Hi,
I deployed a multisite in order to sync data from a mimic cluster zone
to a nautilus cluster zone. The data sync well at present. However,
I check the cluster status and I find something strange. The data in my
new cluster seems larger than that in old ones. The data is far from full
synced while the space used is nearly the same. Does that normal?
