Subject Re: Repair doesn't work after upgrading to 0.8.1
Date Fri, 01 Jul 2011 08:16:40 GMT
To make it clear what the problem is, this is not a repair problem. This is
a gossip problem. Gossip is reporting that the remote node is a 0.7 node
and repair is just saying "I cannot use that node because repair has changed
and the 0.7 node will not know how to answer me correctly", which is the
correct behavior if the node happens to be a 0.7 node.

Hence, I'm kind of baffled that dropping a keyspace and recreating it fixed
anything. Unless as part of "removed the keyspace", you've deleted the
system tables, in which case that could have triggered something.
