Hello,
When a Ceph block device is created with a given size, does Ceph allocate all that space right away or is that allocated as the user starts storing the data?
I want to know if we can over provision the Ceph cluster. For example, if we have a cluster with 10G available space, am I allowed to create only 10, 1G volumes? Or can I over provision and assume that each volume is going to be used only up to 50% and allow creation of 20 1G volumes?
Thanks,
Shridhar
