Eric Evans commented on CASSANDRA-14793:
----------------------------------------
Awesome; I'd been meaning to open this very ticket.
I had planned to suggest what [~krummas] did, that it be possible to put
{{system}} in a different data directory. At least if this were possible,
{{system}} could be put on a RAID. And, at least in our environments, if the
expectation is that you can survive a single device failure, then the OS is
likely already on RAID-1 or similar.
Of course, if the tables in {{system}} could be regenerated, that would be
better still but I'm not sure what that looks like complexity-wise versus
pinning it.
