I've having to rebuild an environment that started back in the early 3.x days. A lot has changed and I'm attempting to use the Ovirt Node based setup to build a new environment, but I can't get through the hosted engine deployment process via the cockpit (I've done command line as well). I've tried static DHCP address and static IPs as well as confirmed I have resolvable host-names. This is a test environment so I can work through any issues in deployment. When the cockpit is displaying the waiting for host to come up task, the cockpit gets disconnected. It appears to a happen when the bridge network is setup. At that point, the deployment is messed up and I can't return to the cockpit. I've tried this with one or two nic/interfaces and tried every permutation of static and dynamic ip addresses. I've spent a week trying different setups and I've got to be doing something stupid. Attached is a screen capture of the resulting IP info after my latest try failing. I used two nics, one for the gluster and bridge network and the other for the ovirt cockpit access. I can't access cockpit on either ip address after the failure. I've attempted this setup as both a single host hyper-converged setup and a three host hyper-converged environment...same issue in both. Can someone please help me or give me some thoughts on what is wrong?

Thanks a bunch for the reply Didi and Simone. I will admit this last setup was a bit of wild attempt to see if i could get it working somehow so maybe it wasn't the best example to submit...and yeah, should have been /24 subnets. Initially I tried the single nic setup, but the outcome seemed to be the same scenario.

Honestly I've run through this setup so many times in the last week its all a blur. I started messing multiple nics in latest attempts to see if this was something specific I should do in a cockpit setup as one of the articles I read suggested multiple interfaces to separate traffic.

My "production" 4.0 environment (currently a failed upgrade with a down host that I can't seem to get back online) is 3 host gluster on 4 bonded 1Gbps links. With the exception of the upgrade issue/failure, it has been rock-solid with good performance and I've only restarted hosts on upgrades in 4+ years. There are a few networking changes i would like to make in a rebuild, but I wanted to test various options before implementing. Getting a single nic environment was the initial goal to get started.

I'm doing this testing in a virtualized setup with pfsense as the firewall/router and I can setup hosts/nics however I want. I will start over again with more straightforward setup and get more data on failure. Considering I can setup the environment how i want, what would be your recommended config for a single nic(or single bond) setup using cockpit? Static IPs with host file resolution, DHCP with mac specific IPs, etc.

Thank you,

Todd Barton

There are two parts here: 1. Fix it so that you can continue (and so

that if it happens to you on production, you know what to do) 2. Fix

the code so that it does not happen again. They are not necessarily

identical (or even very similar).

At the point in time of taking the screen capture:

1. Did the ovirtmgmt bridge get the IP address of the intended nic? Which one?

2. Did you check routing? Default gateway, or perhaps you had/have

specific other routes?

3. What nics are in the bridge? Can you check/share output of 'brctl show'?

4. Probably not related, just noting: You have there (currently on

eth0 and on ovirtmgmt, perhaps you tried other combinations):

10.1.2.61/16 and 10.1.1.61/16 . It seems like you wanted two different

subnets, but are actually using a single one. Perhaps you intended to

use 10.1.2.61/24 and 10.1.1.61/24.

Good catch: the issue comes exactly form here!

Please see:

https://bugzilla.redhat.com/1694626

The issue happens when the user has two interfaces configured on the same IP subnet, the default gateway is configured to be reached from one of the two interfaces and the user chooses to create the management bridge on the other one.

When the engine, adding the host, creates the management bridge it also tries to configure the default gateway on the bridge and for some reason this disrupt the external connectivity on the host and the the user is going to loose it.

If you intend to use one interface for gluster and the other for the management network I'd strongly suggest to use two distinct subnets having the default gateway on the subnet you are going to use for the management network.

If you want to use two interfaces for reliability reasons I'd strongly suggest to create a bond of the two instead.

Please also notice that deploying a three host hyper-converged environment over a single 1 gbps interface will be really penalizing in terms of storage performances.

Each data has to be written on the host itself and on the two remote ones so you are going to have 1000 mbps / 2 (external replicas ) / 8 (bit/bytes) = a max of 62.5 MB/s sustained throughput shared between all the VMs and this ignoring all the overheads.

In practice it will be much less ending in a barely usable environment.

I'd strongly suggest to move to a 10 gbps environment if possible, or to bond a few 1 gbps nics for gluster.

5. Can you ping from/to these two addresses from/to some other machine

on the network? Your laptop? The storage?

6. If possible, please check/share relevant logs, including (from the

host) /var/log/vdsm/* and /var/log/ovirt-hosted-engine-setup/*.

Thanks and best regards,

Didi, I was able to carve out some time to attempt the original basic setup again this evening. The result was similar to my original post. During HE deployment, in the process of waiting for the host to come up (cockpit message), the networking is disrupted while building the bridged network and the host becomes unreachable. In this state, I can't ping the host from external machine and the ping/nslookup is non-functional from within the host. Nslookup returns "connection time out; no servers could be reached". The networking appears to be completely down although various command make it appear operational. Upon rebooting the Host (the host locked up on reboot attempt and needed to be reset), the message appears "libvirt-guests is configured not to start any guests on boot". After the reboot, the cockpit becomes responsive again and loging-in displays the "This system is already registered ovirt-dr-he-standalone.ipvoicedatasystems.lan!" with a "Redeploy" button. Looking at the networking setup in cockpit, it appears the "ovritmgmt" network is setup, but the hosted engine did not complete deployment and startup. The /etc/host file still contains the temporary IP address used in deployment and a HostedEngineLocal is listed under virtual machines, but it is not running. Please advise with any help/input on why this is happening. *Your help is much appreciated.* Here are the settings and diagnostic info/logs. This is a single-host hyper-converged setup for lab testing. - Host behind pfsense firewall with gateway IP address 10.1.1.1/24. The Host machine and the machine accessing the cockpit from IP address 10.1.1.101 are the only devices on the subnet (other than the router). It really can't get any simpler. - Host setup with single nic eth0 - Hostname is setup as fully FQDN on Host - Static IP setup on Host with gateway and DNS server set to 10.1.1.1 - FQDNs confirmed resolvable on subnet via dns server at 10.1.1.1 in pfsense Host = ovirt-dr-standalone.ipvoicedatasystems.lan , IP = 10.1.1.61 Hosted Engine VM = ovirt-dr-he-standalone.ipvoicedatasystems.lan , IP = 10.1.1.60 - Gluster portion of cockpit setup installed as expected without problems

- Hosted-Engine cockpit deployment executed with settings in attached screen shots. - Hosted engine setup and vdsm logs are attached in zip before the reboot. - Other network info captured in text files included in zip. - Screen shot of post reboot network setup in cockpit.

I've followed best practices/recommendations, but realize there are not absolute specifics in these recommendations...there are a lot of either/or statements...which is why I was asking for recommendations. I've reviewed many articles including the "up and running" one like https://ovirt.org/blog/2018/02/up-and-running-with-ovirt-4-2-and-gluster-..., In everything I've looked at there isn't anything new or different vs what I've already done or attempted. I was very methodical in my initial attempts as I did in my initial install of v3.3 years ago which took many attempts and methodical configuration to get it up and setup the way I wanted. What I'm trying to understand is why its not coming up in a lab setting with what I would consider to be a pretty remedial setup. I'll get back to a basic setup and run through the process again today or tomorrow and post logs of the failure.

Considering I can setup the environment how i want, what would be your recommended config for a single nic(or single bond) setup using cockpit? Static IPs with host file resolution, DHCP with mac specific IPs, etc. Much of such decisions is a matter of personal preferences, acquaintance with the relevant technologies and tooling you have around them, local needs/policies/mandates, existing infrastructure, etc. If you search the net, e.g. for "ovirt best practices" or "RHV best practices", you can find various articles etc. that can provide some good guidelines/ideas. I suggest to read around a bit, then spend some good time on planning, then carefully and systematically implement your design, verifying each step right after doing it. When you run into problems, tell us :-). Ideally, IMO, you should not give up on your design due to such problems and try workarounds, inferior (in your eyes) solutions, etc., unless you manage to find existing open bugs that describe your problem and you decide you can't want until they are solved. Instead, try to fix problems, perhaps with the list members' help. I realize spending a week on what is in your perception a simple, straightforward task, does not leave you in the best mood for such a methodical next attempt. Perhaps first take a break and do something else :-), then start from a clean and fresh hardware/software environment and mind.

(jsonrpc/5) [jsonrpc.JsonRpcServer] RPC call Host.setSafeNetworkConfig succeeded in 0.02 seconds (__init__:312) where Host.setSafeNetworkConfig means that the engine committed the new network configuration since everything was fine from its point of view. And after that we also have: 2019-05-01 20:22:29,748-0400 INFO (jsonrpc/7) [api.host] START getHardwareInfo() from=::ffff:192.168.122.13,47544 (api:48) 2019-05-01 20:22:29,805-0400 INFO (jsonrpc/7) [api.host] FINISH getHardwareInfo return={'status': {'message': 'Done', 'code': 0}, 'info': {'systemProductName': 'Virtual Machine', 'systemUUID': 'cb4aee34-27aa-064d-aaf1-2c27871125bc', 'systemSerialNumber': '9448-7597-9700-7577-0920-4186-69', 'systemVersion': '7.0', 'systemManufacturer': 'Microsoft Corporation'}} from=::ffff:192.168.122.13,47544 (api:54) So I'm pretty sure that the engine VM was correctly able to talk with the host after the network configuration change so, on my opinion, we should focus somewhere else. If I correctly understood you environment you have: - A pfsense software firewall/router on 10.1.1.1 - Your host on 10.1.1.61 - You are accessing cockpit from a browser running on a machine on 10.1.1.101 on the same subnet And the issue is that once the engine created the management bridge, your client machine on 10.1.1.101 wasn't able anymore to reach your host on 10.1.1.61. Am I right? In this case the default gateway or other routes should't be an issue since your client is inside the same subnet. Do you think we are loosing some piece of your network configuration creating the management bridge such as a custom MTU or a VLAN id or something like that? Do you think pfsense can start blocking/dropping the traffic for any reason? Dominik, any hint from you?

Simone/Dominik, Double reply below and more info with latest attempt. --------------- Simone...answers to your questions, using CAPS to make my responses easier to see/read. "If I correctly understood you environment you have: - A pfsense software firewall/router on 10.1.1.1 - Your host on 10.1.1.61 - You are accessing cockpit from a browser running on a machine on 10.1.1.101 on the same subnet" YES "And the issue is that once the engine created the management bridge, your client machine on 10.1.1.101 wasn't able anymore to reach your host on 10.1.1.61. Am I right?" YES "In this case the default gateway or other routes should't be an issue since your client is inside the same subnet." CORRECT, IMO "Do you think we are loosing some piece of your network configuration creating the management bridge such as a custom MTU or a VLAN id or something like that?" NO CUSTOM SETUP HERE...RUNNING A PLAIN/BASIC NETWORK "Do you think pfsense can start blocking/dropping the traffic for any reason?" NO, ONLY USING PFSENSE TO PROVIDE DHCP AND DNS IN TEST/LAB ENVIRONMENT. "Todd, another hint: how did you exposed cockpit over firewalld? Maybe something in firewalld zone configuration?" I'M USING THE OVIRT NODE MINIMAL/UTILITY INSTALL AND I DIDN'T DO ANY CUSTOMIZATION OUTSIDE OF THE INSTALL/SETUP. IF ITS FIREWALLD, THEN ITS NOT SOMETHING THE NODE SETUP DID PROPERLY. I CAN SEND CONFIG INFO IF YOU WOULD LIKE SEE IT, BUT THERE ARE MORE DEVELOPMENTS/INFO FURTHER DOWN IN THE EMAIL FROM ADDITIONAL EFFORTS. --------------- Dominik, It is in a virtualized setup as I'm testing install/setup of this version of ovirt/node mainly as a lab/testing setup, but I was hoping to use this environment as a temporary data center to keep critical VMs running if necessary while performing the reinstall/rebuild of my physical system. I'm running this in hyper-v with the virtual switch/network setup as a private network with no restrictions from what I can see. The VMs are setup to allow mac spoofing and the mac addresses are all unique. The virtualization could the be the culprit, but I have no idea how/why it would be causing a problem during this specific point of the install. See new info below and I'm curious about your thoughts on this issue. --------------- **** Additional info from "Redeploy" option **** To see what would happen, I attempted the "Redeploy" option in the cockpit after the reboot described in previous email. Upon Redeploy using the same settings, it made it through the "Prepare VM" stage. I didn't manually perform a hosted-engine cleanup command, but it looked like deploy script cleaned up everything before attempting the redeployment. I've repeated this behavior twice, so for some reason the redeployment works after the 1st failure. Continuing on to specify the "storage" settings to finalize deployment, it failed at "Obtain SSO token using username/password credentials" because it couldn't connect to the engine. The HostedEngineLocal is running on the Host with 192.168.122.13 as the IP (the temp IP). Trying to ping that address from the Host gets a "Destination Host Unreachable" from 192.168.122.1. Logging into the HostedEngineLocal console from the cockpit, I can't ping 192.168.122.13 getting the same unreachable message from within the hosted-engine,

but I can ping the Host address 10.1.1.61 from within the hosted-engine. I'm assuming the hosted-engine should still be on this temp/private IP until after completion of the HE deployment.

It seems like if I could make 192.168.122.13 routable from the Host, I could get this to work. Any advice on how to fix this?...I don't understand why I can't ping 192.168.122.13 from anywhere.

I've attached logs and ip info commands from Host as well as screen shots from cockpit including storage/final deployment error and hosted-engine basic networking info.

Simone, It appears 192.168.122.13 stops routing correctly during the final stage of deployment. After a failure of final stage, I can restart the hosted-engine VM from the cockpit and I can ping 192.168.122.13 from the Host again. If I retry the final stage of deployment again, 192.168.122.13 stop routing correctly from Host during that process. Below are two ping commands...the 1st one is after deploy failure (screen shot previous email) and the second one is after force-restarting the hosted-engine VM.

Maybe this is something caused by the virtualization setup, but I've read about others doing ovirt hosts in VMs (like https://www.ovirt.org/blog/2018/02/up-and-running-with-ovirt-4-2-and-glus... ).

Any suggestions? I'm getting to the point where I may need to throw in the towel on this setup, but it would be greatly advantageous to have a VM lab so I can test changes/upgrades. I would love to find a way to make this work. *Todd Barton* ---- On Fri, 03 May 2019 12:04:47 -0400 *Simone Tiraboschi <stirabos(a)redhat.com <stirabos(a)redhat.com&gt;&gt;* wrote ---- On Fri, May 3, 2019 at 5:27 PM Todd Barton < tcbarton(a)ipvoicedatasystems.com&gt; wrote: Simone/Dominik, Double reply below and more info with latest attempt. --------------- Simone...answers to your questions, using CAPS to make my responses easier to see/read. "If I correctly understood you environment you have: - A pfsense software firewall/router on 10.1.1.1 - Your host on 10.1.1.61 - You are accessing cockpit from a browser running on a machine on 10.1.1.101 on the same subnet" YES "And the issue is that once the engine created the management bridge, your client machine on 10.1.1.101 wasn't able anymore to reach your host on 10.1.1.61.

CORRECT, IMO "Do you think we are loosing some piece of your network configuration creating the management bridge such as a custom MTU or a VLAN id or something like that?" NO CUSTOM SETUP HERE...RUNNING A PLAIN/BASIC NETWORK "Do you think pfsense can start blocking/dropping the traffic for any reason?" NO, ONLY USING PFSENSE TO PROVIDE DHCP AND DNS IN TEST/LAB ENVIRONMENT. "Todd, another hint: how did you exposed cockpit over firewalld? Maybe something in firewalld zone configuration?" I'M USING THE OVIRT NODE MINIMAL/UTILITY INSTALL AND I DIDN'T DO ANY CUSTOMIZATION OUTSIDE OF THE INSTALL/SETUP. IF ITS FIREWALLD, THEN ITS NOT SOMETHING THE NODE SETUP DID PROPERLY. I CAN SEND CONFIG INFO IF YOU WOULD LIKE SEE IT, BUT THERE ARE MORE DEVELOPMENTS/INFO FURTHER DOWN IN THE EMAIL FROM ADDITIONAL EFFORTS. --------------- Dominik, It is in a virtualized setup as I'm testing install/setup of this version of ovirt/node mainly as a lab/testing setup, but I was hoping to use this environment as a temporary data center to keep critical VMs running if necessary while performing the reinstall/rebuild of my physical system. I'm running this in hyper-v with the virtual switch/network setup as a private network with no restrictions from what I can see. The VMs are setup to allow mac spoofing and the mac addresses are all unique. The virtualization could the be the culprit, but I have no idea how/why it would be causing a problem during this specific point of the install. See new info below and I'm curious about your thoughts on this issue. --------------- **** Additional info from "Redeploy" option **** To see what would happen, I attempted the "Redeploy" option in the cockpit after the reboot described in previous email. Upon Redeploy using the same settings, it made it through the "Prepare VM" stage. I didn't manually perform a hosted-engine cleanup command, but it looked like deploy script cleaned up everything before attempting the redeployment. I've repeated this behavior twice, so for some reason the redeployment works after the 1st failure. Continuing on to specify the "storage" settings to finalize deployment, it failed at "Obtain SSO token using username/password credentials" because it couldn't connect to the engine. The HostedEngineLocal is running on the Host with 192.168.122.13 as the IP (the temp IP). Trying to ping that address from the Host gets a "Destination Host Unreachable" from 192.168.122.1. Logging into the HostedEngineLocal console from the cockpit, I can't ping 192.168.122.13 getting the same unreachable message from within the hosted-engine, This looks really strange to me. I'd suggest to focus on this. but I can ping the Host address 10.1.1.61 from within the hosted-engine. I'm assuming the hosted-engine should still be on this temp/private IP until after completion of the HE deployment. Until 85% of the process. Then it will shutdown the local bootstrap VM (running on default natted libvirt network) and it will transfer the content of it's disk over the disk created by the engine on the shared storage. Latest step is simply activating ovirt-ha-agent to let it start the engine VM from the shared storage as expected. The final engine VM will be attached to the management bridge created by the deployment process. It seems like if I could make 192.168.122.13 routable from the Host, I could get this to work. Any advice on how to fix this?...I don't understand why I can't ping 192.168.122.13 from anywhere. The default libvirt network has its specific bridge; the host has address 192.168.122.1 there and it will be able to communicate to the VM running on 192.168.122.13. Other machines are not required to communicate with the engine during the deployment so we are not routing 192.168.122.1/24 neither masquerading it for NAT traversal. I've attached logs and ip info commands from Host as well as screen shots from cockpit including storage/final deployment error and hosted-engine basic networking info.
