Subject Re: Bootstrap question
Date Sun, 18 Jul 2010 19:01:27 GMT
Yeah, I tried all that already and it didn't seem to work, no new nodes
will bootstrap, which makes me think there's some saved state somewhere,
preventing a new node from bootstrapping.  I think maybe the Location
sstables?  Is it safe to nuke those on all hosts and restart everything?
(I just don't want to lose actual data).

Thanks for the ideas,

-Anthony
