This article mainly introduces "how to recover the loss of fstab files in the Linux system". In the daily operation, I believe that many people have doubts about how to recover the loss of fstab files in the Linux system. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts of "how to recover the loss of fstab files in the Linux system". Next, please follow the editor to study!
The / etc/fstab configuration file determines how the Linux system loads the partitions after startup. If the partition cannot be mounted, the system will not be able to start successfully. The following error message will appear when starting.
Solution to missing / etc/fstab files
1. Use to enter first aid mode, due to the lack of fstab files, the CD will not be able to find the Linux partition to be repaired
two。 Find and mount the root partition manually
3. Restart the system after rebuilding the fstab configuration file
4. Scan the logical volume in the shell environment in emergency mode to find the root partition device, then mount the root partition manually and rebuild the fstab configuration file (if there are no logical volumes in the system, omit the steps)
Specific operation steps
1, enter the first aid mode
2. Check the partition of the system fdisk-l
3. Check the label name corresponding to each partition and use the e2label command
4, create a temporary directory / tmpdir, and mount the root partition to / tmpdir. Because the / etc/fstab file is under the root partition. (note: if the root partition uses a logical volume, first find the logical volume, then activate the logical volume, and then mount it.)
5. In the / tmpdir/etc/ directory, recreate the fstab file, which can be created by referring to the fstab file of other Linux systems
At this point, the study on "how to recover the loss of fstab files in the Linux system" is over. I hope to be able to solve your doubts.
