[ovirt-users] Re: 20+ Fresh Installs Failing in 20+ days [newbie & frustrated]

Hi Henni,
your issue is just here:
2020-10-16 11:20:59,445+0200 DEBUG var changed: host "localhost" var
"hostname_resolution_output" type "" value: "{
"changed": true,

"stdout_lines": [

]
}"

but then...

2020-10-16 12:15:43,079+0200 DEBUG var changed: host "localhost" var
"he_vm_ip_addr" type "" value: ""156.38.192.226""

"he_cloud_init_domain_name" type "" value: ""xyz.co.za""

So,
your host is named node01.xyz.co.za and it resolves to 156.38.192.226,
then you are trying to create a VM named engine01.xyz.co.za and you are
trying to configure it with a static set IPv4 address which is
still 156.38.192.226.
This is enough to explain all the subsequent networking issues.

Please try again using two distinct IP addresses for the node and the
engine VM.

ciao,
Simone

The interactive installer is not passing it and the default behaviour is to
omit the parameter if the variable is unset to let the engine wisely detect
and choose.
https://github.com/oVirt/ovirt-ansible-hosted-engine-setup/blob/master/tasks/bootstrap_local_vm/05_add_host.yml#L62
So yes, you can simply inject a custom value

It is not clear in my opinion what does it mean the sentence: "cluster CPU

Read this as "as first HE host". This parameter can be useful if you plan
to add older hosts in the future and you prefer to start from the beginning
with a CPU type for the cluster that's less required than what can be
detected from the first one.
I tend to think that in the past the set of CPU features was monotonically
increasing between a CPU family and a newer one. This is less easy now with
all the different security patches.

As expected,
in my opinion now the point is just about understanding why the engine
detected your host with the wrong CPU features set.

To be fully honest, as you can see in
https://github.com/oVirt/ovirt-ansible-hosted-engine-setup/blob/master/README.md#L46
, we already have a variable (he_cluster_cpu_type) to force a cluster CPU
type from the ansible role but I don't think is exposed in the interactive
installer.

No, the user is not allowed to force a specific CPU type for the cluster:
hosted-engine-setup process will simply register the first host into the
Default cluster and the engine will detect the CPU type and configure the
cluster according to the detected CPU.
I tend to think that this is a bug in the code that chooses the CPU
type for the cluster according to what the host reports.

This is probably the side effect of a previous error so self._listener is
None but i'm pretty sure that something failed before trying to initialize
it.
Can you please share the whole log file?

Maybe in the past you destroyed/removed my mistake the default libvirt

The storage traffic allocation over multiple subnets is implicitly set by
name resolution and routing rules.

Please use two distinct hostnames for each host: the first one should
resolve only as an address on the management network and the second one as
an address on the storage network.

In the cockpit wizard for the hyperconverged deployment you will be
prompted twice about the name of the three hosts: on the first tab (named
'Hosts') use the three host-names that resolves on the storage network.
On the second tab ('Additional Hosts') please use the hostnames that are
going to be resolved over the management network.

Yes, it's that one.

AFAIK it's not going to fail the whole deployment because we added an
ignore over that kind of errors.
AFAIK it's not systematic.

Normally in oVirt you are going to have a central manager, the engine, plus
N virtualization hosts running VMs storage on external storage.
Using it with a single host with no external storage is a kind of
degenerate case.

I'd still suggest the single node hyper-converged hosted-engine deployment
that's is designed exactly for your use case.

You are going to install oVirt node on your bare metal machine: oVirt node
is a kind of minimal Centos based OS deployment for oVirt purposes.
hosted-engine deployment will create a first VM there based on a ready to
use appliance and oVirt engine will be executed there.
The storage will be exposed by the host itself via gluster.

The easiest deployment path is:
1. install oVirt node on your bare metal server from an ISO:
https://resources.ovirt.org/pub/ovirt-4.3/iso/ovirt-node-ng-installer/4.3.6-2019092614/el7/ovirt-node-ng-installer-4.3.6-2019092614.el7.iso
2. connect to its cockpit UI: on https://host_address:9090/
3. run single host hyper-converged depoyment from hosted-engine tab from
there

Hi Adrian,
you want to configure your engine VM to get an IP address from DHCP, right?

Are you sure that the value of he_ansible_host_name exactly matches the
address of your first host as used in your inventory file?

I'd suggest to deploy it as a single host hyperconverged gluster deployment.
You can easily do it connecting to its cockpit web ui.

Hi,
oVirt provides VM Pools:
https://www.ovirt.org/documentation/admin-guide/chap-Pools.html

but the VMs in pool are designed to be stateless and so, on that user case,
the user specific data should stored on an external (not on the VM disk)
storage area like an NFS or SMB/CIFS share mounted inside the VM at user
login time.

Probably you can achieve something closer to your initial idea relying on
oVirt-CinderLib integration over a capable SAN or a Ceph storage.
https://ovirt.org/develop/release-management/features/storage/cinderlib-integration.html
Please be aware that in 4.3 cinder-lib integration is still a
"tech-preview" grade feature and the design of the whole solution will
probably require a relevant integration/configuration effort on your side
to correctly achieve copy-on-write behaviour on storage side.

The hosted-engine needs to communicate with the hosts for management
operations; this happens over a logical network called management network.
The hosts have to communicate with the storage, you can create an
additional logical network with different addressing for that; the engine
doesn't need any direct access to the storage which is always mediated by
the hosts.

For simplicity, if feasible in your environment, I'd suggest to create an
additional storage dedicated logical network on your hosts instead of
playing with manual injected firewall rules over the management one.

Sorry for the delay, I missed this thread.

>From ovirt-hosted-engine-setup you can configure the iSCSI storage domain,
exposed by a single iSCSI target, to be accessed over multiple portals in a
single portal group.
Once you have a running engine you can eventually complete the
configuration creating an iSCSI bond from there.
Follow this guide for that:
https://ovirt.org/documentation/admin-guide/chap-Storage.html#configuring-iscsi-multipathing

Let's now focus on the first part.
On your SAN you should create more than one iSCSI portal.
Then you should group them in a single iSCSI target portal group.
You iSCSI target should be configured to be exposed over the whole iSCSI
target portal group.
Then you have to create a LUN for the hosted-engine storage domain and
associate it with that iSCSI target.

Now, on hosted-engine-setup (via CLI or via cokpit) you should enter the IP
address or one of the iSCSI portals (and eventually one username/password
couple for the iSCSI discovery).
The iSCSI discovery process will report back your iSCSI targets and the
address of other iSCSI portals in the same iSCSI target portal group; each
of them will be a path so if you have more than one iSCSI portal in a
single iSCSI target portal group you will have multipath.

Next step is choosing one of the listed iSCSI targets, then
hosted-engine-setup will list the LUNs there and you will be able to choose
one of them to be used for the hosted-engine storage domain.

The flow is:
1. set hosted-engine global maintenance mode
2. choose one of the existing hosts and set it to maintenance mode from the
engine
3. take a backup of your current engine with engine-backup
4. copy the backup file to your host
5. on the host in maintenance mode run:
hosted-engine --deploy --restore-from-file=backup.tar.gz
6. at the end you will have a new engine VM created from your backup file,
the previous hosted-engine storage domain will be still visible (although
renamed) so that you can eventually migrate additional VMs created there by
mistake; at the end you can remove it
7. one host at at time, set other hosted-engine hosts to maintenance mode
and choose reinstall being sure to choose to deploy hosted-engine
that's all.

The issue is on the size of the gluster volume not on the size of the
hosted-engine VM disk.
Please try extending the gluater volume.

Please try executing this on your engine VM:

oVirt VMs contains something like:

  http://ovirt.org/vm/tune/1.0; xmlns:ovirt-vm="
http://ovirt.org/vm/1.0;>

http://ovirt.org/vm/1.0;>
4.2

in the XML for libvirt so you are checking the wrong VM.

Can you please try to directly mount that NFS share on your host and ensure
that you can write there as VDSM user?
You can try something like:
  sudo -u vdsm mkdir test
but after that please clean up the directory.

Yes, there is an open bug tracked at https://bugzilla.redhat.com/1707225
<https://bugzilla.redhat.com/show_bug.cgi?id=1707225> about handling
cinderlib integration in the backup.
It's targeted for 4.3.6.

Honestly I don't see any workaround other than trying to manually backup
and restore the cinderlib DB.

[ovirt-users] Re: hosted engine not getting up

[Simone Tiraboschi]

The hosted-engine VM configuration is wrote by the engine on a special
volume called OVF_STORE.
According to the logs ovirt-ha-agent correctly extracted it:

Got vm.conf from OVF_STORE

Can you please check engine.log on your engine VM for errors there
generating the OVF_STORE?

It happens trying to deploy oVirt 4.2 with ansible 2.8.
We fixed it for oVirt 4.3 which is the stable release (4.3.4 as for today)
but never backported it to the older oVirt 4.2.
I'd strongly suggest to start with oVirt 4.3.z, if you really need oVirt
4.2 you can try downgrading ansible to 2.7.

Ok, the issue is here:
2019-06-17 13:50:04,014+0200 DEBUG otopi.plugins.otopi.dialog.human
dialog.__logString:204 DIALOG:SEND Please indicate a nic to
set ovirtmgmt bridge on: (team0, team0.13, team0.19) [team0.13]:
2019-06-17 13:50:14,978+0200 DEBUG otopi.plugins.otopi.dialog.human
dialog.__logString:204 DIALOG:RECEIVEteam0.19

oVirt doesn't support at all the teamed devices but just bonds, please see:
https://www.ovirt.org/documentation/admin-guide/chap-Logical_Networks.html#bonding-modes

Unfortunately ansible facts module as for
https://github.com/ansible/ansible/issues/43129 also fails discriminating a
teamed interface from a plain one and so you were able to select it.

We had an old bug about that:

but it's reported as fixed.

Can you please detail the exact version of ovirt-engine and vdsm you are

Hi,
it's this one: https://bugzilla.redhat.com/1692671
<https://bugzilla.redhat.com/show_bug.cgi?id=1692671>

adding gluster_features_fqdn_check: false to your inventory should be
enough to avoid it.
it's currently fixed as for:

That idea is going to work at LVM level inside the VM, but at the end the
hosted-engine VM is a VM so potentially taking a snapshot at VM level is a
better option.
Currently this is not working because the hosted-engine VM disk is
protected for split brains by a volume lease (VM leases weren't available
when we started hosted-engine) and this inhibits snapshots and so live
storage migration and so on.
We already have an open RFE  to implement it for 4.4:

Thanks,
we are trying to execute
  SELECT SUM(pg_database_size(datname)) As dbms_size FROM pg_database

but your postgres instance fails on that query.

Can you please try executing on the engine VM:
  sudo -u postgres scl enable rh-postgresql95 -- psql -d engine -c
"SELECT SUM(pg_database_size(datname)) As dbms_size FROM pg_database"

and if it fail share the output of:
  ls -lZ /var/opt/rh/rh-postgresql95/lib/pgsql/data/base/13699369/1259_fsm
(or the file where it fails on).

You have to configure all the VMs as HA enabling a VM lease on that.
The engine will take care to restart them.

VM leases are also wrote to the relevant storage domain and so they are
going to be in sync if you are correctly syncing the storage on the two
sites.

HA mechanism for the engine VM is provided by ovirt-ha-agent service
running on all the hosted-engine configured hosts (at least a couple on
each site).
The hosted-engine configured hosts communicate via a whiteboard wrote on
the hosted-engine storage domain so, if the storage devices on the two
sites are in sync (it requires latency < 7ms), all the hosted-engine host
can also see the status on the other site and eventually take over.
The volume lease is there to enforce, at storage level, that only one host
at a time is able to run the engine VM (regardless of the site where is it
since also the lock is in sync).

You cannot create a VM lease for the hosted-engine VM because the
hosted-engine VM is always already protected by a volume lease.

Honestly I'm not aware of that, can you please provide more details?
where does it happen? on the host or inside the engine virtual machine?
is it going to happen before starting the engine virtual machine or during
host-deploy process when the engine is going to configure the host?

Do you mean inside ovirt-engine-appliance image?
If on host side instead, ovirt-host rpm should instead already require all
(but the ovirt-engine-appliance which is about 1 GB) the rpms needed for
the deployment.

hosted-engine-setup is already designed to work also in disconnected mode
assuming that all the required rpms have been installed upfront.
If it fails on that use case, and all the rpms are there, it's definitively
a bug.

Any changes to the engine VM configuration should trigger an immediate
refresh of the OVF_STORE volumes.
You can check engine.log for that.

A possible workaround is to try editing at the same time also a different
value such as the VM description.

Hi,
the engine VM has to talk with the hosts over the management network which
is always based on a linux bridge.
In addition to that, you can create one or more additional logical networks
for your VMs over OVN.


> There are some documentation of how to do ovn installation?
>

All the OVN components are automatically installed, you have just to create
a new logical network choosing "Create on external network provider"
selecting ovirt-provider-ovn there.
You can configure the subnet panel if needed.
When you are going to create a new VM or edit an existing one, you will be
able to choose the OVN based logical network.

Hi,
fine till here, then
- copy the backup file on the host you are going to use for the restore
- run something like hosted-engine --deploy
--restore-from-file=/root/engine-backup.tar.gz
- when the tool will ask about HE storage domain, provide the details to
create a new empty one
- once done, connect to the engine, set host 2 into maintenance mode and
reinstall it from the engine choosing to redeploy hosted-engine
- do the same for host 3
- at the end the previous hosted-engine storage domain will be still
visible (but renamed) in the engine; eventually migrate out other VM disks
created there; once ready you can delete it

I's suggest to check engine.log on the bootstrap engine VM; unfortunately
engine error responses are not always that explicit.

OK, the issue on the host is just here:
MainThread::DEBUG::2016-10-10
11:18:34,169::brokerlink::282::ovirt_hosted_engine_ha.lib.brokerlink.BrokerLink::(_communicate)
Full response: success {"reason": "failed liveliness check", "health":
"bad", "vm": "up", "detail": "up"}
MainThread::DEBUG::2016-10-10
11:18:34,169::brokerlink::255::ovirt_hosted_engine_ha.lib.brokerlink.BrokerLink::(_checked_communicate)
Successful response from socket
MainThread::DEBUG::2016-10-10
11:18:34,170::brokerlink::151::ovirt_hosted_engine_ha.lib.brokerlink.BrokerLink::(get_monitor_status)
Success, status {"reason": "failed liveliness check", "health": "bad",
"vm": "up", "detail": "up"}

the engine VM goes up but the engine no and so after a certain amount of
time it tries again with a reboot.
We should definitively add a more explicit log entry there!

Now the point is just why your engine is not starting.

Currently ovirt-ha-agent is periodically reconnecting the hosted-engine
storage domain and checking its status. This is already on jsonrpc.
In 4.1 all the monitoring will be moved to jsonrpc.

I'm trying it right now.
Any other tests will be really appreciated.

The patch is pretty simply, you can apply that on the fly.
You have to shutdown ovirt-ha-broker and ovirt-ha-agent; then you could
directly edit
/usr/lib/python2.7/site-packages/api/vdsmapi.py
around line 97 changing from
loaded_schema = yaml.load(f)
to
loaded_schema = yaml.load(f, Loader=yaml.CLoader)
Please pay attention to keep exactly the same amount of initial spaces.

Then you can simply restart the HA agent and check.

You can use something like what is documented here:
https://bugzilla.redhat.com/show_bug.cgi?id=1366879#c23

Instead of fixing fhanswers.conf as in that script, you have to fix
broker.conf

[ovirt-users] Re: unable to upgrade from ovirt 3.6 to 4.0.4

[Simone Tiraboschi]

Hi Alon,
you just need the backup/restore backup procedure if you have to change the
OS of the server where you installed your engine.
It it was already at el7 you don't need that.

In every case the upgrade to 4.0 is requiring that all your cluster and all
your data center should be at 3.6 compatibility level before the upgrade.
>From the error you got, it seams that you still have something at 3.5.

I'd suggest to use the engine appliance also for this.
You can just say No when it asks about automatically running engine-setup.

In order to let the engine auto-import the new hosted-engine storage
domain, you have to remove the old one.
The same for the engine VM. Unfortunately you cannot do that from the
engine since they are somehow protected to avoid unintentional damages.
The easiest way is to remove them from the DB before running engine-setup.
I'm working on a helper utility to make it easiser:
https://gerrit.ovirt.org/#/c/64966/
I think I'll integrate it with engine-backup to simply do it with an
additional CLI flag.

Right, we can also integrate this step in the HE cleaning helper.

I strongly suggest to deploy them from the engine and not from CLI.
CLI deploy support for additional HE host is deprecated an it will be
removed in 4.1.

Yes, we are going to fix that too (

also https://bugzilla.redhat.com/show_bug.cgi?id=1376843 to be fixed.

hosted-engine-setup is, and sooner or later we'll have to migrate also the

The engine will automatically create it once the hosted-engine storage
domain and the engine VM are correctly been imported.

Yes, the issue was the lack of entropy.
haveged on a VM works but the quality of its entropy is still debated.
A better solution is to use the paravirtualized VirtIO RNG device.

We already have it on the first boot; we are working to ensure it's always
there also after the engine imported the engine VM:

No, this should be fine.

The issue is that periodically your gluster volume losses its server quorum
and become unavailable.
It happened more than once from your logs.

Can you please attach also gluster logs for that volume?

Yes, it's due to the fact that ovirt-ha-agent periodically reconnects over
json rpc and this is CPU intensive since the client has to parse the yaml
API specification each time it connects.
The issue is tracked here:
https://bugzilla.redhat.com/show_bug.cgi?id=1349829 - ovirt-ha-agent should
reuse json-rpc connections
but it depends on:
https://bugzilla.redhat.com/show_bug.cgi?id=1376843 - [RFE] Implement a
keep-alive with reconnect if needed logic for the python jsonrpc client

Thanks Jason,
I suspect that your issue is related to this:

and for some time your gluster volume has been working.

But then:

And at that point VDSM started complaining that the hosted-engine-storage
domain doesn't exist anymore:
Oct  4 19:02:30 dcasrv01 journal: ovirt-ha-agent
ovirt_hosted_engine_ha.lib.image.Image ERROR Error fetching volumes list:

Storage domain does not exist: (u'bbb70623-194a-46d2-a164-76a4876ecaaf',)

I see from the logs that the ovirt-ha-agent is trying to mount the
hosted-engine storage domain as:
/usr/bin/mount -t glusterfs -o backup-volfile-servers=dcastor02:dcastor03
dcastor01:engine /rhev/data-center/mnt/glusterSD/dcastor01:engine.

Pointing to dcastor01, dcastor02 and dcastor03 while your server is
dcasrv01.
But at the same time it seams that also dcasrv01 has local bricks for the
same engine volume.

So, is dcasrv01 just an alias fro dcastor01? if not you probably have some
issue with the configuration of your gluster volume.

In 4.3 we completely removed the support for 3.6 and 4.0 datacenter/cluster
levels as for:
https://bugzilla.redhat.com/1655115
<https://bugzilla.redhat.com/show_bug.cgi?id=1655115>

No way using 4.3 stuff (that's why we also removed --upgrade-appliance from
hosted-engine in 4.3).
Your only option now is to use 4.2 only repos with oVirt or RHV-H from 4.2
if on RHV.

We had a bug about that in the past:
https://bugzilla.redhat.com/1644748
<https://bugzilla.redhat.com/show_bug.cgi?id=1644748>
but it's reported as CLOSED CURRENTRELEASE.

Can I ask which versions of ovirt-hosted-engine-setup,
ovirt-ansible-hosted-engine-setup
and ovirt-engine-appliance are you using?

I see that you sent more than one email in the last days and in general all
the issue you are reporting are due to timeouts/race conditions.
Can you please provide some more info about your storage configuration?

Yes, please notice that now ovirt-hosted-engine-setup rpm depends on
ovirt-ansible-hosted-engine-setup
one which installs the role.
All the deployment logic is inside ovirt-ansible-hosted-engine-setup which
is packaged as an rpm while ovirt-hosted-engine-setup contains the CLI
interactive front-end.
If you need a fully unattended setup with no interactive validation I'd
suggest to simply consume the ansible role.

I tried reproducing this with oVirt node nested over KVM and everything
worked as expected for me.
Honestly I'm not hyper-v expert but I'd suggest to try changing something

It seems barely reproducible: maybe a race condition somewhere.
I know it can look a bit clumsy but I suggest to simply give it another try.

Other machines are not required to communicate with the engine during the
deployment so we are not routing 192.168.122.1/24 neither masquerading it
for NAT traversal.

Hi,
you can use OVEHOSTED_NETWORK/host_name

Please notice that now if you need a fully unassisted deployment you can
directly trigger ovirt.hosted_engine_setup ansible role.
You can find its documentation here:
https://github.com/oVirt/ovirt-ansible-hosted-engine-setup/blob/master/README.md

99% that folder was dirty (it already contained something) when you started
the deployment.
I can only suggest to clean that folder and start from scratch.

Good catch: the issue comes exactly form here!
Please see:
https://bugzilla.redhat.com/1694626

The issue happens when the user has two interfaces configured on the same
IP subnet, the default gateway is configured to be reached from one of the
two interfaces and the user chooses to create the management bridge on the
other one.
When the engine, adding the host, creates the management bridge it also
tries to configure the default gateway on the bridge and for some reason
this disrupt the external connectivity on the host and the the user is
going to loose it.

If you intend to use one interface for gluster and the other for the
management network I'd strongly suggest to use two distinct subnets having
the default gateway on the subnet you are going to use for the management
network.

If you want to use two interfaces for reliability reasons I'd strongly
suggest to create a bond of the two instead.

Please also notice that deploying a three host hyper-converged environment
over a single 1 gbps interface will be really penalizing in terms of
storage performances.
Each data has to be written on the host itself and on the two remote ones
so you are going to have 1000 mbps / 2 (external replicas ) / 8 (bit/bytes)
= a max of 62.5 MB/s sustained throughput shared between all the VMs and
this ignoring all the overheads.
In practice it will be much less ending in a barely usable environment.

I'd strongly suggest to move to a 10 gbps environment if possible, or to
bond a few 1 gbps nics for gluster.

You can check what you need with something like:
rpm -qf /usr/share/ovirt-engine/brands/ovirt.brand

OK, understood it comes from here:

oVirt doesn't supported teamed interfaces but only bridged one and I guess
that your 'team0' is a team and not a bond.

Unfortunately, due to an ansible issue, we are not able to automatically
identify team network devices:
https://github.com/ansible/ansible/issues/43129

I'd suggest to reconfigure team0 as bond0 (please take care that also the
name is relevant) and try again.
