Subject [jira] [Commented] (CASSANDRA-2116) Separate out filesystem errors from generic IOErrors

Why would that be more useful?

In some implementations (not talking about KeysIndex) it's not just IO that might go wrong.
I don't want to make people choose between wrapping the real exception in IOE or RTE or swallowing
everything.
There is at least one other implementation - in DSE, probably other ones, so it's not a completely
made up issue.

> We throw IOErrors everywhere today in the codebase. We should separate out specific errors
such as (reading, writing) from filesystem into FSReadError and FSWriteError. This makes it
possible in the next ticket to allow certain failure modes (kill the server if reads or writes
fail to disk).
