  • Here comes CentOS 7 !

    Yay.. Here comes CentOS 7! A new major release of the community-supported Linux distribution which is derived from sources provided by Red Hat is announced recently. Since RHEL 7 was made available in June of this year, CentOS 7 is poped out in this month without much delay.

    As of now CentOS 7 is available for the 64 bit x86 compatible machines only and soon will be available for 32bit and other well known architectures as well. A notable feature in this new release is that it does support direct upgrade path from CentOS-6 to CentOS-7. The release notes say that "For the first time, there is a supported upgrade path from CentOS 6 to CentOS 7. This path is only supported from the latest version of CentOS 6 (being 6.5 at the time of writing) to the latest version of CentOS-7... The tools needed for this functionality are still being tested and will be released at a later time."

    For more information on upgrade, refer to the following link.

    Re: Here comes CentOS 7 !

    Good news, thanks for sharing. Btw, why Red Hat and CentOS moved to XFS as default FS, when the world is moving toward ZFS/BTRFS as default? As far as I know XFS is good for huge number of smaller files and not for larger files.

      ZFS vs XFS is like comparing Apples to Oranges Both have some unique features of their own & are used in a variety!

        I have read somewhere in whitepaper that Red Hat has worked with storage partners and customers during this selection process to test and validate XFS. There was a need of fast file system that can scale up dynamically. BTRFS is still under intensive development and there are different reasons & views about adoption of ZFS on Linux.

        The following message on rhl-list well discuss about ZFS adoption : Ten Reasons To *NOT* Use ZFS:
