Linux fstab file modification causes the system to fail to start.

Linux fstab file modification causes the system to fail to start.

It is intended to modify the automatic Mount/dev/sda5 to/u01 in Linux and change it to/dev/sda5/weblogic.

Therefore, the fstab file/u01 was modified to/weblogic, so the tragedy occurred. The Mount error cannot be found at startup. after entering the repair filesystem mode, you want to modify/etc/fstab, the results file is read only, and the process of solving the problem is beginning.

Solution:

1. An error occurred while starting linux. Enter the root account password and enter repair filesystem #. Note that the fstab file cannot be saved and modified when it is fixed.

2. Privilege Escalation to root

3. mount/-o remount

At this time,/etc/fstab can be modified. This step is the core content.

4. Modify the fstab file vi/etc/fstab

If the fstab file breaks down, you can restore it if you have a backup. If not, you can write a copy on your own. The key is to know the partition information and the previous information.
