Are these directories writable?

ls -la /data1/grassdata/metro100/PERMANENT/.tmp
and
ls -la /data1/grassdata/metro100/PERMANENT/.tmp/caddis.appl-ecosys.com/

There is an easy debugging option integrated:

# switch on
g.gisenv set="DEBUG=1"
d.mon wx0
--> what are the messages?

# switch off
g.gisenv set="DEBUG=0"
