Let us shrink an ext2/3/4 File system with resize2fs. With the support of our Server management support services at Bobcares we will now go through the whole setup process.

Shrink an ext2/3/4 File system with resize2fs: Setup

A division that was created and whose name we know. Run cat cat /etc/fstab to verify the name. The first field is the partition name.  Now we have to follow the steps given below to steps this feature easily..

1. Firstly, unmount the file system partition if it is presently mounted. This is the first step in the whole Shrink an ext2/3/4 File system with resize2fs set up process. Follow the example given below:

   Example

   ~]# umount /dev/vdb1
2. After that, on the unmounted file system, run fsck. Follow the example given below to get a clear picture of the whole setup Shrink an ext2/3/4 File system:

   Example

   ~]# e2fsck /dev/vdb1
e2fsck 1.41.12 (17-May-2010)
Pass 1:Checking inodes, blocks, and sizes
Pass 2:Checking directory structure
Pass 3:Checking directory connectivity
Pass 4:Checking reference counts
Pass 5:Checking group sumary information
ext4-1:11/131072 files (0.0% non-contiguous),27050/524128 blocks
3. After that, With the resize2fs/dev/device size size command, we can shrink the file system.

   Example

   ~]# resize2fs /dev/vdb1 200M resize2fs 1.41.12 (26-Mar-2023) Resizing the filesystem on /dev/vdb1 to 204800 (1k) blocks. The filesystem /dev/vdb1 is now 204800 blocks long.
Accepted size units for file system block sizes are:
S - 512 byte sectors
K - kilobytes
M - megabytes
G - gigabytes
4. Remove and rebuild the file system’s partition to the appropriate size. This will lead to the final step to Shrink an ext2/3/4 File system.
5. Finally, mount the partition and file system.

Example>
~]# mount /dev/vdb1 /ext4-1
