Yep, and thank you to Suse, Fujitsu, and all the contributors. I suppose we can all be charitable when reading this from the Red Hat Whitepaper at:
https://www.redhat.com/whitepapers/rha/gfs/GFS_INS0032US.pdf: << Red Hat GFS is the world’s leading cluster file system for Linux. >> If that is GFS2, it is a different use case than Gluster (https://www.redhat.com/en/technologies/storage). So perhaps marketing might tweak that a little bit, maybe: << Red Hat GFS is the world’s leading cluster file system for Linux for Oracle RAC Database Clustering. >> But you can see how Oracle might quibble with that. So Red Hat goes as far as it can in the Whitepaper: << Red Hat GFS simplifies the installation, configuration, and on-going maintenance of the SAN infrastructure necessary for Oracle RAC clustering. Oracle tables, log files, program files, and archive information can all be stored in GFS files, avoiding the complexity and difficulties of managing raw storage devices on a SAN while achieving excellent performance. >> Which avoids a comparison between, say, an Oracle Sparc server (probably made by Fujitsu) hosting Oracle Rack Clusters on Solaris. Given the price of Oracle's sparc servers, Red Hat may be as good as an Oracle RAC DB server can get for a price less than the annual budget of a small country. Well, great news, Austin and Chris, that clears it up for me, and now I know of yet another use case for btrfs as the dmu for Gluster. So, again, I'm not too worried about Red Hat deprecating btrfs, given the number of supporters and developers. If Oracle or Suse drops out, then I would worry.
