psycopg2.InternalError: bfz_nothing_write_ex write failed with (errno 28) No space left on device (compress_nothing.c:48) (seg1 slice1 db6:40001 pid=18228) (cdbdisp.c:1489)

I am using Greenplum with postgresql.
My version is 2.0.8.

I am trying to export some data into CSV file.
but there is enough space. (the data not in GB, hardly ~500MB).

here is my output of df -h

/dev/mapper/vg0-root 50G 38G 9.7G 80% / tmpfs 6.0G 0 6.0G 0% /lib/init/rw
varrun 6.0G 164K 6.0G 1% /var/run
varlock 6.0G 0 6.0G 0% /var/lock
udev 6.0G 156K 6.0G 1% /dev
tmpfs 6.0G 60K 6.0G 1% /dev/shm
/dev/sda1 487M 25M 437M 6% /boot /dev/mapper/vg0-tmp 497G 304G 168G 65% /var /dev/mapper/vg0-home 50G 33G 15G 69% /home

I am running it from home directory of the current user.

We cannot upgrade to latest version.
