====================== ALLOCATED NODES ======================
JARVICENAE27: slots=1 max_slots=0 slots_inuse=0 state=UP
10.3.0.176: slots=1 max_slots=0 slots_inuse=0 state=UNKNOWN
Also, I am not able to ssh to other machine from one machine in chroot
environment. Can that be a problem ?
Thanks
Rahul
