Can you check the cluster op version via:<br>
gluster volume get all cluster.op-version<br>
And the max version:<br>
gluster volume get all cluster.max-op-version<br>
<br>
<br>
If you restart the client (umount and then mount) , do you have the same memory usage?<br>
In your case the client is 5.10 , so you can try to update it to 5.11 (if the Gluster Cluster is on 5.11 or higher) and monitor it closely.<br>

Hi Strahil,<br>
Thanks for taking out time to help me.<br>
<br>
This is not a hyperconverged setup. We have 7 nodes with 2 bricks on each node. Total 14 node distributed setup.<br>
The host on which i saw the increased RAM is a client with glusterfs client version 5.10.<br>

We assumed that this config parameter indicates the amount of RAM that will be used on the client machine (i.e. upto 8 GB of RAM to be used for data caching at clients).
