[Sheepdog] Small sheepdog howto

[PCextreme B.V. - Wido den Hollander]

Hi,

root at wido-desktop:~# corosync-cfgtool -s
Printing ring status.
Local node ID 537307328
RING ID 0
	id	= 192.168.6.32
	status	= ring 0 active with no faults
root at wido-desktop:~# 

And my shepherd gives back:

root at wido-desktop:~# shepherd info -t dog
  Idx	Node id (FNV-1a)    - Host:Port
--------------------------------------------------
  0	4c212f70289e9103 - 127.0.1.1:7000
  1	4c212f70289e9103 - 127.0.1.1:7000
* 2	4c212f70289e9103 - 127.0.1.1:7000
  3	4c212f70289e9103 - 127.0.1.1:7000
  4	4c212f70289e9103 - 127.0.1.1:7000
root at wido-desktop:~#

I've attached my "corosync.conf" where i have auth turned on and a
synced "authkey" file on all the nodes.

Tried without auth turned on, but gave the same result.

root at wido-desktop:~# corosync-cfgtool -s
Printing ring status.
Local node ID 537307328
RING ID 0
	id	= 192.168.6.32
	status	= ring 0 active with no faults
root at wido-desktop:~# corosync-cfgtool -a 268871872
192.168.6.16
root at wido-desktop:~# 

It seems that my desktop knows the IP of "sheepdog01":

root at sheepdog01:~# corosync-cfgtool -s
Printing ring status.
Local node ID 268871872
RING ID 0
	id	= 192.168.6.16
