytes255 heads, 63 sectors/track, 1044 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System/dev/sda1 * 1 13 104391 83 Linux/dev/sda3 14 1044 8281507+ 83 LinuxDisk /dev/sdb: 8589 MB, 8589934592 bytes255 heads, 63 sectors/track, 1044 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System/dev/sdb1 1 1044 8385898+ 83 Linux 4、格式化： rootlocalhost # mkfs -t ext3 /dev/sdb1mke2fs 1.39 (29-May-2006)Filesystem label=OS type: LinuxBlock size=4096 (log=2)Fragment size=4096 (log=2)1048576 inodes, 2096474 blocks104823 blocks (5.00%) reserved for the super userFirst data block=0Maximum filesystem blocks=214748364864 block groups32768 blocks per group, 32768 fragments per group16384 inodes per groupSuperblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632Writing inode tables: done Creating journal (32768 blocks): doneWriting superblocks and filesystem accounting information: doneThis filesystem will be automatically checked every 31 mounts or180 days, whichever comes first.
