I have a Kubernetes cluster with 10 nodes ( 32Core , 128Gi ram , 128Gi SSD for host OS )
And now I am using c-stor ( replication 3 ) ( in HDD hard raid 5 )
When one of the nodes fails and I want to move the replicas
This operation is very slow
For example, a 200 GB replica takes 15-20 hours to upgrade from 2 to 3 replicas
For example in this example
To improve performance I made some changes according to this document

After editing the CVCs, the situation improved, but the speed is still low
