Host is not added in known_hosts
by admin＠foundryserver.com
ok I am setting up the gluster file system.
I have the following completed
- able to ssh into all three hosts from host1 without password prompting.
- on each host I have host file entries for host{x}.private.net
- on public dns, I have host{x}1.fg.net
- each host has a public nic and private nic.
- I have all three hosts added in the dashboard
- I am able to ping all three on private and public nic from host1
When I go to add the hosts in the setup, it looks like 2 and 3 are fine with no errors, but host1 entry gives me "Host is not added in known_hosts" error. I am doing this setup from host1. It feels like there is a link to being on host1 and host1 having the error. I am still google fooing as we speak to try and find an error. The only thing I have not done, is setup host 2 and 3 to be able to ssh into all the other boxes.
Any thoughts would be greatly appreciated. Happy to share screen shots if it would help.

Hi Team

Engine backup / restore
by duparchy＠esrf.fr
Hi,
I'm testing Backup / Restore of the engine.
Once the engine is restored ; how to resync the engine database with the "reality" of the Storage Domains ? (I'm talking about anything that could have been done after the engine backup : Deleted / Created VMs ; Snapshots taken since the backup, etc..
I'm on 4.3, Oracle LVM context.
My Tests :
- Create a snapshot of some random VM. Say VM-1
- Enable that VM preview and start it on a host.
- Stop OLVM engine server.
- Start a full backup copy of that OLVM engine (That backup being a snapshot taken, say, yesterday. Our test OLVM engine being a VM running in another separate virltualization infrastucture.)
The restored OLVM does not show the existence of the VM-1 snapshot. It only shows the VM running on the active instance. No snapshot.
I tried Storage Domain / Scan disks. No refresh to be seen.

I'll let the storage team to reply to this, but it seems stable enough for

prod network glitch after reboot lab server
by Dominique D
Hi,
I have two ovirt environments on the same network.
2 switches (10G switch for storage and 1G switch for data / management)
1) Prod environment:
3 oVirt 4.4.6 nodes (1 port 10G per node for storage gluster and 1 port 1G for data / management)
2) Lab environment
2 oVirt nodes 4.4.6 (1 Port 10G per node for storage gluster and 1 port 1G for data / management)
The storage is on the same vlan and subnet for both environments.
When I restart one of my lab servers, I have communication cuts/glitch on my production ovirt clusters. I even had server reboots.
Do you know why ?
Here somes log :
VDSM ovnode1.telecom.lan command SpmStatusVDS failed: Connection timeout for host 'ovnode1.telecom.lan', last response arrived 42479 ms ago.
Host ovnode1.telecom.lan is not responding. It will stay in Connecting state for a grace period of 88 seconds and after that an attempt to fence the host will be issued.
Invalid status on Data Center Default. Setting Data Center status to Non Responsive (On host ovnode1.telecom.lan, Error: Network error during communication with the Host.).
Host ovnode1.telecom.lan cannot access the Storage Domain(s) datassd attached to the Data Center Default. Setting Host state to Non-Operational.

Ovirt VM started with the most recent snapshot with the current disk missing
by Xiaoyu Hu
Dear Ovirt folks,
I am faced with a very strange situation with Ovirt 4.3. A virtual machine has two snapshots and a working disk, with the former two snapshots being read only and the working one read-write. After an unplanned power outage, a virtual machine can only be started with the recent snapshot, and the actual working disk is missing in the Ovirt UI. I can see the disk still exists in the backend storage, but it seems not Ovirt does not know it. Thus the VM lose the recent data on the missing disk.
Does any one know whether this is a known bug in Ovirt 4.3, or is there a method to resotre the missing working disk back to the virtuanl machine? Otherwise i am faced with a terrible data loss issue on Ovirt
best regards,
Samuel

GPG key <infra@ovirt.org> expired since April ?

Hi,
According to output pasted below it seems that the GPG key used to sign installation media has expired 2021-04-03. Why is new installation ISO signed 7 days ago with a key that has been expired for almost 6 months? Is this correct?
My main question though is if this iso is authentic?
