Hi
This is a far as I could get today. frustrating! I can't connect to
ovirt-gluster.whichelo.com after install. I can ping the ip no successfully,
everything is correct in DNS

Hi Sorry about the delay! Here is what I did - which for some reason got further than before, but still failed at the last hurdle! Maybe just doing this exercise of commenting my workflow helped me to fix errors I'd not seen before - I don't know! Have any packages been updated I don't know about? https://docs.google.com/document/d/1SslZJYokA-Ho8SN8Vr5IzTnItuIDA6ACjilvLgCLcQ0/edit?usp=sharing Here are the logs from the failed gluster deploy, before I commented out the filter in lvm.conf https://docs.google.com/document/d/1uvICx4NBMjC68hhPN98f-LAykyHUPvX5ipr-dUKk32s/edit?usp=sharing I will update this thread as may be of use to some. Is there anywhere I should post it that other might find easier? Any advice on this final hurdle would be very gratefully received! I have to go do some family stuff, but will update later if I find a solution! ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/T5PG64I23UALXBCE2HAW7OKO4TWYTFH5/

Many thanks Didi I will do this later - I think it may be of benefit to others. I'll start a fresh install on my server and detailed (I'm basically following the Ovirt flow) flow. I'll try get the logs into my gdrive so as not to leave messy posts. I've got my desktop plugged into the same switch as the server. The switch is running DNSMasq and runs the DNS on 192.168.0.2. Network gateway and DHCP server is 192.168.0.1, which is where my internet comes in. DHCP runs from 192.168.0.3 - 30. I assign static IPs for the server services from 192.168.0.40 onwards. I have 2 x 2 port 1Gb nics (4 ports total) on the server. 2 are connected to the router. I'll post everything else later today.

[ovirt-users] Single Node Hyperconverged - Failing Engine Deployment - Network setup?
Ovirt newbie here - installing v 4.4.4 (well, trying to!) Following my post about failing Gluster setup, I can't get the self hosted engine to deploy. I'm installing on my HP DL380p G6. I have 2 disk 170GB Raid 0 for OS and 6 x 330GB disk Raid 5 for Gluster. DNS all set up, but Im realizing I'm missing something here. I have a feeling my problems with Gluster/Engine were caused by incorrect network setup. Seems I'm not the 1st to fall at this hurdle - some people in the community are saying RH have made it's deliberately difficult to get these 'free' set-ups working. It does feel a little like that! Most instructions just say that a 'self hosted, hyperconverged, single node setup requires 2 nics' - and that's about it! That is the 'Networking Pre-requisites'! I've had some help on here and Reddit which eventually made me find a solution some had had to use - editing lvm.conf to make sure my drive (sdb) was being blacklisted correctly. So, with that, Gluster installs, with following DNS settings: The kvm host (ovirt-kvm.whichelo.com) is fixed ip 192.168.0.40 on my 1st nic (Enp0s7) ovirt-engine.whichelo.com - 192.168.0.50 and ovirt-gluster.whichelo.com on 192.168.0.60 - I created I VLAN linked to the nic i want to use for gluster (Enp0s8) and gluster install worked. So now hosted engine won't install,, and pretty sure it's because I don't know how to set the network up properly. I'm seeing virbr0 coming up with different ip's - sometimes 192.168.1.1, sometimes 192.168.222.1. From what I've read, this is something to do with the Engine's network, but I really don't know! Am I still missing something? I can't find any decent instructions on how to do this - how (exactly) to configure the 2 'minimum required' nics? I came to Ovirt after realizing Oracle were dumping their own Virtualization platform in favour of KVM. Couldn't set it up from Oracle so moved to Red Hat - that was a no, and I was at the point where it made most sense to just run an Ovirt node for my KVM. I've got much further with Ovirt, but instructions do not work as easily as they looked! (example 'just click on single node hyperconverged' which didn't work straight off the bat until removing that LVM filter, which took days to find out! The single node HC server is a great match for a home lab/server like mine. I don't want another server, let alone another 2! I'm doing this partly as hobby, but also to update my skills during lockdown. Surely if we can get people using things like this at home, they're more likely to end up using it for work one day? Any help, or just pointing in the right direction, gratefully received! Hopefully I'm a biit clearer here.

[ovirt-users] Re: Single Node Hyperconverged - Failing Gluster Setup
Hi I've learned a lot today reading, but still not smooth sailing at all! I'm just doing a fresh install as I did find one way out of my above problem - to comment out the filters in /etc/lvm/lvm.conf - but I couldn't see why this worked!? I'm going to clean sdb once install finishes then look at the lsblk output to check all is well. I had found that sdb was being tagged as type mpath, which I managed to fix with wipefs. So hopefully that will be ok this time round. What I have found is that I'm still having problems working ou t the logic of the network The kvm host (ovirt-kvm.whichelo.com) is fixed ip 192.168.0.40 on my 1st nic Also in my DNS are ovirt-engine.whichelo.com - 192.168.0.50 and ovirt-gluster.whichelo.com on 192.168.0.60 I discovered that adding gluster's ip to that adapter allowed me to move on with provisioning, but if I add the engine's (.50) I get the he_FQDN resolves to this host message. I'm just working out how to use the nic's (machine has 4), bonds and vlans. Installation always stalls at "waiting for host to be up" - I'm guessing my dodgy networking is causing problems. Any help for a newbie would be very welcome! Is there any way to post screenshots? Thank you so much for trying to help me out! I've found people in the ovirt community very helpful. ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/TUCMED2CEZBLATO7JZIBG6TWUBSBCLZ5/
[ovirt-users] Single Node Hyperconverged - Failing Gluster Setup
Ovirt newbie here - using v 4.4.4
Have been trying for days to get this installed on my HP DL380p G6. I have 2
disk 170GB Raid 0 for OS and 6 x 330GB disk Raid 5 for Gluster. DNS all set up
(that took some working out), but I just can't fathom out whats (not) happening
here. Block size is returned as 512.
I've had some help on Reddit where I've been told that Ovirt is seeing my
single local disk ass an multipath device, which it is not/??! I think I
removed the flag, but it still fails here.
So, Gluster install fails quite early through, though it carries on creating
all the volumes (with default settings) but then gives me the 'Deployment
Failed' message :( Here is where it fails
Any help gratefully received!
