  • Linux 格式化分区 报错Could not stat --- No such file or directory 和 partprobe 命令

    【原文链接】:http://blog.chinaunix.net/uid-26557245-id-3134302.html

    分区的过程正常:

    [root@db1 /]# fdisk -l

     

    Disk /dev/sda: 21.4 GB, 21474836480 bytes

    255 heads, 63 sectors/track, 2610 cylinders

    Units = cylinders of 16065 * 512 = 8225280 bytes

     

       Device Boot      Start         End      Blocks   Id  System

    /dev/sda1   *           1          13      104391   83  Linux

    /dev/sda2              14         650     5116702+  83  Linux

    /dev/sda3             651         841     1534207+  82  Linux swap / Solaris

    [root@db1 /]# fdisk /dev/sda

     

    The number of cylinders for this disk is set to 2610.

    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)

     

    Command (m for help): n

    Command action

       e   extended

       p   primary partition (1-4)

    p

    Selected partition 4

    First cylinder (842-2610, default 842):

    Using default value 842

    Last cylinder or +size or +sizeM or +sizeK (842-2610, default 2610):

    Using default value 2610

     

    Command (m for help): w

    The partition table has been altered!

     

    Calling ioctl() to re-read partition table.

     

    WARNING: Re-reading the partition table failed with error 16: Device or resource busy.

    The kernel still uses the old table.

    The new table will be used at the next reboot.

    Syncing disks.

     

    再次查看,分区已经划好:

    [root@db1 /]# fdisk -l

     

    Disk /dev/sda: 21.4 GB, 21474836480 bytes

    255 heads, 63 sectors/track, 2610 cylinders

    Units = cylinders of 16065 * 512 = 8225280 bytes

     

       Device Boot      Start         End      Blocks   Id  System

    /dev/sda1   *           1          13      104391   83  Linux

    /dev/sda2              14         650     5116702+  83  Linux

    /dev/sda3             651         841     1534207+  82  Linux swap / Solaris

    /dev/sda4             842        2610    14209492+  83  Linux

     

    但是格式化的时候,报错:

    [root@db1 /]# mkfs -t ext3 /dev/sda4

    mke2fs 1.39 (29-May-2006)

    Could not stat /dev/sda4 --- No such file or directory

     

    The device apparently does not exist; did you specify it correctly?

     

     

    解决方法:执行下partprobe 命令

     

           partprobe包含在parted的rpm软件包中。partprobe可以修改kernel中分区表,使kernel重新读取分区表。 因此,使用该命令就可以创建分区并且在不重新启动机器的情况下系统能够识别这些分区

     

    查看是否安装该命令:

    [root@db1 dev]# rpm -q parted

    parted-1.8.1-23.el5

     

    我们执行一下该命令:

    [root@db1 dev]# partprobe

    Warning: Unable to open /dev/hdc read-write (Read-only file system).  /dev/hdc has been opened read-only.

     

    然后在格式化,就ok了:

    [root@db1 dev]# mkfs -t ext3 /dev/sda4

    mke2fs 1.39 (29-May-2006)

    Filesystem label=

    OS type: Linux

    Block size=4096 (log=2)

    Fragment size=4096 (log=2)

    1778880 inodes, 3552373 blocks

    177618 blocks (5.00%) reserved for the super user

    First data block=0

    Maximum filesystem blocks=3640655872

    109 block groups

    32768 blocks per group, 32768 fragments per group

    16320 inodes per group

    Superblock backups stored on blocks:

            32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208

     

    Writing inode tables: done                           

    Creating journal (32768 blocks): done

    Writing superblocks and filesystem accounting information: done

     

    This filesystem will be automatically checked every 38 mounts or

    180 days, whichever comes first.  Use tune2fs -c or -i to override.
