Hi all,

I'm glad to add glusterfs community.

I have a glusterfs cluster:

Nodes: 4

System: Centos7.1

Glusterfs: 3.8.9

Each Node:

CPU: 48 core

Mem: 128GB

Disk: 1*4T

There is one Distributed Replicated volume. There are ~160 k8s pods as clients connecting to glusterfs. But, the memory of  glusterfsd process is too high, gradually increase to 100G every node.

Then, I reboot the glusterfsd process. But the memory increase during approximate a week.

How can I debug the problem?

Hi,

Please take statedumps at intervals (a minimum of 2 at intervals of an hour) of a brick process for which you see the memory increasing and send them to us.  [1] describes how to take statedumps.

Regards,

Nithya
