Re: inconsistent PG -> unfound objects on an erasure coded system

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The pgs are not actually inconsistent (that is, I think that all of
the real objects are present and healthy).  I think each of those pgs
has one of these duplicate pairs confusing scrub (and also pg removal
-- hence your ENOTEMPTY bug).  Once we figure out what's going on,
you'll have to clean them up manually.  Do not repair any of these.  I
suggest that you simply disable scrub and ignore the inconsistent flag
until we have an idea of what is going on.
