Hi, We're using a 3-node setup where GlusterFS is running as both a client and a server with a fuse mount-point. We tried to change the performance.parallel-readdir setting to on for a volume, but after that the load on all 3 nodes skyrocketed due to the glusterd process and we saw CPU soft lockup errors in the console. I had to completely bring down/reboot all 3 nodes and disable the
