If you use Red Hat’s GFS2 (Resilient Storage), please read on….

Please be aware that starting with RHEL 10, Red Hat will no longer be shipping GFS2.  Resilient Storage Add-On will be discontinued with RHEL 10 - Red Hat Customer Portal

There are several alternative shared file systems that can be used to replace GFS2, but you need to be sure that they replacement has all the features (ACL groups, backups, …) that you are using.  A good understanding of the IO throughput that is being used to the existing GFS2 shared file system is very important to know as well.

Here is an old paper (Shared File Systems: Determining the Best Choice for Your Distributed SAS® Foundation Applications) regarding shared file systems and SAS 9.4.  The points in the paper are still valid.  Please note that some shared file systems that are being pushed NFS, CEPH, Gluster may not be good choices, especially if high IO throughput with lots of WRITEs are required of your shared file system.

If you need further assistance from SAS determining what to use as a replacement to GFS2, please work with your SAS Customer Support Manager (not SAS Technical Support) to find a resource to review the pros and cons of replacement shared file systems.

We also strongly encourage you to review the RHEL 10 release notes regarding other changes to RHEL operating system with this new version.  Any questions you have on new features or other deprecations with RHEL 10 must be addressed to Red Hat.
