OK my understanding is that with preallocated disks the performance with and without shard will be the same. In any case, please attach the volume profile[1], so we can see what else is slowing things down. -Krutika [1] - https://gluster.readthedocs.io/en/latest/Administrator%20Guide/Monitoring%20Workload/#running-glusterfs-volume-profile-command On Tue, Sep 5, 2017 at 2:32 PM, Abi Askushi

Hi Krutika, I already have a preallocated disk on VM. Now I am checking performance with dd on the hypervisors which have the gluster volume configured. I tried also several values of shard-block-size and I keep getting the same low values on write performance. Enabling client-io-threads also did not have any affect. The version of gluster I am using is glusterfs 3.8.12 built on May 11 2017

Help please- I am running 3.3.1 on Centos using a 10GB network. I get reasonable write speeds, although I think they could be faster. But my read speeds are REALLY slow. Executive summary: On gluster client- Writes average about 700-800MB/s Reads average about 70-80MB/s On server- Writes average about 1-1.5GB/s Reads average about 2-3GB/s Any thoughts? Here are some additional details:

I'm having a hard time trying to get a gluster volume up and running. I have setup other gluster volumes on other systems without much problems but this one is killing me. The gluster vol was created with the command: gluster volume create mariadb_gluster_volume laeft-dccdb01p:/export/mariadb/brick I had to lower frame-timeout since the system would become unresponsive until the frame failed

Hi Kashif, Thank you for your feedback! Do you have some data on the nature of performance improvement observed with 3.11 in the new setup? Adding Raghavendra and Poornima for validation of configuration and help with identifying why certain files disappeared from the mount point after enabling readdir-optimize.
