The GFS2 cluster filesystem has proved itself as a robust and reliable filesystem for cluster use cases. Most of the recent development has been focussed on performance improvments, and improving the ease of use and deployment. This talk will cover recent developments in GFS2, but also discuss future plans too. When GFS was originally designed, it took a lot of inspiration from ext2/3 which resulted in bitmap based resource groups, and an equal height pointer tree for inode metadata.
