Introduction
In this tutorial we learn how to install chunkfs on CentOS 8.
What is chunkfs
ChunkFS is a FUSE based filesystem that allows you to mount an arbitrary file or block device as a directory tree of files that each represent a chunk of user-specified size of the mounted file. The chunk size is global per mount, but at mount time any value can be specified. (If the file size isn’t a multiple of the specified chunk size, the last file in the tree simply will be smaller than the chunk size.) Only read access is supported at the moment. UnChunkFS is the inversion of ChunkFSu2014it allows you to mount a ChunkFS tree (or a copy of it, of course), and gives you a single file named image that has the same contents as the file or device you created the tree from by mounting it as a ChunkFS.
We can use yum or dnf to install chunkfs on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install chunkfs.
Install chunkfs on CentOS 8 Using dnf
Update yum database with dnf using the following command.
sudo dnf makecache --refresh
The output should look something like this:
CentOS Linux 8 - AppStream 43 kB/s | 4.3 kB 00:00
CentOS Linux 8 - BaseOS 65 kB/s | 3.9 kB 00:00
CentOS Linux 8 - ContinuousRelease 43 kB/s | 3.0 kB 00:00
CentOS Linux 8 - Extras 23 kB/s | 1.5 kB 00:00
CentOS Linux 8 - FastTrack 40 kB/s | 3.0 kB 00:00

CentOS Linux 8 - Plus 24 kB/s | 1.5 kB 00:00
CentOS Linux 8 - PowerTools 50 kB/s | 4.3 kB 00:00
Extra Packages for Enterprise Linux Modular 8 - x86_64 13 kB/s | 9.2 kB 00:00
Extra Packages for Enterprise Linux 8 - x86_64 24 kB/s | 8.5 kB 00:00

After updating yum database, We can install chunkfs using dnf by running the following command:
sudo dnf -y install chunkfs

After updating yum database, We can install chunkfs using yum by running the following command:
sudo yum -y install chunkfs
How To Uninstall chunkfs on CentOS 8
