Yes, no and maybe but it will involve pain.
A quick google came up with the following from a BSD mailing list.
Different OS but similar principle:

Yes. Delete some files.
Then, when you have it cleared up temporarily (deleting files is
only a brief temporary fix), back the file system up somewhere and
remake it. In the newfs command, use bytes, block-size and frag-size
arguments to force it to create more inodes in the filesystem and
then restore the backup. Possibly just setting bytes=2 will be
enough to cover it, but you may also need to set block-size=8192
and frag-size=1024 (which is kind of small).
If you run out of inodes, it tends to mean you are creating a lot
of small files. This can happen with some utilities that create
a new file for each piece of data. But, the default values for
bytes, block-size and frag-size usually provide plenty of inodes
for most things. So, maybe some job you are running is overdoing
creating small files for some reason or you have a database designed
less efficiently or something.
By using a smaller block and fragment size, you get more inodes, but
you make reading and writing large files less efficient. Of course,
if you have a hoard of small files, that isn't important. In fact,
if the file system if full of small files, then it is less efficient
to have large block and fragment sizes.
