Replication Craziness

[mischa z]

Hi, I will try to answer this since Russ is not in the office at the moment.

How big/small are these files?


  4MB in average

Anything interesting/noisy in the
> mogilefsd error logs?


Looks all good. Occasional there are timeouts:
" :: [monitor(11947)] Timeout contacting machine 10.0.10.24 for dev 47:
took 2.00 seconds out of 2 allowed"

Does the mogilefs-server "make test" pass for you?


"All tests successful, 3 tests skipped."
On the nodes the test skips the Db tests and it complains about not finding
the mogadm executable. Nothing crucial I guess.

Which MySQL server version?


 mysql> SELECT version();
+------------+
| version()  |
+------------+
| 5.0.37-log |
+------------+

Cheers,
Mischa
