Data goes to *all* PGs uniformly.
Max_avail is limited by the available space on the most full OSD --
you should pay close attention to those and make sure they are moving
in the right direction (decreasing!)
Another point -- IMHO you should aim to get all PGs active+clean
before you add yet another batch of new disks. While there are PGs
backfilling, your osdmaps are accumulating on the mons and osds --
this itself will start to use a lot of space, and active+clean is the
only way to trim the old maps.

Currently the max_avail lingers around 13TB and I hope, that the data will go to other PGs
than the ones that are currently on filled OSDs.
