Notes

• notes as i've installed the system

• Accessing the nodes via ssh

# access the nodes, do this from the boot node: 
sudo su - 
(password)
dev ssh 
ssh <IP> # ip from the dashboard, access the private address of the nodes

• Reinstall a system without a full reboot

# on the boot node and as root
# edit the conf file 
vi /mnt/flash/conf/pentos.conf.used 
# then :
dev reinit

• Check status via CLI

# on boot node 
[root@boot-172-16-0-2 ~]# piston-dev.py cluster-info 
{u'control': {u'state': u'initialize:wait-for-nodes'},
 u'hosts': {u'172.16.1.3': {u'blessed': False,
                            u'context': {},
                            u'diskdata': None,

• Force reinstall

# create the file destroy-data on the USB root 
# or on the boot node: 
touch /mnt/usb1/destroy-data

• Problems with IPMI

# this is the command piston will use on the IPMI module - test out on the boot node to diagnose IPMI issues
[root@boot-192-168-0-2 ~]# ipmi-chassis -u admin -p admin -D LAN_2_0 -h 192.168.1.3 --get-status
ipmi-chassis: connection timeout
