[pgpool-general: 1567] Re: Online Recovery failed with unknown reason

[Kong Man]

I agreed that the debug mode does not help at all.  The problem could be due to various reasons.  One gotcha I had was, despite a well-established password-less SSH setup, if you haven't made the hostname/IP recognized as a known host, SSH would prompt and pgpool_recovery simply gives out 'ERROR:  pgpool_recovery failed' wihtout any additional message.

Try 'ssh se032c-94-31' and see if you get a prompt like the following.  If so, simply answer yes to get the symbolic name on the ~/.ssh/known_hosts file and try your pgpool_recovery one more time.

I hope this leads you to something, if it does not directly address your issue.

Thanks,

The authenticity of host '10.89.94.31 (10.89.94.31)' can't be established.

Are you sure you want to continue connecting (yes/no)?
