Linux磁盤掛載

內容是自己實際操作拷貝下來的,如有不足之處,還請指出!

------------------你好,我是分割線-----------------

[root@oracledb /]# fdisk /dev/vdb#進入磁盤初始化

Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel

Building a new DOS disklabel with disk identifier 0xc0fe6104.

Changes will remain in memory only, until you decide to write them.

After that, of course, the previous content won't be recoverable.


Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)


WARNING: DOS-compatible mode is deprecated. It's strongly recommended to

         switch off the mode (command 'c') and change display units to

         sectors (command 'u').

p#第二步

Partition number (1-4): 1#默認1

First cylinder (1-1040253, default 1): #回車

Using default value 1

Last cylinder, +cylinders or +size{K,M,G} (1-1040253, default 1040253): #回車,默認最大值

Using default value 1040253


Command (m for help): p#第三步,再次查看,下面是剛剛分出來的
