<div> my problem :</div>
<div> On oVirt and Gluster hyper-converged environment (
which is glusterfs and ovirt on one host ,and there are three
hosts ,glusterfs volume is replication 3 abrit 1 )</div>
<div><br>
</div>
<div> storage domain use glusterfs volume which is used
glusterfs mount or nfs mount , vms running , happenned vm
memory top to 97%~99% suddenly , this current high </div>
<div><br>
</div>
<div>probability on vms which on the same host , but this time ,
vm'memory not used 97%~99% actually ,and memory down to the
actual value latterly , all above problem can see by <br>

Is sharding enabled on the gluster volume?<br>
Which version of glusterfs are you using?<br>
<br>
Is the CPU usage on the servers consistently high? <br>
