Ok.

The iod is performing a test during startup to see if it can in fact store
files in the directory that you have specified for it.  It is failing that
test, saying that it doesn't have permission to write.

You should look at the file /etc/iod.conf.  It may be empty; that's ok.
If there is not a datadir specified, the iod is trying to write into
/pvfs_data.

By default the iod changes its user id to "nobody" before running as a
security precaution.  In order for it to write to this directory then,
the user "nobody" must be able to write to it.  The best way to accomplish
this is to:

chown nobody <dir>
chmod 700 <dir>

This should fix this problem.
