We do use MySQL replication, but at the moment there's only one tracker
running on this system, so it shouldn't make any difference. There are 4
nodes currently in the system, each with 6 devices on. At the moment
we're batch importing small files (images) at a rate of about 2GB/hour.
The only other unusual thing is that we're using a separate instance of
lighttpd on each node with a separate getport. I might try and change
that to making mogstored start lighttpd.

My two very general euro cents, but this has to be triggered by something
in your local configuration - something that most people aren't doing, so
I guess it would be cool to know a little bit more, about things like
mysql
setup (cluster, replication), what are the actual classes and devcounts,
what replication policy you're using (custom?), storage node server
(webdav
or mogstored) and setup (devs, amount of free space), how you inject
files
and when (ie. add a graph line with the nb. of files)...

I've just set up a brand new MogileFS cluster - the tracker is
2.17 and
passed all the tests - and it's definitely exhibiting an
overreplication
issue:

(overreplicated files are file.devcount > class.mindevcount,
underreplicated are where the reverse is true. Files to replicate
is the
size of file_to_replicate)
Any clues?
