Problem with SSH connection

Hello Team, 

I migrated the stor2rrd application from older RHEL 7.9 to 9.3.

All arrays such Dell/Hitachi/HPE woks properly.

I have a problem with connection to SVC/V7000, i've getting "connection closed" in error log and it's all :(

ERROR LOG:

"

Connection closed

Connection closed

Connection closed

Connection closed

Connection closed

Connection closed

Connection closed

"



Do you have any idea how i can debug what closing this connection?

 

stor2rrd version: 7.30

linux version: release 9.3 (Plow)

    Dear Pavel,

    I upgrade stor2rrd and i see this:

    Error: Can't locate object method "new" via package "Net::OpenSSH" at /stor2rrd/stor2rrd/bin/SVC.pm line 2045.

    Mon Jul 1 15:48:22 2024 - ERROR  - svcconfig.pl: ERROR: Unable to connect to xxx

     - Return code: 1

     - Return code: 1




    I've found other issue with lenovo v3700 and newer stor version and i was check perl version:


    =================

    [stor2rrd@xxx:stor2rrd stor2rrd]$ $PERL -MNet::OpenSSH -e 'print "Version: $Net::OpenSSH::VERSION\n"'

    Version: 0.80

    =================

    [stor2rrd@xxx:stor2rrd lib]$ more Xorux/Net/OpenSSH.pm

    package Xorux::Net::OpenSSH;


    our $VERSION = '0.83';


    use strict;

    use warnings;

    =================


    [stor2rrd@xxx:stor2rrd lib]$ more Net/OpenSSH.pm

    package Net::OpenSSH;


    our $VERSION = '0.80';


    use strict;

    use warnings;


    =================

    [stor2rrd@xxx:stor2rrd lib]$ perl -v


    This is perl 5, version 32, subversion 1 (v5.32.1) built for x86_64-linux-thread-multi

    (with 53 registered patches, see perl -V for more detail)

    The command lssystem works properly from error works properly. Other arrays works normally :)

    So i'm thinking there is a problem with perl. I can't send you logs, because our policy lock any uploading package outside organization :(



    Maybe you have any idea what i should check?

    Maybe there is a option to replace a openssh.pm lib in stor2rrd?

    Maybe it would be help?

  • Pavel
    Pavel

    remove this package: perl-Net-OpenSSH-0.82-3.el9.noarch

    hereis inclyded 0.80 perl-Net-OpenSSH in lpar2rrd lib.

    try connection test again

    Note a short problem description in the text field of the upload form.


    cd /home/stor2rrd/stor2rrd # or where is your STOR2RRD working dir


    tar cvhf logs.tar logs tmp/*txt


    gzip -9 logs.tar


    Send us logs.tar.gz via https://upload.stor2rrd.com

    Our security locs all zips/tar/gz/etc. ;(


    So thanks for trying to help me, i will try to found where is the problem. If i will find i will put to forum information :)


    Have a good day!

    Pavel

    are you at the latest stor2rrd version 7.90?

  • Dariusz
    Dariusz

    Yes. i downloaded from stor2rrd official web page - https://stor2rrd.com/download.php


    Maybe the old configuration is blocking, this instance have few years...

    it remember configuration from file ./etc/storage-list.cfg


    i will try to remove one array (all data) and then try to add like a fresh array :)

    Regards,

    Dariusz

    not necessary, just upgrade

    etc/storage-list.cfg is not being used
