[Sheepdog] Small sheepdog howto

[PCextreme B.V. - Wido den Hollander]

Hi,

There is no "corosync-cpgtool" under Ubuntu 9.10.

I'm using the version shipped with Ubuntu 9.10, in my case this is
corosync 1.0.

After changing my "hosts" file where it only contains a line with
"127.0.0.1" and localhost and my hostname i am getting different errors
when starting collie:

Jan 26 11:33:56 wido-desktop collie: Target daemon logger with pid=9909
started!
Jan 26 11:33:57 wido-desktop collie: worker_routine(175) started this
thread 0
Jan 26 11:33:57 wido-desktop collie: last message repeated 2 times
Jan 26 11:33:57 wido-desktop collie: create_cluster(756) Failed to join
the sheepdog group, try again
Jan 26 11:33:57 wido-desktop collie: worker_routine(175) started this
thread 0
Jan 26 11:33:58 wido-desktop collie: create_cluster(756) Failed to join
the sheepdog group, try again

Now all my 4 nodes are giving this error.

After turning off encryption in corosync and changing the /etc/hosts
file to something like:

127.0.0.1	localhost
192.168.6.16	sheepdog01


My sheepdog is working:

  Idx	Node id (FNV-1a)    - Host:Port
--------------------------------------------------
  0	3207b6b8f585c0b6 - 192.168.6.32:7000
* 1	4d90ac8be7d92a5c - 192.168.6.10:7000
  2	8cf20c574f9095db - 192.168.6.17:7000
  3	a9158087adfa4d46 - 192.168.6.16:7000

So the hostname of the machine should map to the "external" IP of the
machine.
