Yes it happens.  Depends on what you specify when you specify tape
capacity.
I found that it would seldom go beyond 100% if you are using client
compression, but will regularly go well beyond 100% if there is no
client compression and there are compressible files (think standard
ASCII files versus binary type files).

You can keep it from doing this by re-stating the drive capacity, but I
like to state the drive capacity as the stated uncompressed capacity of
the drive and anything over that is pure gravy.

The volume, even if over 100%, will stay in filling status until the
volume reaches its end of volume.  It is possible to be full even if 89%
full (or at least something less than 100%) if the end of volume is
reached.  It is possible to see this if you specify the volume capacity
to be larger than the uncompressed capacity, or if there is some media.
