Hi all,
As we know, snapshot is a lightweight resource in librbd and we
doesn't have any statistic informations about it. But it causes some
problems to the cloud management.
We can't measure the size of snapshot, different snapshot will occur
different space. So we don't have way to estimate the resource usage
of user.
Maybe we can have a counter to record space usage when volumn created.
What do you mean with space usage? Cluster wide or pool usage?
When creating snapshot, the counter is freeze and store as the size of
snapshot. New counter will assign to zero for the volume.
Any feedback is appreciate!
