Linux CentOS is popular for those needing a professional server operating system (OS) like well-respected Red Hat Enterprise Linux (RHEL) but without commercial support. Though both are built upon the Linux Fedora OS, CentOS is a free community-driven rebuild of Red Hat started in March 2004. There isn’t a set duration between new version releases but CentOS recommends full backups and fresh installations to new versions. CentOS 6 receives updates until November 2020.
Supported File Systems
According to Red Hat documentation, CentOS supports the following file systems: ext3, ext4, global file system 2, XFS, NFS, and FS-Cache.
