Hi,

The following steps has been done:

/etc/yum.repos.d/opennebula.repo

in: baseurl=https://downloads.opennebula.org/repo/5.10/CentOS/7/x86_64

# yum update
Put back mysql section from oned.conf.rpmsave to oned.conf
$ onedb upgrade -v -S localhost -u oneadmin -p '!Password' -d opennebula

And now I have to failed to start services:

$ systemctl list-units --state=failed

Hello @gray380,

Please could you run /usr/lib/one/mads/one_hm write INIT and share the output?

gray380 · November 27, 2019, 9:09am

Hello Christian,

Pretty empty:

[root@one-srv-01 sadm]# /usr/lib/one/mads/one_hm
[root@one-srv-01 sadm]# /usr/lib/one/mads/one_hm INIT
[root@one-srv-01 sadm]#

BTW /etc/one/hm/hmrc is empty (contains only comments)

Can I switch off the Hook Execution Service in some way as workaround?

vholer · November 27, 2019, 11:07am

Hello @gray380,

do you have SELinux enabled? If yes, can you pls check for any related denied actions?

grep -i deni /var/log/audit/audit.log

If there is nothing suspicious, can you please attach list of all your packages and their versions?

rpm -qa

(ideally, also please do a verification of the installed files via rpm -Va).

If still nothing strange, can you please fallback to installation of Ruby dependencies via install_gems as described here? http://docs.opennebula.org/5.10/deployment/opennebula_installation/frontend_installation.html#step-4-ruby-runtime-installation-optional

first drop symlink unlink /usr/share/one/gems
then continue with /usr/share/one/install_gems

Thank you,
Vlastimil

gray380 · November 27, 2019, 11:36am

Hi,

SELinux disabled:

[root@one-srv-01 sadm]# getenforce
Disabled

installed_packages.txt (30.7 KB)

The following commands executed:

# rpm -Va
# test -L /usr/share/one/gems && unlink /usr/share/one/gems
# /usr/share/one/install_gems

Services restarted but still failed.
And the new warning message has apppeared in the system log:

Nov 27 13:42:53 one-srv-01 mysqld[1586]: 2019-11-27 13:42:53 1706 [Warning] Aborted connection 1706 to db: 'opennebula' user: 'oneadmin' host: 'localhost' (Got an error reading communication packets)

Meanwile I’ve downgraded to 5.8.x

Okay, I’ve tried upgrade again with help of the following link: Upgrading from OpenNebula 5.8.x

And faced the same issue:

For some reason I’ve failed to downgrade like at first attempt.
It says db mismatch:

Thu Dec  5 16:21:43 2019 [Z0][ONE][I]: Log level:3 [0=ERROR,1=WARNING,2=INFO,3=DEBUG]
Thu Dec  5 16:21:43 2019 [Z0][ONE][I]: Support for xmlrpc-c > 1.31: yes

Thu Dec  5 16:21:43 2019 [Z0][ONE][E]: Database version mismatch ( local_db_versioning). Installed OpenNebula 5.8.5 needs DB version '5.8.0', and existing DB version is '5.10.0'.
Thu Dec  5 16:21:43 2019 [Z0][ONE][E]: Use onedb to upgrade DB.

But onedb itself says version is okay:

[oneadmin@one-srv-01 ~]$ onedb upgrade -v -S localhost -u oneadmin -d opennebula
Version read:
Shared tables 5.6.0 : OpenNebula 5.8.0 daemon bootstrap
Local tables  5.8.0 : OpenNebula 5.8.0 daemon bootstrap

MySQL dump stored in /var/lib/one/mysql_localhost_opennebula_2019-12-5_16:20:46.sql
Use 'onedb restore' or restore the DB using the mysql command:
mysql -u user -h server -P port db_name < backup_file


>>> Running migrators for shared tables
Database already uses version 5.6.0

>>> Running migrators for local tables
Database already uses version 5.8.0

gray380 · December 5, 2019, 3:22pm

Okay, I’ve fixed DB issue (droped opennebula database from the mysql and restore it with onedb).
So opennebula srvice is up and running.
At least for now

But what is wrong with the upgrade?
