> > Yes @GutoVeronezi, there are global settings to (1) notify users, or (2)
disable new volume allocation, if allocated capacity or actual used capacity
reaches a threshold.
> > The thresholds are around 75% or 85%, so users have enough time to get
more storage or clean the storage.

> ok, I thought only overprovisioned threshold would be signalled. I don't
know of an extra guard on the actual threshold , but then again we would expect
operators to do their due diligence. Sorry for the over-paranoia.
no worries @DaanHoogland
I think this is a frequently asked question for many users.
