Hey there,

Basically, you're being affected by the self-healing features of the
replication translator.  From the GlusterFS FAQ:

Q:  What about deletion self/auto healing?

A:  With auto healing or self healing only file creation is healed. If
a brick is missing because of a disk crash re-creation of files is ok
but if it's a temporary network problem synchronizing deletion is

In other words, when that downed node comes back up, the healing
system sees that it has data that its partner lacks.  Giving the
benefit of the doubt that it's better to have an extra file laying
around than to suffer the possibility that the file should not have
been deleted, the healer errs on the side of caution and replicates
the file.

That said, the replication translator is not really meant to implement
a true RAID1 mirroring scheme, but rather to emulate the good bits of
such a scheme.  At least, that's my understanding thereof.
