Hello,
we have deployed ceph cluster with 4 monitors and 22 osd's. We are using
only rbd's. All VM's on KVM have specified monitors in the same order.
One of monitors (the first on the list in vm disk specification -
ceph35) has more load than others and the performance of cluster is
poor. How can we fix this problem. Here is 'ceph -s' output:
