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. 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! -- Best Regards, Wheat -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
