Rather than full reinstall, Enroll Certificate action (just next to
Reinstall in the menu) should be faster and sufficient.  You still need
to set the host to maintenance before being allowed to do it.

[ovirt-users] Re: Moving HostedEngine

[Strahil]

It is highly 'super duper' not recommended to do that.
Also, consider using thinLVM (requirement for gluster snapshots) for a brick of 
the separate gluster volume.

I'm using the 3rd partirion of my OS SSD to host my gluster's volume and I have 
no issues so far.

[ovirt-users] Re: Certificate of host is invalid

[Strahil]

Hi ,

You can try with:
1. Set the host in maintenance
2. From Install dropdown , select 'reinstall' and then configure the necessary 
info +  whether you would like  to use the host as Host for the HostedEngine VM.

Once the reinstall (of Ovirt software)  is OK, the node will be activated 
automatically.

[ovirt-users] Re: spice connection error

[Strahil]

As far as I know , the engine plays a role as a proxy during the establishment 
of the connection.
Check that you can reach both engine and the host from your system.

For the same reason, I use noVNC - as you just need  a single port to the 
engine in addition to the rest of the settings.

[ovirt-users] Re: Engine deployment last step.... Can anyone help ?

[Strahil]

Hi Rob,

Can you check the gluster's volume ?

gluster volume status engine
gluster volume heal engine info summary

Still, this is strange that the firewall is having such differences.

Fastest way to sync that node to the settings from the other is to:
1. Backup /etc/firewalld
2. Remove /etc/firewalld
3. Copy /etc/firewalld from another node (either scp or rsync wil do)
4. Restart the firewalld daemon
5. Make a test firewalld reload

[ovirt-users] Re: Cannot obtain information from export domain

[Strahil]

Hi can you describe your actions?
Usually the export is like this:
1. You make a backup of the VM
2. You migrate the disks to the export storage domain
3. You shut down the VM
4. Set the storage domain in maintenance  and then detach it from the oVirt
5. You atttach it to the new oVirt
6. Once the domain is active - click on import VM tab and import all VMs 
(defining the cluster you want them to be running on)
7. Power up VM and then migrate the disks to the permanent storage.

[ovirt-users] Re: Moving HostedEngine

[Joseph Goldman]

So I can't host OTHER VM's on this gluster volume? If its already a 
running GLuser for other VMs i can't now re-reploy HE in that gluster 
volume?

As a fall back option (although I've never had to use it) I have a 
backup engine VM running completely outside of oVIrt (ESXi host in my 
case). Then if the hosted_engine deploy fails for any reason you can 
restore onto the backup vm as a temp solution while you work through 
the hosted engine deploy issues.


A few things that come to mind: -

* You will need a dedicated gluster volume for hosted_storage and it 
needs to be replica+arbiter.
* Make sure you put the cluster in global maint mode before performing 
the engine backup, I recall having issues with the restore when I

[ovirt-users] HostedEngine Deployment fails on AMD EPYC 7402P 4.3.7

[Ralf Schenk]

Hello,

This week I tried to deploy Hosted Engine on Ovirt-Node-NG 4.3.7 based Host.

At the time the locally deployed Engine ist copied to hosted-storage (in
my case NFS) and deployment tries to start the Engine (via
ovirt-ha-agent) this fails.

QUEMU Log (/var/log/libvirt/qemu/HostedEngine.log) only shows
"2019-11-27 16:17:16.833+: shutting down, reason=failed".

Researching the cause is: The built Libvirt VM XML includes the feature
"virt-ssbd" as requirement, which is simly not there.

[ovirt-users] Re: Moving HostedEngine

[Alan G]

I've had to do this a couple of times and always ended up with a working system 
in the end.



As a fall back option (although I've never had to use it) I have a backup 
engine VM running completely outside of oVIrt (ESXi host in my case). Then if 
the hosted_engine deploy fails for any reason you can restore onto the backup 
vm as a temp solution while you work through the hosted engine deploy issues.



A few things that come to mind: -



* You will need a dedicated gluster volume for hosted_storage and it needs to 
be replica+arbiter.

* Make sure you put the cluster in global maint mode before performing the 
engine backup, I recall having issues with the restore when I didn't do that.

* Migrate all other VMs off the host running Engine before doing the backup. 
This will be the host you will restore onto.

[ovirt-users] Certificate of host is invalid

[Jon bae]

Hello everybody,
since last update to 4.3.7 I get this error message:

Certificate of host *host.name * is invalid. The
certificate doesn't contain valid subject alternative name, please enroll
new certificate for the host.

Have you an idea of how I can fix that?

Regards
Jonathan

[ovirt-users] Moving HostedEngine

[Joseph Goldman]

Hi List,

 In one of my installs, I set up the first storage domain (and where 
the HostedEngine is) on a bigger NFS NAS - since then I have created a 
Gluster volume that spans the 3 hosts and I'm putting a few VM's in 
there for higher reliability (as SAN is single point of failure) namely 
I'd like to put HostedEngine in there so it stays up no matter what and 
can help report if issues occur (network issue to NAS, NAS dies etc etc)


 Looking through other posts and documentation, there's no real way to 
move the HostedEngine storage, is this correct? The solution I've seen 
is to backup the hosted engine DB, blow it away, and re-deploy it from 
the .backup file configuring it to the new storage domain in the deploy 
script - is this the only process? How likely is this to fail? Is it 
likely that all VM's and settings will be picked straight back up and 
continue to operate like normal? I dont have a test setup to play around 
with atm so just trying to gauge confidence in such a solution.


Thanks,
Joe

[ovirt-users] spice connection error

[kim . kargaard]

Hi,

When trying to connect from a remote network on the spice console to a VM, I 
get the following error:

(remote-viewer:80195): virt-viewer-WARNING **: 11:05:22.322: Channel error: 
Could not connect to proxy server xx.xx.xx.xx: Socket I/O timed out

I found that the display is set to the management network and not the VM 
networkn in the cluster logical network. However, when I try to set the other 
vlan to be the display network, I get the following error:

Error while executing action: Cannot edit Network. IP address has to be set for 
the NIC that bears a role network. Network: student-vlan100, Nic: p2p1.100 on 
host node3 violates that rule.

I am not sure what this means. Any ideas?

Kind regards

Kim

[ovirt-users] oVirt nodes not responding

[Tim Herrmann]

Hi everyone,

we have an oVirt-Cluster with 5 nodes and 3 of them provide the storage
with GlusterFS and replica 3.
The cluster is running 87 VMs and has 9TB storage where 4TB is in use.
The version of the oVirt-Engine is 4.1.8.2 and GlusterFS is 3.8.15.
The servers are running in a HP bladecenter and are connected with 10GBit
to each other.

Actually we have some problems that all ovirt nodes periodically won't
respond in the cluster with the following error messages in the oVirt
webinterface:

VDSM glustervirt05 command GetGlusterVolumeHealInfoVDS failed: Message
timeout which can be caused by communication issues
Host glustervirt05 is not responding. It will stay in Connecting state for
a grace period of 68 seconds and after that an attempt to fence the host
will be issued.
Host glustervirt05 does not enforce SELinux. Current status: PERMISSIVE
Executing power management status on Host glustervirt05 using Proxy Host
glustervirt02 and Fence Agent ilo4:xxx.xxx.xxx.xxx.
Manually synced the storage devices from host glustervirt05
Status of host glustervirt05 was set to Up.


In the vdsm logfile I can find the following message:
2019-11-26 11:18:22,909+0100 WARN  (vdsm.Scheduler) [Executor] Worker
blocked:  timeout=60, duration=180
at 0x316a6d0> task#=2859802 at 0x1b70dd0> (executor:351)


And I figured out, that the gluster heal info command takes very long:
[root@glustervirt01 ~]# time gluster volume heal data info
Brick glustervirt01:/gluster/data/brick1
Status: Connected
Number of entries: 0

Brick glustervirt02:/gluster/data/brick1
Status: Connected
Number of entries: 0

Brick glustervirt03:/gluster/data/brick2
Status: Connected
Number of entries: 0


real 3m3.626s
user 0m0.593s
sys 0m0.559s


A strange behavier is also that there is one virtual machine (a postgresql
database) which stops running unexpectedly every one or two days ...
The only thing that has been changed on the vm in the least past was a
resize of the disk.
VM replication-zabbix is down with error. Exit message: Lost connection
with qemu process.

And when we add or delete a larger disk with approximately 100GB in
glusterfs, the glusterfs cluster freaks out won't respond anymore.
This also results in paused VMs ...


Has anyone an idea what could cause such problems?
