Possible data loss

[dormando]

Uhh. Weird?

Do you have a lot of rows in file_to_replicate or file_to_delete or 
file_to_delete_later? It could be working through those?

Are you running a fsck?

If you connect to the trackers and run !watch are they spewing any 
errors? Double check your domain classes have the correct mindevcount?

Try strace'ing mogstored? :\

I'd just strace everything I can get my hands on at this point and watch 
for files being deleted, then backtrace. Are both of your trackers 
running mogilefsd v2 now?
