Cannot access ovirt/rhv platform after upgrading.

pullium

Lpar2rrd running on an AIX 7.2tl3sp2 system.

We receive the following message when attempting to access ovirt/rhv platform.

We followed the reference document for installing Postgres Support. We can access the other platforms in the list.

Hi,

follow this to install necessary modules.

http://www.lpar2rrd.com/oVirt-Postgres-support.htm

pullium

We have already installed the perl-DBI, peril_DBi-Pg, and other suggested packages outlined in http://www.lpar2rrd.com/oVirt-Postgres-support.htm

Pavel

ok, it will be PERL5LIB issue only

cd /home/lpar2rrd/lpar2rrd

grep PERL5LIB= etc/lpar2rrd/cfg

pullium

Here are setting from etc/lpar2rrd.cfg file

# Path to RRDTool binary

  RRDTOOL=/usr/bin/rrdtool

# Perl binary

  PERL=/usr/bin/perl

# PERL=/opt/freeware/bin/perl

# Perl path for searching modules, it must containg path to RRDp.pm module, usually it is all discovered automatically

 PERL5LIB=/home/lpar2rrd/lpar2rrd/bin:/usr/opt/perl5/lib/5.20.1:/usr/opt/perl5/bin:/opt/freeware/lib/perl5/:/opt/freew

are/bin/perl:/home/lpar2rrd/lpar2rrd/lib:/home/lpar2rrd/lpar2rrd/vmware-lib

Pavel

put at the end of PERL5LIB in etc/lpar2rrd.cfg this path:

/opt/freeware/lib/perl5/vendor_perl/5.8.8/ppc-thread-multi

-->

 PERL5LIB=/home/lpar2rrd/lpar2rrd/bin:/usr/opt/perl5/lib/5.20.1:/usr/opt/perl5/bin:/opt/freeware/lib/perl5/:/opt/freeware/bin/perl:/home/lpar2rrd/lpar2rrd/lib:/home/lpar2rrd/lpar2rrd/vmware-lib:/opt/freeware/lib/perl5/vendor_perl/5.8.8/ppc-thread-multi

then try it again

Adding "/opt/freeware/lib/perl5/vendor_perl/5.8.8/ppc-thread-multi" at the end of my PERL5LIB introduces an additional error:

try exactly this setting:

  PERL=/opt/freeware/bin/perl
  PERL5LIB=/home/lpar2rrd/lpar2rrd/bin:/home/lpar2rrd/lpar2rrd/vmware-lib:/opt/freeware/lib/perl/5.8.8:/usr/opt/perl5/lib/site_perl/5.8.8/aix-thread-multi:/opt/freeware/lib/perl5/vendor_perl/5.8.8/ppc-thread-multi:/home/lpar2rrd/lpar2rrd/lib

  RRDTOOL=/usr/bin/rrdtool

however my example is with

/usr/bin/rrdtool -v
RRDtool 1.4.8  Copyright 1997-2013 by Tobias Oetiker <tobi@oetiker.ch>

AIX is not the best platform for resolving of such dependencies 

Linux require single install cmd which does everyhing and all is working then

pullium

Will try. That looks like our original configuration after the upgrade where ovirt/rhv was working but we could not ingest new data for AIX systems.

Pavel

Have you already have running oVirt in beta?

Check your old PERL5LIB setting in and try to use it

cd /home/lpar2rrd/lpar2rrd

grep PERL5LIB= B*/*/etc/lpar2rrd.cfg
