How exactly did you add it?

What is "cluster"?
- the cluster inside the engine's DB (what you see in the admin UI)
- gluster cluster
- hosted-engine cluster (to do that, you should choose that option
when you add the host)

What do you mean in "always"? You can't use the web portal anymore at all?

[ovirt-users] [Help] The engine is not stable on HostedEngine with GlusterFS Herperverged deployment

[mengz . you]

Hi, 

I deployed a oVirt (4.3.10) cluster with HostedEngine and GlusterFS volumes 
(engine, vmstore, data), the glusterfs cluster on node1/node2/node3, and the 
engine vm can be running on those 3 nodes.  
Then I added a 4th nodes into cluster.  

But, when I operates on Eninge Web Portal, it's always reports 503 error, then 
I checked `hsoted-engine --vm-status`, see below:  

```
[root@vhost1 ~]# hosted-engine –vm-status

Then, wait a moment, can access web portal again, and check the hosts status, 
alway reports one or more hosts with label `unavaiable as HA score`, but it

And I found, sometimes the engine vm will migrated to another nodes whill this 
problem occur.  

So, seems the HostedEngine is not stable, always occur this problem, could you 
please help me with this ?  Thanks!

[ovirt-users] ova import

[eevans]

I am running Ovirt 4.3 and exported machines as ova which includes disks. When 
I re import them. the disks are thin provisioned and the vm will not boot. 
Any idea how to get the import to  preallocate disks?  I have vms that will not 
boot.
It states no bootable disk is available.
It seems the virt2vm isn't working correctly.
ANy help would be appreciated.

[ovirt-users] Re: New Management VLAN for hyperconverged cluster

[David White via Users]

I still haven't been able to resurrect the 1st host, so I've spent some time 
trying to get the hosted engine stable. I would welcome input on how to fix the 
problematic host so that it can be accessible again.

As per my original email, this all started when I tried to change the 
management vlan. I honestly cannot remember what I did (if anything) to the 
actual hosts when this all started, but my troubleshooting steps today have 
been to try to fiddle with the vlan settings and 
/etc/sysconfig/network-scripts/ files on the problematic host to switch from 
the original vlan (1) to the new vlan (10).

Until then, I'm troubleshooting why the hosted engine isn't really working, 
since the other two hosts are operational.

The hosted engine is "running" -- I can access and navigate around the oVirt 
Manager.
However, it appears that all of the storage domains are down, and all of the 
hosts are "NonOperational". I was, however, able to put two of the hosts into 
Maintenance Mode, including the problematic 1st host.

This is what I see on the 2nd host:

[root@cha2-storage network-scripts]# gluster peer statusNumber of Peers: 2

Hostname: cha1-storage.mgt.example.com
Uuid: 348de1f3-5efe-4e0c-b58e-9cf48071e8e1

Uuid: 0563c3e8-237d-4409-a09a-ec51719b0da6
State: Peer in Cluster (Connected)

[ovirt-users] New Management VLAN for hyperconverged cluster

[David White via Users]

I'm working on setting up my environment prior to production, and have run into 
an issue.

I got most things configured, but due to a limitation on one of my switches, I 
decided to change the management vlan that the hosts communicate on. Over the 
course of changing that vlan, I wound up resetting my router to default 
settings.

I have the router operational again, and I also have 1 of my switches 
operational.
Now, I'm trying to bring the oVirt cluster back online.This is oVirt 4.5 
running on RHEL 8.3.

The old vlan is 1, and the new vlan is 10.

Currently, hosts 2 & 3 are accessible over the new vlan, and can ping each 
other.
I'm able to ssh to both hosts, and when I run "gluster peer status", I see that 
they are connected to each other.

However, host 1 is not accessible from anything. I can't ping it, and it cannot 
get out.

As part of my troubleshooting, I've done the following:
>From the host console, I ran `nmcli connection delete` to delete the old vlan 
>(VLAN 1).
I moved the /etc/sysconfig/network-scripts/interface.1 file to interface.10, 
and edited the file accordingly to make sure the vlan and device settings are 
set to 10 instead of 1, and I rebooted the host.

The engine seems to be running, but I don't understand why.
>From each of the hosts that are working (host 2 and host 3), I ran 
>"hosted-engine --check-liveliness" and both hosts indicate that the engine is 
>NOT running.

Yet the engine loads in a web browser, and I'm able to log into 
/ovirt-engine/webadmin/.
The engine thinks that all 3 hosts is nonresponsive. See screenshot below:

[Screenshot from 2021-04-07 17-33-48.png]

What I'm really looking for help with is to get the first host back online.
Once it is healthy and gluster is healthy, I feel confident I can get the 
engine operational again.

What else should I look for on this host?

oVirt supports integration with OKD with KubeVirt. I've no video to 
show it for oVIrt (yet) but you can see it here for RHV / OCP: 
https://www.youtube.com/watch?v=MMEaZAxj9_8 

Tried to do the same as shown on the video on ovirt 4.4.4, but no 
kubevirt provider is available. Is it an option when installing or an 
upcoming feature?


it is there, but only enabled by default in 4.4.5
there’s KubevirtProviderSupportEnabled vdc_option for that in older 
versions


Yes that's it, for those who want to quickly enable it in prior ovirt 
versions:


engine-config -s KubevirtProviderSupportEnabled=true




There is no plan to get oVirt merged into OKD.


Its not that easy since OKD designed primarily for
Kubernetes/Docker containers.

Or oVirt may be considered just another abandonware within 2+ years?


oVirt is not going to be abandonware as long as the community will

You don't need to use discard mount option. fstrim works without it.

Discarding data mark the areas in the qcow2 image as zero, but it does not move
actual data around (which is very slow). So if the clusters were at
the end of the
image they remain there, and the actual file size is the same.

The only way to reclaim the space is:
1. sparsify disk - must be done *before* copying the disk.
2. move this to another storage domain
3. move disk back to the original storage domain

We may have an easier and more efficient way in the future that
works with single storage domain, but it will have to copy the
entire disk. If the disk is really mostly empty it should be fast.

[ovirt-users] Re: How to restore Storage Domain from disaster recovery

[Miguel Garcia]

I solve the problem by login to host and run command 
ovirt-hosted-engine-cleanup as super user and respond yes to any question. 
Go to Storage -> Storage Domain on the ovirt portal and click Import Storage. 
Type the information of storage and selected cluster (none).
Open imported storage domain -> tab Data Center click Attach and select the 
desired Data Center. BTW the datacenter must support the Storage Domain Version.

Then proceed to import vms, disks, templates.

Hope you don't need this procedure.

We’ve seen people with 70+ machines being managed by shell scripts and libvirt, 
and also oVirt users with just a single host. Those would be extremes. I would 
personally start using oVirt once I have more than 4-5 hosts or so, and/or more 
than 20 VMs.

yeah, in a stretched cluster setup it would work, but the expectations are that 
the link is almost as local. It does work ok with several hundred ms latency. 
but it needs to be reliable.

I think none of the vendors are ready with their products to use incremental 
backup just yet. it’s close though.
you can also just adapt and use examples[1] of the incremental backup 
feature[2]. if you’d want to just hack up some DIY backup solution.
incremental backup us a fairly recent addition to oVirt (and to qemu/libvirt in 
general)

Its not that easy since OKD designed primarily for
Kubernetes/Docker containers.

Or oVirt may be considered just another abandonware within 2+ years?


oVirt is not going to be abandonware as long as the community will not 
abandon it.

[ovirt-users] Q: Sparsify/fstrim don't reduce actual disk image size

[Andrei Verovski]

Hi !

I have VM (under oVirt) with single disk thin provision (~600 GB) running 
NextCloud on Debian 9.
Right now VM HD is almost empty. Unfortunately, it occupies 584 GB (virtual 
size = 600 GB)
All partition (except swap and boot) are EXT4 with discard option. in oVirt 
“enable discard = on”.

# fstrim -av runs successfully:
/var: 477.6 GiB (512851144704 bytes) trimmed on /dev/mapper/vg--system-lv4--data
/boot: 853.8 MiB (895229952 bytes) trimmed on /dev/mapper/vg--system-lv2--boot
/: 88.4 GiB (94888611840 bytes) trimmed on /dev/mapper/vg--system-lv3—sys

When fstrim runs again, it trims zero. I even run “Sparsify” in oVirt. 
Unfortunately, actual size is still 584 GB.

Here is /etc/fstab
/dev/mapper/vg--system-lv3--sys /   ext4
discard,noatime,nodiratime,errors=remount-ro 0   1
/dev/mapper/vg--system-lv2--boot /boot   ext2defaults0  
 2
/dev/mapper/vg--system-lv4--data /varext4
discard,noatime,nodiratime 0   2
/dev/mapper/vg--system-lv1--swap noneswapsw  0  
 0

When disk was partitioned/formatted, swap and boot were created first and 
positioned at the beginning.

What is wrong here? Is it possible to fix all this ?

Thanks in advance.
Andrei

Perhaps using google drive? Perhaps split the file (if nothing else,

Some of them might be around your storage solution, but some do look
oVirt-specific.

[ovirt-users] Re: Destroyed VM blocking hosts/filling logs

[David Kerry]

Hello,

This seems to be what the engine is trying to do, and failing at for some 
reason.

eg:

[root@ovirt-node217 ~]# vdsm-client Host getVMList fullStatus=True
[
    "8b3964bc-cd3f-4f13-84c6-1811193c93eb",
    "132668b6-9992-451f-95ac-dbcbeb03f5f1"
]

For reference:

[root@ovirt-node217 ~]# virsh -r list --all
 Id    Name   State

 - vm-s2                      shut off
 - vm-s1                      shut off

And in the console, it shows a count of "2" beside this host, but on the host 
detail
page, under the virtual-machine tab, the list is empty (these VMs are actually
running on a different host).

[root@ovirt-node217 ~]# vdsm-client VM destroy 
vmID="8b3964bc-cd3f-4f13-84c6-1811193c93eb"
vdsm-client: Command VM.destroy with args {'vmID': 
'8b3964bc-cd3f-4f13-84c6-1811193c93eb'} failed:
(code=100, message=General Exception: ("'1048576'",))

I guess what I need is a way to remove/clean-up these VMs manually since ovirt
does not seem to be able to do it by itself.

This condition also blocks the host from being put into maintenance mode.

When I reboot the host manually and "confirm host was rebooted", the VMs
are still there and still stuck.

Sincerely,

David

Hello,

I've somehow gotten one of my VMs stuck in a state that ovirt seems to be 
rather confused about its
existence of now.  I'm running oVirt 4.3.10 and using oVirt Node on all the 
hosts.

My engine and host event logs are now filling up very rapidly with this 
error:

VDSM node217 command DestroyVDS failed: General Exception: ("'1048576'",)

I was playing with hugetable support, and that error number or string looks 
suspiciously
like the "hugetable size" custom property I set on the VM.

This VM was migrated to another host at one point as well, and now that 
host is also
generating the same error as well.

When I try to move these hosts to maintenance mode, they get stuck in 
"Preparing for
Maintenance" while it tries to migrate/deal with the VM that's not there 
any more.

Forcibly rebooting the hosts does not change anything.  The VM state/host 
seems to be
captured somewhere persistent in this case.

The VM in question is not running, and I can start it up on another host 
successfully,
but ovirt still thinks it exists on the other 2 hosts no matter what I do.

Is there perhaps some way to delete it from the engine database directly to 
straighten
things out?

Here's a dump of the vdsm log on one of the hosts.  I haven't been able to 
pinpoint what
the exact issue is or how to fix it, but hopefully someone here will have 
seen this before?

[ovirt-users] Re: Destroyed VM blocking hosts/filling logs

[Shani Leviim]

Hi,
You can try with the vdsm-client tool:
https://www.ovirt.org/develop/developer-guide/vdsm/vdsm-client.html

Stopping a VM:
1) Get the vmId:
# vdsm-client Host getVMList fullStatus=True

2) Destroy the VM
# vdsm-client VM destroy vmID=


*Regards,*

Hi,
You can use this one for adding a VM nic:

Can you please check also this thread:

https://lists.ovirt.org/archives/list/users@ovirt.org/thread/YH4J7GG7WLOLUFIADZPL6JOPDETJ23CZ/

What version was used for backup, and what version for restore?

Did you have a 3rd-party CA cert installed?

Please verify that it was backed up and restored correctly, or manually
reinstalled after restore.

Good luck and best regards,

Hi,
Did you try to refresh the page and try again?


Yes, several times. Also different browsers with no difference.


Can you share a screenshot?


Sure. Adding the screenshot in this e-mail. This happens after 
authenticating like admin (internal) on either the administration panel 
or the VM portal.


Thanks.
