Hi Adrian,

thank you very much for your response.

I ran the "VACUUM ANALYZE" command on the master node.

Regarding log messages.

Here is the contents of the log (excluding connections/disconnections):

Assuming the below is from the replica database.


2016-02-22 02:30:08 GMT 24616  LOG:  recovery has paused

So what happened to cause the above?

I am not seeing anything below that indicates the recovery started again.

2016-02-22 02:30:08 GMT 24616  HINT:  Execute pg_xlog_replay_resume() to
continue.

What does the log from the master show?



Best regards,
Fredrik Huitfeldt

    HI All,

    i would really appreciate any help I can get on this issue.

    basically, a pg_basebackup + streaming attach, led to a database
    that we
    could not read from afterwards.


From original post:

http://www.postgresql.org/message-id/1456919678340.31300.116900@webmail2

"The issue remained until we ran a full vacuum analyze on the cluster."

Which cluster was that, the master or the slave?

"I have logfiles from the incident, but I cannot see anything out of
the ordinary (despite having a fair amount of experience investigating
postgresql logs)."


Can we see the section before and after ERROR?


    Beset regards,
    Fredrik

    PS please advise if this is better posted on another list.
