Hi folks, I have been experimenting with oVirt cluster based on glusterfs for the past few days. (first-timer). The cluster is up and running and it consists of 4 nodes and has 4 replicas. When I try to deploy Windows Server VM I encounter the following issue: The disk of the VM has ok reading speed ( close to bare metal) but the writing speed is very slow. ( about 10 times slower than it is supposed to be). Can anyone give me any suggestion, please? Thanks in advance! Here are the settings of the glusterfs volume:
