I install patched PostgreSQL 9.4.1 with BDR 0.9.0, and set up a BDR group of
2 linux hosts, each has 4 replicated databases. Global sequence is enabled
(whose configuration is added in postgresql.conf).
When I insert new records into any of 4 databases in the first host (created
via bdr.bdr_group_create), all get replicated to the second host (created
via bdr.bdr_group_join).
In reverse, when I insert new records into any of 4 databases in the second
host, data are only successfully replicated to 3 out of 4 databases. From
the database where failures occur, I observe this error:
# select nextval('table_id_seq');
ERROR: global sequence public.table_id_seq is not initialized yet
HINT: All nodes must agree before the sequence is usable. Try again soon.
Check all nodes are up if the condition persists.
Here are current BDR status:
[first host]# select node_name, node_status from bdr.bdr_nodes;
node_name | node_status
--------------+-------------
first | r
second | i
[second host]# # select node_name, node_status from bdr.bdr_nodes;
node_name | node_status
--------------+-------------
first | r
second | r
I'd like to ask for suggestions on how to troubleshoot and recover from this
situation.
Thank you.
