I've done a little research on this, but haven't the time to actually work out a fix.

It seems like slonik gets stuck because it is waiting for one of the slon daemons to quit or restart successfully. This has always been an issue for me, and I haven't been able to successfully get FAILOVER to execute.

The setup of 3 nodes (node 1 is master, node 2 is a slave that replicates the
master, and node 3 is another slave that replicates node 2). The
corresponding subscribe commands are:

subscribe set (id = 1, provider = 1, receiver = 2, forward = yes);
subscribe set (id = 1, provider = 2, receiver = 3, forward = yes);

At the point, everything is ok.

From node 2 (slave) machine, issue the following command:

failover (id = 1, backup node = 2);

slonik seems to be stuck (don't get the OS prompt for more than 15 minutes.
after printing out the following message:
<stdin>:8: NOTICE: failedNode: set 1 has no other direct receivers - move
now
<stdin>:8: NOTICE: failedNode: set 1 has no other direct receivers - move
now


Is this failover scenario in this configuration possible ? Any idea why the
slonik gets stuck ?

Thank you,
Tham
