Hello Doug,

WOW, a big thank you
yes everything works fine now
I can see the USB key with its usage percentage

I missed the 
pgrep devmon function&>/dev/null||/usr/bin/devmon&>/dev/null&


[root at NODE1420 ~]# pgrep devmon function&>/dev/null||/usr/bin/devmon&>/dev/null&
[1] 15804
[root at NODE1420 ~]# df
