Multi-Master Replication Problems

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

 



I'd love to know how your RUV could be missing.  I wonder if whatever 
problem left you with mismatched generation ID still persists, it seemed 
odd that happened after a network outage.  If the RUV entry was missing 
that would explain it, that's where the generation ID of the local data 
is stored.

Did you get replication running again?  Do your masters have updates 
that need to be merged?  If they're in sync or are only diverged by 
testing-related updates, I would try...
back up my two masters, for potential restore or future investigation 
(db2bak)
export one master to LDIF without -r (db2ldif)
import that LDIF into the same master (ldif2db)
perform the search for the RUV entry to make sure its created this time 
after the import completes (ldapsearch for the magic 
nsuniqueid=ffffffff-ffffffff-ffffffff-ffffffff entry)
initialize the other master, either via online initialization or LDIF 
with -r (db2ldif -r)

And if you can determine how you ended up in the state where the RUV is 
missing, post at bugzilla.redhat.com
