Question about moving mailboxes between partitions

[Egoitz Aurrekoetxea]

Good morning,

We are running Cyrus 2.3.18 very happily. We have noticed that Cyrus mailbox partition (and config partition) is starting to pass the 70% of used space. So we have decided to add a new disk to the server 
in order to create a new Cyrus mailbox partition. Later we’ll move some of the big or some more of the littleler mailboxes to this new mailbox  partition.

Have been doing some checks and have noticed of two things : 

- The directory of the mailbox in the source partition is not being removed… it stays totally empty but there…
- In the slave replica (I’m using Cyrus replication) the mailbox is not being moved automatically from partition one… to partition two.. the mailbox destination (the new added mailbox partition)

I wanted to ask, are these two behaviors considered normal? just for knowing if perhaps the code could be doing something wrong…. And mainly talking about the second question about the 
renm and replication because I’m seeing it does automatically in the slave relocate the mailbox in the second partition… perhaps this is normal too… but IIRC Cyrus replication died if there weren’t 
the same partitions in the master and the slave…. with the same names… or does it just do that for being able to do cm commands only??.

Best regards,
