I tried to upgrade Mysql db from V2.0 to 2.9.80 using onedb upgrade -v command for updating db to support Opennebula 3. But ran in into issues described below
Does it need some more mysql component or some fix in onedb upgrade process ?


a.       OS :  Suse 11Sp1

b.      Mysql : Server version: 5.0.67 SUSE MySQL RPM

c.       Installed mysql components rpm -qa|grep mysql

Following issues were encountered:

1.       Following mysql gem install does not resolve all issues to run upgrade, needed to add gem sequel.

gem install mysql2-0.3.7.gem

gem install mysql-2.8.1.gem

./onedb  upgrade -v
/usr/lib64/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load -- sequel (LoadError)
        from /usr/lib64/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:31:in `require'
        from /srv/cloud/lib/ruby/onedb/onedb_backend.rb:18
        from /srv/cloud/lib/ruby/onedb/onedb.rb:18:in `require'
        from /srv/cloud/lib/ruby/onedb/onedb.rb:18
        from ./onedb:39:in `require'
        from ./onedb:39

gem install sequel-3.27.0.gem
Successfully installed sequel-3.27.0
1 gem installed
Installing ri documentation for sequel-3.27.0...

2.       During upgrade it refers to function count which does not exist.

./onedb  upgrade -v
Version read:
2.0 : Could not read any previous db_versioning data, assuming it is an OpenNebula 2.0 or 2.2 DB.

MySQL dump stored in /srv/cloud/var/mysql_localhost_opennebula.sql
Use 'onedb restore' or restore the DB using the mysql command:
mysql -u user -h server -P port db_name < backup_file
  > Running migrator /srv/cloud/lib/ruby/onedb/2.0_to_2.9.80.rb
Mysql::Error: FUNCTION opennebula.COUNT does not exist
