VFS: unabletomounttherootfson (0, 0) solution

This error is reported when the centos system is started. LFSkernelpanic-notsyncing: VFS: UnabletomountrootfsonUnknown-block (0, 0 );

This error is reported when the centos system of our servers is powered on after the power failure in the IDC.

LFS kernel panic-not syncing: VFS: Unable to mount root fs on Unknown-block (0, 0 );

I tried several methods to solve the problem most effectively at the beginning.

The solution is as follows:

Find the boot disk where centos is installed. you can use a USB flash disk or a CD disk to boot the boot disk.

Select "install or upgrade existing installation ";

Select a language;

Select New boot;

Select the position of the system, that is, the boot disk (there is an sda and sdb, what is not repeated is your boot disk, do not select the wrong );

If you select a boot drive, you must change it to your hard disk instead of the boot drive;

Reboot your system;

Restart;

Okay. solve the problem. you can start the instance.
