Yes you can do this. You can set the maximum size of each file device by
configuring the "Volume default capacity" field of the device before
labelling it. So you can set the capacity of each device to slightly over
one third of the file system size so as to fully utilise the filesystem's
capacity. If all three devices become full the third one will fill at a
slightly lower capacity due to the filesystem becoming full.

No, it just works.
