Filenames on 'server' jobs to shared filesystems

I'm currently using fio to simulate user reads and writes to a NAS
service, and am testing the performance of different shared filesystems
(NFS, Samba, Glusterfs etc).

In order to properly load the box I'm using a pool of clients to connect
to the fs (fio --server) and then launching the same job on multiple
clients. (fio --client=a --client=b job.fio)

The resulting jobs on the different servers all seem to use the same
file - the filename seems to be <name>.<thread>.<fileno> - in this case
'job.1.0':

[global]
directory=/mnt/gluster
rw=randrw
size=10M
ioengine=libaio

[job]


Is there any way to have the server include some personal identifier
(such as hostname) in the filename so that there isn't this conflict?

Thanks,

Matthew
