Hello,
I have been trying to upgrade my self-hosted engine from 4.3 to 4.4 but running into
issue while performing hosted-engine deploy.
Old hypervisor hosts are all running Centos 8 and old ovirt-engine is also running Centos
7.
I created a brand new baremental node running Centos 8, Kernel
4.18.0-240.15.1.el8_3.x86_64 and the following engine versions:
ovirt-hosted-engine-setup-2.4.9-1.el8.noarch
ovirt-hosted-engine-ha-2.4.6-1.el8.noarch
ovirt-engine-appliance-4.4-20210323171213.1.el8.x86_64
python3-ovirt-engine-sdk4-4.4.10-1.el8.x86_64
I have many VLANs in my environment. But on this host, I only have these network devices
set up (eth0 is the main network, eth1 for storage):
# nmcli con
NAME UUID TYPE DEVICE
ovirtmgmt 02f64861-d992-4e56-8cec-da1906bac09f bridge ovirtmgmt
Did you create ovirtmgmt manually, or let the deploy script create it?
System eth1 bd9e565f-bdc3-4e43-bbd3-5875b9d7fed7 ethernet eth1
virbr0 78e6875d-70f6-4c89-89dd-180dbb9250b1 bridge virbr0
eth0 743b0e26-aae7-44b8-9215-3754a537e90b ethernet eth0
vnet0 bcfead6d-c5b6-4428-9f89-41589735be02 tun vnet0
When I run hosted-engine --deploy --restore-from-file=backup_050321.bck, it hangs after
showing:
[ INFO ] TASK [ovirt.ovirt.engine_setup : Copy yum configuration file]
[ INFO ] changed: [localhost -> ovirt.safari.apple.com]
[ INFO ] TASK [ovirt.ovirt.engine_setup : Set 'best' to false]
[ INFO ] changed: [localhost -> ovirt.safari.apple.com]
[ INFO ] TASK [ovirt.ovirt.engine_setup : Update all packages]
You can disable this "Update all packages" by passing e.g.:
hosted-engine --deploy --ansible-extra-vars=he_offline_deployment=true
virsh shows the VM is in paused state:
# virsh list
Id Name State
----------------------------------
1 HostedEngineLocal paused
Any idea what made it become paused? Please check relevant logs (e.g.
/var/log/messages, /var/log/libvirt/qemu/*, /var/log/vdsm/*).
I was able to ssh onto the VM until that point.
You mean, until it became paused? Or also after that?
Do I need to set up all the network connection for all the VLANs before running the
deploy script?
In principle you should do nothing - just tell the process which NIC
to use for ovirtmgmt, and it will configure ovirtmgmt for you. All the
other network configuration you can/should do from inside the engine
admin ui. If you have other networks marked "required", the deployment
process will fail trying to add the host to the engine (because it
can't know which NICs/VLANs should be used for which networks) and
will pause, waiting for you to remove some lock file, letting you fix
stuff manually. See also: https://bugzilla.redhat.com/1893385 .
And how about engine storage domain? I have a new NFS mount ready but it did not ask me
about which storage domain to use. Will it ask in later stage?
Yes, storage is handled (also asked about) in a later stage, after the
engine is up and the host added to it.. This is a change from <= 4.2,
and was done so that we can use the engine (and vdsm) for this,
instead of duplicating their functionality in the deploy code.
Good luck and best regards,
