PostgreSQL password for ovirt 4.4.7
by louisb＠ameritech.net 22 Jul '21

22 Jul '21

I've finally installed successfully ovirt 4.4.7 using the default installation. I would like to change the passwords for the following userids: postgres, engine database and data warehouse database. Can someone provide me with information grading the files that contain the password to these items? I would also like to know the best way to change the passwords. Thanks

Cannot start hosted-engine
by Valerio Luccio 21 Jul '21

21 Jul '21

Hi list, I have a hosted engine running on a CentOS 8. The engine and all the VM's are stored on a 4-node gluster. I had some issues with the gluster and then the hosted-engine stopped working (even though the virtualization dashboard showed 4 virtual machines running). I tried to "systemctl restart" the hosted-engine, but it failed. I try to reboot the server and the hosted-engine still will not come up. Note that the server has no issue mounting the gluster: $ df hydra1:/MRIData 390664407040 20530130012 370134277028 6% /rhev/data-center/mnt/glusterSD/hydra1:_MRIData $ ls -l /rhev/data-center/mnt/glusterSD/hydra1\:_MRIData/6547dc22-b89e-4f14-8958-c9e8d27b29a4/ drwxr-xr-x. 2 vdsm kvm 4.0K Mar 29 12:24 dom_md drwxr-xr-x. 2 vdsm kvm 4.0K Jul 20 17:47 ha_agent drwxr-xr-x. 12 vdsm kvm 4.0K Apr 1 16:32 images drwxr-xr-x. 4 vdsm kvm 4.0K Mar 29 12:24 master Where "hydra1" is one of my gluster nodes and MRIData is the volume name.

The fqdn of the hosted engine resolves fine on the server, so does the fqdn of the server itself. The ip address it seems to try to use for the network is that of one of the university's gateways. Any ideas ? Any way to debug this further ?

Reconfigure Gluster from Replica 3 to Arbiter 1/Replica 2
by David White 21 Jul '21

21 Jul '21

My current hyperconverged environment is replicating data across all 3 servers. I'm running critically low on disk space, and need to add space. To that end, I've ordered 8x 800GB ssd drives, and plan to put 4 drives in 1 server, and 4 drives in the other. What's my best option for reconfiguring the hyperconverged cluster, to change gluster storage away from Replica 3 to a Replica 2 / Arbiter model? I'd really prefer not to have to reinstall things from scratch, but I'll do that if I have to. My most important requirement is that I cannot have any downtime for my VMs (so I can only reconfigure 1 host at a time). Sent with ProtonMail Secure Email.

Automatic Shutdown / Startup for Hosted-Engine
by Eugène Ngontang 18 Jul '21

18 Jul '21

Hi, I understood we have to put hosted-engine into maintenance mode and shutdown the VMs if we want to power off the host (otherwise it will reboot). I'm setting up a process to - put the HestedEngine in global maintenance mode (*hosted-engine --set-maintenance --mode=global*) - shutdown the HostedEngine (*hosted-engine --vm-shutdown*) - PowerOff the HostedEngine (*hosted-engine --vm-poweroff*) - Power off the server (*shutdown -P*) Everything works fine and I can start the server back up, remove the HostedEngine from maintenance mode, and it will start automatically running. The issue is when bringing up hosted-engine: all VMs come up but one (*BigIP*) and I am trying to see if there is way to bring it up without having to store the engine password (using the *ovirt_vm* API). At the moment, I am having to look for the BigIP VM and then use credentials to bring it up: it will not come up with 'hosted-engine --vm-start' Is there to make this specific VM start the same time as the others VM automatically when HostedEngine starts? Thanks for your help.

Removing Direct Mapped LUNs
by Ryan Chewning 16 Jul '21

16 Jul '21

Hi List, We need to add and remove directly mapped LUNs to multiple VMs in our Non-Production environment. The environment is backed by an iSCSI SAN. In testing when removing a directly mapped LUN it doesn't remove the underlying multipath and devices. Several questions. 1) Is this the expected behavior? 2) Are we supposed to go to each KVM host and manually remove the underlying multipath devices? 3) Is there a technical reason that oVirt doesn't do this as part of the steps to removing the storage? This is something that was handled by the manager in the previous virtualization that we used, Oracle's Xen based Oracle VM. Thanks! Ryan

ovirt (two nodes & iscsi san)
by edp＠maddalena.it 16 Jul '21

16 Jul '21

Hi. i am trying to set up an environment with two ovirt nodes connected to a san in iscsi. every node has a direct connection to the san (with a point-to-point connection). so every node talks with the san on a different iscsi channel with a different ip. in this case (i have just tried) when I shut down ovirt-node1 the ovirt-engine cannot restart automatically on ovirt-node2. maybe this because when I have configured hosted engine I have moved the engine storage to the iscsi lun that only the node1 can see (the ovirt-engine-setup asks for the iscsi ip address). In this case how can I resovle my problem? other than moving the ovirt-engine from one node to the other I have also to publish other luns to both ovirt nodes. but if every node talks only with one channel of the iscsi san I think that this won't working. If i put a 10 gb switch between ovirt-nodes and san channels can working? what I would like to do is connect the two ovirt nodes to the switch and also the two iscsi channels of the san to the switch. in this way each node should be able to talk to the san on both ip (iscsi channels) thank you
