[ovirt-users] Re: Multiple hosts stuck in Connecting state waiting for storage pool to go up.

[Murilo Morais]

Yesterday I went through the same situation after our router crashed and
bugged the connections with the Hosts.

The solution is quite simple and already documented by Red Hat. [1]

Just restarting the hosted-engine solves the problem.
`systemctl restart hosted-engine`

[ovirt-users] Error 500 when adding a new host

[Murilo Morais]

Good afternoon everybody.

I'm using oVirt 4.4.10 at the moment.

After activating Cinder, I believe that some packages were updated, which
is causing some problems, one of them is occurring when I try to add a
Host, then it shows a 500 error, the same is happening when editing a Host.

The following error is happening in the server.log:
2023-03-16 10:54:39,651-04 ERROR [io.undertow.servlet] (default task-133)

[ovirt-users] Re: RBD Mirror support

[Murilo Morais]

Of course OpenStack would be much better, unfortunately we need it in oVirt
while we don't implement OpenStack.

I am aware of the hack of the hack of another hack. We'll have to do that
while we don't implement another alternative to oVirt.

Konstantin, thank you so much for replying.

I'll see what I can do around here. Any news I update here on the list.

[ovirt-users] Re: RBD Mirror support

[Murilo Morais]

I understand. Is there no setting in Cinder to make this possible?

I'm thinking of writing a hook specifically for this, I don't see any other
alternative.

[ovirt-users] RBD Mirror support

[Murilo Morais]

Good evening everyone!

Guys, I managed to raise the RBD through Cinder without problem. Everything
works, including removing the Storage Domain (through postgres).

The initial objective was to go up with RBD Mirror but I'm not succeeding,
because Cinder is connecting the volume through KRBD, it doesn't support
Journaling which ends up breaking the Mirror...

Is there any way/configuration for Cinder to start the machine using librbd
instead of KRBD? Because in my scenario we have to use Mirror.

Thanks in advance.

[ovirt-users] Failed to remove MBS

[Murilo Morais]

Good afternoon everybody!

I have an MBD (Managed Block Storage) Storage Domain that we no longer use,
we want to remove it. We are using version 4.4.10.

When trying to put the Storage Domain in Maintenance, a message appears
saying that it was not possible to remove it and that there is a Task being
executed. I already looked for it but I didn't find it.

Therefore, I cannot put the Storage Domain in Maintenance in the
Datacenter, making it impossible to carry out the removal.

According to a Bug Report [1] the problem has been fixed in version 4.5.0,
the problem is that we cannot perform the update.

In the DB I found two references to this Storage Domain, one in the
`storage_domain_static` table and another in the `cinder_storage` table. Is
removing these two references enough to remove this Storage Domain?

Is there any other way to perform this process manually?

[ovirt-users] Move disk between POSIX FS and Managed Block Storage

Good morning everybody!

Guys, I managed to connect my oVirt cluster to the CEPH RBD, the VM disks
are stored in CephFS (POSIX FS). How can I move the disk from POSIX FS to
Managed Block Storage?

[ovirt-users] Re: Hosted Engine No Longer Has IP Address - Help!

[Murilo Morais]

If you want to access the Console you can use the following:
hosted-engine --console [1]

If it doesn't work (with me sometimes it doesn't work) you can access the
console via VNC:
hosted-engine --add-console-password --password= [2]

If you just want to restart the VM you can do the following:
hosted-engine --vm-shutdown
# Check with --vm-status until the VM dies
hosted-engine --vm-start


Perform these procedures in global maintenance mode.

[ovirt-users] VM stuck reading and writing to disk

[Murilo Morais]

Good morning people. I'm experiencing a weird problem.

I have a specific VM that the IO simply crashes.

This VM, during the backup period, executes mysqldump and tries to
compress, after a long period of compacting the JBD2 process appears using
100% of the CPU and also of WA (Wait in the TOP command). Numerous other
VMs perform the same process but only this one remains in this state. When
JBD2 appears, it is necessary to perform a forced reboot, because it stops
practically everything.

I'm using CephFS as Storage Backend. In the VM I can get rates of at least
600 Megs, I can generate gigs and more gigs of data without any problem.

The VMs are using Virtio instead of Virtio-blk.

Hosts are interconnected on 10G SFP+ interfaces, Storages on 40G interfaces.

I believe that the problem is not the Storage, as this behavior does not
exist in other VMs.

What I find strange is that JBD2 goes up and spikes at 100%.

What could be happening? Could it be something in the Guest itself?

[ovirt-users] RBD support

[Murilo Morais]

Good night people!

How is CEPH (RBD) supported through Cinderlib? How about latency? Is it
more performant to use CephFS or RBD through Cinderlib?

Thanks a lot in advance!

[ovirt-users] Re: Forced restart when losing communication with the Storages

[Murilo Morais]

Unfortunately, I haven't found anything like this.
At least this type of event didn't happen again, but I just can't find
anything in the logs that justifies these reboots, I've read everything
line by line, if anything was recorded there it passed my eyes.

[ovirt-users] Re: Forced restart when losing communication with the Storages

[Murilo Morais]

Konstantin, thank you very much for the explanation, it was very
enlightening.

I believe I left something open in the previous message.

I'm using Hosted Engine, all VMs have HA enabled and Power Management is
disabled on all hosts. No IPMI configured (at least I didn't configure
anything about iLO/IPMI in oVirt).

There was a loss of communication with the Storage for approximately 3
minutes and this caused all Hosts to reboot.

[ovirt-users] Forced restart when losing communication with the Storages

[Murilo Morais]

Good morning everyone!

Is there a way to disable the forced reboot of the machines? This morning
there was an event in our infrastructure where the hosts lost communication
with the Storage but this caused all the hosts to restart abruptly.

Would this be the correct behavior of oVirt? Is there any way to disable
this?

[ovirt-users] Re: oVirt/Ceph iSCSI Issues

[Murilo Morais]

Matthew, good morning.

Is iSCSI Target configured with ACL?
Do all Gateways have the same amount of active sessions? It could be that
some Gateway has crashed the sessions (specifically gateway 3).

If you are not actually using Storage Domain on iSCSI, I recommend the
following:
1- Logout through oVirt
2- Check if there is still an initiator in the multipath on each oVirt Host
3- Log out of all sessions and delete through iscsiadm on each oVirt Host
4- Check if there is still an active session in CEPH
5- Restart all Gateway Daemons in CEPH, it may take a while if there is a
stuck session
6- Try to perform Discovery again through oVirt

[ovirt-users] How are statistics collected for disk and network?

[Murilo Morais]

Good afternoon everyone.

Is there any way to collect disk and network statistics from VMs without
needing to install qemu-guest-agent? From what I noticed, this data only
appears in Grafana after installing this package on each VM, is that really
the case? Is there no way to collect this data without the need for the
package? At least for the network interface I can see the traffic of the VM
interface, but this data is not shown in Grafana.

Thanks in advance!

[ovirt-users]Re: Blog Post - Using Ceph Only Storage For oVirt Datacenter by Sandro Bonazzola – Wednesday 14 July 2021

[Murilo Morais]

Matthew, good morning!

If using iSCSI there is no need to copy /etc/ceph/.

Configure the credentials through the Dashboard, do not use the Mutual
User/Password, you can leave it blank, in the Target configuration, uncheck
the "ACL authentication" option.

[ovirt-users] Host restarting with error

[Murilo Morais]

Good morning gentlemen.

I have a weird problem with a setup I finished.

I'm using oVirt 4.4 Hosted Engine with NFS as Storage Domain, it happens
that, if the Storage disconnects, in a few minutes the machine restarts and
the red LED lights up as if there had been a crash.

I managed to capture a screenshot of this moment once, OOM-Killer killed
modprobe which doesn't make much sense as there is no VM other than the
Hosted Engine and there is 128G of RAM on the machine.

[ovirt-users] Local and remote storage

[Murilo Morais]

Good evening everyone.

Guys, I have two machines that use oVirt, I managed to put CephFS as a
storage domain and everything is working perfectly, but on these two
machines there are 4 NVMe on each, I would like to know if there is any
possibility or any way to use their local storage? I don't care if the host
dies and I don't get the VM up on the other, as it would be for very
specific cases, so there's no problem with that.
