Hmm there is a difference between the blocks used and the file size.
I would guess that some program had access_log open, thus
keeping a hold on the blocks even if the file is truncated etc.
by another process. lsof /var/log/httpd/access_log should tell
you if some process has it open, and restarting that processes
should free the blocks up?

Exporting filesystems over NFS

To export filesystem in NFS with read-only access and no root
write access, edit the /etc/exports file and add the following line:
/dir/to/export (ro,insecure,all_squash).

'man 5 exports' for other details

The `exportfs -r` command makes the /etc/exports command take affect
