[Fedora-directory-users] big searches dont return anything

[George Holbert]

Is it possible for DB corruption to be replicated?
In other words, if a master replica's DB goes corrupt, how likely is that to 
corrupt the DB on the consumers (if at all)?
Thanks,

Unfortunately that's something of an AI problem :(
There is some code in the server that can compare the
results of an indexed vs an unindexed execution of the same
query (used in the past to debug query optimizations). Someone
could develop that into a kind of index inconsistency tool.
All out corruption (someone writes random c**p over the
database pages _will_ be detected). It sounds like you had
some inconsistency between the primary and secondary
indices. I'm not sure how that could have happened
(it shouldn't).
