Indeed in case of ovirt-node-ng (or RHV-H for RHV) the update is only one 1Gb sized package containing the new image, but for plain CentOS Stream / CentOS (or RH EL 8 hosts for RHV) it can contain a hundred of packages and so a hundred of transactions vs one.

You are correct. It was implemented this way taking in consideration the
output when checking for updates on RHVH hosts.
This implementation is indeed going to be changed, so that upgrade will
become faster

For sure. This is always true. In my case part of the update is updating
the host from 8.3 to 8.4, so many packages involved.
And my observation is that it seems as if the process updates all the
packages one by one as subsequent commands, with an unneeded long time in
my opinion.
Each time it seems it goes through transaction test and so on...
Very very suboptimal if it is true and confirmed.
>From an ansible point of view it seems that it happens something like this
- name: ensure a list of packages installed
yum:
name: "{{ item }}"
state: latest
loop: "{{ packages }}"
instead of
- name: ensure a list of packages installed
yum:
name: "{{ packages }}"
state: latest
Where {{ packages }} is a pre-computed (probably in a previous step) list
of packages to be updated.

Hi Gianluca, Upgrade host time depends on the upgrading that needs to be done As for your second question, we updated ansible only if there was another package which required a new version of it, and we have used a different (temporarily created) yum.conf file which had the setting best=False, so yes, this behavior is currently expected, (and will be changed as we're going to allow updating ansible package for el8 hosts too) Hope this helps, Dana On Tue, Jun 8, 2021 at 12:28 PM Gianluca Cecchi wrote: > On Tue, Jun 8, 2021 at 11:15 AM Gianluca Cecchi > wrote: > >> Hello, >> I have a 4.4.5 environment that I'm upgrading to 4.4.6. >> >> I'm upgrading plain CentOS hosts from the GUI. >> They are in 4.4.5, so in particular CentOS 8.3 and as part of the upgrade >> they have to be put to 8.4. >> >> In the past I used "yum update" on the host but now it seems it is not >> the correct way. >> >> But the ansible part related to package updates seems to be very slow. >> It gives the impression that it is doing it one by one and not as a whole >> when you run "yum update" >> Now it is about 30 minutes that the update is going on and my internet >> speed is for sure very high. >> >> In messages of host I see every single line suche this ones: >> >> Jun 8 11:09:30 ov300 python3[3031815]: ansible-dnf Invoked with >> name=['rsyslog-relp.x86_64'] state=latest lock_timeout=300 >> conf_file=/tmp/yum.conf allow_downgrade=False autoremove=False bugfix=False >> disable_gpg_check=False disable_plugin=[] disablerepo=[] >> download_only=False enable_plugin=[] enablerepo=[] exclude=[] installroot=/ >> install_repoquery=True install_weak_deps=True security=False >> skip_broken=False update_cache=False update_only=False validate_certs=True >> disable_excludes=None download_dir=None list=None releasever=None >> Jun 8 11:09:32 ov300 python3[3031828]: ansible-dnf Invoked with >> name=['runc.x86_64'] state=latest lock_timeout=300 conf_file=/tmp/yum.conf >> allow_downgrade=False autoremove=False bugfix=False disable_gpg_check=False >> disable_plugin=[] disablerepo=[] download_only=False enable_plugin=[] >> enablerepo=[] exclude=[] installroot=/ install_repoquery=True >> install_weak_deps=True security=False skip_broken=False update_cache=False >> update_only=False validate_certs=True disable_excludes=None >> download_dir=None list=None releasever=None >> >> Any clarification? >> >> Thanks, >> Gianluca >> > > BTW the update had a duration of 33 minutes (I selected to not reboot the > host): > Jun 8, 2021, 10:40:35 AM Host ov300 upgrade was started (User: > tekka@mydomain). > Jun 8, 2021, 11:13:13 AM Host ov300 upgrade was completed successfully. > > At the end if I open a terminal I see: > > [root@ov300 ~]# rpm -q ansible > ansible-2.9.16-2.el8.noarch > [root@ov300 ~]# > > and > > [root@ov300 ~]# yum update > Last metadata expiration check: 0:39:50 ago on Tue 08 Jun 2021 10:41:09 AM > CEST. > Dependencies resolved. > > === > Package Architecture Version > RepositorySize > > === > Upgrading: > ansible noarch 2.9.21-2.el8 > ovirt-4.4-centos-ovirt44 17 M > > Transaction Summary > > === > Upgrade 1 Package > > Total download size: 17 M > Is this ok [y/N]: > Operation aborted. > [root@ov300 ~]# > > Is it expected? > Currently in my yum.conf I have: > > [main] > gpgcheck=1 > installonly_limit=3 > clean_requirements_on_remove=True > best=True > skip_if_unavailable=False > > Gianluca > > > ___ > Users mailing list -- users@ovirt.org > To unsubscribe send an email to users-le...@ovirt.org > Privacy Statement: https://www.ovirt.org/privacy-policy.html > oVirt Code of Conduct: > https://www.ovirt.org/community/about/community-guidelines/ > List Archives: > https://lists.ovirt.org/archives/list/users@ovirt.org/message/4P6YORNJVZG67EQT5TTVGCKMGXL7VRY5/ > ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/4RWDZDO6AY34UOFW6DCDCGCXIRW544L5/
