Jonathan Ellis commented on CASSANDRA-10199:
--------------------------------------------
Pushed to https://github.com/jbellis/cassandra/tree/10199, also a fix to avoid
huge mmap requests on 32-bit JVMs.
Is it worth trying to get fancy and detecting that commitlog has its own volume
and can get 100% of the space instead of 1/4?
> Warn on tiny disks instead of failing startup

> Fix For: 2.2.x

>
> m3.medium instances only have 4 GB disk space. We allocate 8 GB to commitlog
> by default.
> We should (1) cap CL to 1/4 of disk space and (2) warn when a tiny disk is
> seen.
