EPEL, CRB, and GlusterFS (supported by the CentOS SIG comunity) repositories to be installed on the systems.
Firewall configuration to allow GlusterFS service with Firewalld.
Create a cluster volume with 3 file replicas. It uses file replication, not block replication. Replicated volumes.
STEP 1) Install the additional repositories.
Three additional repositories should be installed – all of them are official from the CentOS community or Fedora official community, so there tend to be really stable and do not break the package integrity. Keep on reading!
CentOS Stream 9 CRB repository is the name of the repository, which replaces the old CentOS Stream 8 PowerTools repository. enable CRB The CRB is an official repository, which stands for CodeReady Linux Builder repository. It includes multiple important packages mainly for developer packages (those with “-devel” in the name). The CRB packages may be found here: https://mirror.stream.centos.org/9-stream/CRB/x86_64/os/Packages/.
When installing packages from community official or other repositories they may depend on packages in CRB repositories, but because it is not enabled by default, there will be a nasty error of broken dependencies like:
Error:
Problem: cannot install the best candidate for the job
- nothing provides python3-pyxattr needed by glusterfs-server-11.0-2.el9s.x86_64 from centos-gluster11-test
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
The package glusterfs-server-11.0-2.el9s.x86_64 needs the package python3-pyxattr, which cannot be found in all the enabled repositories on the system, so it appears the system is broken.
So the python3-pyxattr is part of the CRB repository so just enabling it will solve the problem:
[root@srv ~]# dnf config-manager --set-enabled crb
[root@srv ~]# dnf install -y glusterfs-server

Apparently, CentOS Stream 9 installation should include EPEL and CRB repositories in addition to the base ones.
Almost half of the files are developments files (i.e. “-devel”) packages and others are additional libraries, mainly Python 3 and Perl modules, OpenJDK 17, 11, 1.8.0 slow debug and fast debug, and more.
