[Gluster-users] Linux (ls -l) command pauses/slow on GlusterFS mounts
Anyone who has seen the issue in their env ? -- Deepak -----Original Message----- From: gluster-users-bounces at gluster.org [mailto:gluster-users-bounces at gluster.org] On Behalf Of Deepak Naidu Sent: Tuesday, August 09, 2016 9:14 PM To: gluster-users at gluster.org Subject: [Gluster-users] Linux (ls -l) command pauses/slow on GlusterFS mounts Greetings, I have 3node GlusterFS on VM for POC each node has 2x bricks of 200GB. Regardless of what type of volume I create when listing files under directory using ls command the GlusterFS mount hangs pauses for few seconds. This is same if there're 2-5 19gb file each or 2gb file each. There are less than 10 files under the GlusterFS mount. I am using NFS-Ganesha for NFS server with GlusterFS and the Linux client is mounted using GlusterFS fuse mount with direct-io enabled. GlusterFS version 3.8(latest) Any insight is appreciated. -- Deepak ----------------------------------------------------------------------------------- This email message is for the sole use of the intended recipient(s) and may contain confidential information.

Can you try on a physical setup to see if the same behavior is observed? -Vijay
