今天在Linux系统中格式化新分区的时候,提出错误:Could not stat /dev/sda7 --- No such fileor directory,下面来记录我是如何解决这个错误的.
Linux查看已经分好的区:
[root@linuxidc ~]# fdisk -l /dev/sda Disk /dev/sda: 21.5 GB, 21474836480 bytes 255 heads, 63 sectors/track, 2610 cylinders Units = cylinders of 16065 * 512 = 8225280bytes Sector size (logical/physical): 512 bytes /512 bytes I/O size (minimum/optimal): 512 bytes / 512bytes Disk identifier: 0x7d57cb1f Device Boot Start End Blocks Id System /dev/sda1 1 2610 20964793+ 5 Extended /dev/sda5 1 128 1028097 83 Linux /dev/sda6 129 256 1028128+ 83 Linux /dev/sda7 257 384 1028128+ 83 Linux 格式化新分区的时候,报错,提示下面的错误,没有这个文件或目录.
Could not stat /dev/sda7 --- No such fileor directory The device apparently does not exist; didyou specify it correctly? [root@linuxidc ~]# mke2fs -t ext4 /dev/sda7 mke2fs 1.41.12 (17-May-2010) Could not stat /dev/sda7 --- No such fileor directory //phpfensi.com The device apparently does not exist; didyou specify it correctly? 解决方法 :执行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.
查看是否安装过该命令:
[root@linuxidc~]# rpm -q parted packageparted is not installed 提示没有安装过,则需要安装parted
安装命令: #yum install parted #前提是保证你的虚拟机可以上网,要从网络下载安装包.
[root@linuxidc~]# yum install parted Loadedplugins: fastestmirror 1234567 Loadingmirror speeds from cached hostfile * base: mirrors.skyshe.cn * extras: mirrors.skyshe.cn * updates: mirrors.skyshe.cn base | 3.7 kB 00:00 extras |3.3 kB 00:00 updates | 3.4 kB 00:00 Settingup Install Process ResolvingDependencies -->Running transaction check --->Package parted.i686 0:2.1-25.el6 will be installed -->Finished Dependency Resolution DependenciesResolved ============================================================================= Package Arch Version Repository Size ============================================================================= Installing: parted i686 2.1-25.el6 base 595 k TransactionSummary ============================================================================= Install 1 Package(s) Totaldownload size: 595 k Installedsize: 2.1 M Isthis ok [y/N]: y DownloadingPackages: parted-2.1-25.el6.i686.rpm | 595 kB 00:16 Runningrpm_check_debug RunningTransaction Test TransactionTest Succeeded RunningTransaction Installing : parted-2.1-25.el6.i686 1/1 Verifying : parted-2.1-25.el6.i686 1/1 Installed: parted.i686 0:2.1-25.el6 Complete! 安装完成后,再进行查询一次,已经安装成功.
[root@linuxidc~]# rpm -q parted parted-2.1-25.el6.i686 执行一下该命令:
[root@linuxidc~]# partprobe Warning:WARNING: the kernel failed to re-read the partition table on /dev/sda (Deviceor resource busy). As a result, it maynot reflect all of your changes until after reboot. Warning:WARNING: the kernel failed to re-read the partition table on /dev/sdb (Deviceor resource busy). As a result, it maynot reflect all of your changes until after reboot. Warning:Unable to open /dev/sr0 read-write (Read-only file system). /dev/sr0 has been opened read-only. Warning:Unable to open /dev/sr0 read-write (Read-only file system). /dev/sr0 has been opened read-only. Error:Invalid partition table - recursive partition on /dev/sr0. 然后执行格式化,就OK了,如果还提示出错,重启之后再执行格式化就可以了.
