[Pgpool-general] online recovery fails on HPUX

Fri Sep 2 07:17:29 UTC 2011

If you already have an sshkey defined and it's the same user on both
servers then. I am not sure what could be causing the failure but
according to your log its an ssh auth issue.

Have you tried running a telnet test to the port to check that is
listening...

Sorry, I didn't get you..  Actually, both the server instances and the
pgpool running on the same host..  Could this be an issue of loopback?

SSh trust must be created on both server for all the accounts involved
in the recovery process.

I would add the ssh-keys the the user for pgpool and try again.

I can see the following lines in /tmp/pgpool.log:

What does your pgpool.conf say about logging:

# Logging directory

logdir = '/var/log'

I see following two lines when the pcp_recovery_node is fired..  Also, I
cannot find recovery.log, but recovery.conf is present in standby
cluster directory.. 

....

2011-08-31 05:49:22 LOG:   pid 20430: starting recovering node 1
2011-08-31 05:49:22 ERROR: pid 20430: start_recover: could not connect
master node.
....

The pg_hba.conf has the following entry:

# "local" is for Unix domain socket connections only
local   all             all                                     trust
# IPv4 local connections:

# IPv6 local connections:
host    all             all             ::1/128                 trust

Hi,

I'm using Postgres Plus Advanced Server on HP-UX 11.31 and found that
the online recovery does not work here. 

pgPool version is 3.0.3-4

$pcp_recovery_node  -d 20 localhost 9898 edb edb 1
DEBUG: send: tos="R", len=41
DEBUG: recv: tos="r", len=21, data=AuthenticationOK
DEBUG: send: tos="D", len=6
DEBUG: recv: tos="e", len=20, data=recovery failed
DEBUG: command failed. reason=recovery failed
BackendError
DEBUG: send: tos="X", len=4

I can see the following in the log:
....
LOG:  incomplete startup packet
LOG:  connection failed during start up processing: user= database=
....

Moreover, I do not see pgpool_recovery_node statement in the log, so
wondering if it is really getting executed. I have tried my scripts on
Linux and it worked all fine. So, there is no issue with the pgpool.conf
or my basebackup and other files.. Could this be an issue of HPUX?

Thanks.
