[Gluster-users] Linux (ls -l) command pauses/slow on GlusterFS mounts

[Deepak Naidu]

Before we can try physical we wanted POC on VM.

Just a note the VMs are decently powerful 18cpus, 10gig NIC, 45GB Ram 1TB SSD drives. This is per node spec.

I don't see the ls -l command hanging when I try to list the files from the gluster-node VMs itself So the question.

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.
