Ekaterina Dimitrova commented on CASSANDRA-17150:
-------------------------------------------------
Solid patch as usual, it just took me some time to wrap up my mind as I see
this work first time.
I left small questions&comments.
I am thinking it is good to verify with [~jasonstack] the new approach you took
in regards to the calculations. Maybe it was considered during the initial
discussions and he has something to add? Or maybe it's just me making noise. :)
1 thing I noticed is we will hit warnings faster. Probably it is more accurate
but I am also wondering about recommendations for users in order not to corner
themselves.
We need also NEWS.txt entry.

> Add guardrails for disk usage establishing soft/hard limits on the percentage
> of used disk space. For example:
> {code}
> # Warning threshold to warn when local disk usage exceeds threshold. Valid
> values: (1, 100]
> # Defaults to -1 to disable.
> # disk_usage_percentage_warn_threshold: -1
> # Failure threshold to reject write requests if replica disk usage exceeds
> threshold. Valid values: (1, 100]
> # Defaults to -1 to disable.
> # disk_usage_percentage_failure_threshold: -1
