The top-down approach to tuning; The history of Oracle tuning. The last two options are related to quorum and the remaining tunables are related to performance. Rsync is a particularly tough workload for GlusterFS as with the defaults it uses many of the weak points of glusterfs. In such workloads the hardware’s benefits are unrealized, so there is little return on the investment. This saves time formerly required for transferring files to and from the workstation, but also can take place at a performance level higher than can be achieved from a single local drive (mechanical or SSD). First, Thank you for your great job! I'm trying to deploy a bare-metal cluster using glusterfs over RDMA. cache=none seems to be the best performance and is the default since Proxmox 2.

But it seems clear from this comparison that most of the poor write performance for gluster-block for this workload is coming from the gluster-block group tuning profile. Data integrity issues still exist in GlusterFS, due to the way data is replicated. I have also noticed that sometimes a simple ls command on a folder with ~200 files takes multiple seconds to complete. When we tested our deployments, we got good throughput for both Lustre and GlusterFS, and performance scaled as expected as we added storage nodes. I've tried using vfs gluster_fuse, but that doesn't seem to do anything and all the searching on the net has lead me to needing one module from SAMBA known as "vfs glusterfs", which has Samba talking directly to GlusterFS, removing Fuse from the middle.
