Reverting to Ext2 File System

by | Nov 19, 2021

Reverting to Ext2 File System can be made possible in a few easy steps. Let us discuss.

As part of our Server Management Services, we assist our customers with several Ext2 queries.

Today, let us see how we can revert its file system.


Reverting to Ext2 File System

In order to revert to an ext2 file system, our Support Techs recommend the following procedure.

In this article, we use the following value for the block device:


Moving ahead, let us have a look into the steps our Support Techs follow:

Initially, we log in as root and unmount the partition. To do so, we type:

# umount /dev/mapper/VolGroup00-LogVol02

Then we have to change the file system type to ext2. For that, we type the following command:

# tune2fs -O ^has_journal /dev/mapper/VolGroup00-LogVol02

Later, we check the partition for errors. To figure them out, we run the following command:

# e2fsck -y /dev/mapper/VolGroup00-LogVol02

Then we run the below command to umount the partition again as ext2 file system:

# mount -t ext2 /dev/mapper/VolGroup00-LogVol02 /mount/point

Finally, we replace /mount/point with the mount point of the partition.

In addition, we need to make a note to delete any .journal file that exists at the root level of the partition.

We can also permanently change the partition to ext2.

To do so, we need to remember to update the /etc/fstab file, otherwise, it will revert back after booting.

In short, we saw how our Support Techs revert to Ext2 File System for our customers.
