Re: Do I need to use self hosted engine with a GlusterFs three node setup

You don't need to host the engine on the gluster cluster. I know people you have hosted the engine on a bare metal (pacemaker cluster) , so feel free to experiment. The only requirement is that tge engine needs to be able to communicate with the hosts (I'm not sure if layer 2 connectivity is necessary).

External networks issue after upgrading to 4.3.6
by ada per 12 Nov '19

12 Nov '19

After upgrading to the latest stable version the external networks lost all functionality. Under providers-->ovn-network-provider the test runs successfully. But when im creating an external provider network, attaching it to a router as a LAN setting up dhcp lease it is not reachable from other VMs in the same network. Hosts and hosted engine can't seem to ping it either. I tried disabling firewalls on both hosted engines, VMs and host and still nothing. When configuring Logical networks or VLANs they work perfectly tje one problem is the external networks. I have another environment running on a previous version of ovirt and it works perfectly there. I think its a bug. Thanks for your help

Re: Migrate VM from oVirt to oVirt
by Strahil 12 Nov '19

12 Nov '19

You will need a storage that will be your 'USB stick' . For example you can attach NFS-based storage domain, migrate the disks of the VM to that storage. Then power off that VM, set the storage to maintenance and then detach it from first oVirt engine. Then you attach and activate that NFS storage in your new oVirt engine. After Activation, there will be an 'Import VMs/templates' tab . Click on it and import the VM in a cluster. Last step is to migrate your VM's disks from that NFS to their permanent storage.

SHE with multipath on multiple iSCSI targets
by Francesco Castellano 12 Nov '19

12 Nov '19

Dear sirs, we're trying to install an SHE oVirt 4.3.6 using an iSCSI SAN that provides us multiple targets (8) over 4 different portals. Following 5.1 of "RHV installation using Cockpit" we set up iscsi and multipath ahead with a 90GB LUN to be used for the engine VM. Unfortunately, even if the node OS sees correctly the LUN, e.g.: # multipath -ll > 36000d31004235a000000000000000018 dm-34 COMPELNT,Compellent Vol > size=90G features='1 queue_if_no_path' hwhandler='0' wp=rw > `-+- policy='service-time 0' prio=1 status=active > |- 16:0:0:3 sdu 65:64 active ready running > |- 24:0:0:3 sdt 65:48 active ready running > |- 17:0:0:3 sds 65:32 active ready running > |- 25:0:0:3 sdv 65:80 active ready running > |- 15:0:0:3 sdx 65:112 active ready running > |- 29:0:0:3 sdw 65:96 active ready running > |- 28:0:0:3 sdy 65:128 active ready running > |- 20:0:0:3 sdz 65:144 active ready running > `- 21:0:0:3 sdaa 65:160 active ready running # lsscsi -ist | grep 36000d31004235a000000000000000018 > [15:0:0:3] disk iqn.2002-03.com.compellent:5000d31004235a43,t,0x0 > /dev/sdx 36000d31004235a000000000000000018 96.6GB > [16:0:0:3] disk iqn.2002-03.com.compellent:5000d31004235a43,t,0x0 > /dev/sdu 36000d31004235a000000000000000018 96.6GB > [17:0:0:3] disk iqn.2002-03.com.compellent:5000d31004235a44,t,0x0 > /dev/sds 36000d31004235a000000000000000018 96.6GB > [20:0:0:3] disk iqn.2002-03.com.compellent:5000d31004235243,t,0x0 > /dev/sdz 36000d31004235a000000000000000018 96.6GB > [21:0:0:3] disk iqn.2002-03.com.compellent:5000d31004235244,t,0x0 > /dev/sdaa 36000d31004235a000000000000000018 96.6GB > [24:0:0:3] disk iqn.2002-03.com.compellent:5000d31004235a48,t,0x0 > /dev/sdt 36000d31004235a000000000000000018 96.6GB > [25:0:0:3] disk iqn.2002-03.com.compellent:5000d31004235a49,t,0x0 > /dev/sdv 36000d31004235a000000000000000018 96.6GB > [28:0:0:3] disk iqn.2002-03.com.compellent:5000d31004235248,t,0x0 > /dev/sdy 36000d31004235a000000000000000018 96.6GB > [29:0:0:3] disk iqn.2002-03.com.compellent:5000d31004235249,t,0x0 > /dev/sdw 36000d31004235a000000000000000018 96.6GB > # iscsiadm -m session | grep -E '[a2]4[3489]' | sort -k 3.8 > tcp: [1] 10.201.204.10:3260,0 iqn.2002-03.com.compellent:5000d31004235a43 > (non-flash) > tcp: [2] 10.201.204.10:3260,0 iqn.2002-03.com.compellent:5000d31004235a43 > (non-flash) > tcp: [3] 10.201.204.10:3260,0 iqn.2002-03.com.compellent:5000d31004235a44 > (non-flash) > tcp: [6] 10.201.204.20:3260,0 iqn.2002-03.com.compellent:5000d31004235243 > (non-flash) > tcp: [7] 10.201.204.20:3260,0 iqn.2002-03.com.compellent:5000d31004235244 > (non-flash) > tcp: [10] 10.201.205.10:3260,0 > iqn.2002-03.com.compellent:5000d31004235a48 (non-flash) > tcp: [11] 10.201.205.10:3260,0 > iqn.2002-03.com.compellent:5000d31004235a49 (non-flash) > tcp: [14] 10.201.205.20:3260,0 > iqn.2002-03.com.compellent:5000d31004235248 (non-flash) > tcp: [15] 10.201.205.20:3260,0 > iqn.2002-03.com.compellent:5000d31004235249 (non-flash) > during the engine deploy neither via cockpit nor with "hosted-engine --deploy" it was able to see any LUN. Having a lot of portals (4) and each having 4 targets (two of which being independents path to the LUN), we chose a portal to discover, it proposed us 4 targets, and we had to choose a target to log in, but in the end, no LUN was proposed. After a few attempts, we found that, if we logged out from any targets (and clean up the open-iscsi database), after the login in an appropriate target, the installer proposed us the LUN, and we successfully deployed the SHE. But unfortunately, such an installation doesn't track effectively all the 8 paths over 8 different targets, but just the one chosen during the installation (this is different, for example, with respect to other LUNs for data domains that we attached afterwards). Thus we miss the HA we aimed to for the engine data domain. I said this, because when I ask for /ovirt-engine/api/storagedomains, whilst a second LUN has 8 children with different targets below storage_domain/${another data domain}/storage/volume_group/logical_units/logical_unit/, for the hosted_storage I just have one. My questions are: a) is there a way to add the other targets/paths consistently (even through the REST interface)? b) is there another installation, or recovery, procedure to get the engine data domain in high availability on our iSCSI topology? Thank you so much for your suggestions, they are really appreciated, Best regards, Francesco Castellano

Quick question regarding FQDN
by Christian Reiss 11 Nov '19

11 Nov '19

Hey folks, for production use quality it is recommended to have backend (storage) and front end seperated. Let' assume: - 85.0.0.0/24 public IP block - 10.100.0.0/24 private IPs for DC internal usage - 10.200.0.0/24 private IPs for storage only LAN and running, as per recommendation 3 nodes: - node01: - fqdn: node01.dc-example.com - fqdn storage: node02.storage.example.com - no public IP - 10.100.0.1 primary IP - 10.200.0.1 storage IP - node02: - fqdn: node02.dc-example.com - fqdn storage: node02.storage.example.com - no public IP - 10.100.0.2 primary IP - 10.200.0.2 storage IP - node03: - fqdn: node03.dc-example.com - fqdn storage: node02.storage.example.com - no public IP - 10.100.0.3 primary IP - 10.200.0.3 storage IP The storage network is its own physical network with 10gig that only connects those three servers. How can I specify which IP to use for storage, which for frontend traffic? I am assuming this as the controller and all admins should be able to reach the nodes via frontend, which is not the storage one. Okay, I am lost. Whats the real solution here? Or is "frontend" no-ip, just VM traffic and "backend" is the 10gig storage "Only" where all the FQDN reside?

I want to configure an web server
by Istiaque Islam 11 Nov '19

11 Nov '19

Hi there, I have installed oVirt on a server and related ISO and Data domains. I can create Virtual Machines and that machine get access to internet to download things. What I want to do now : 1. create an web server using centos and access that webserver from anywhere with internet connection 2. Then I shall configure a domain name for that webserver hosted in oVirt Virtual Machine. My Question : How to configure the virtual machine in oVirt so that when I enter my specified domain name/IP it will hit that particular virtual machine? As it is a virtual machine, it will not get any public IP, so how should i configure the virtual machine set up so that it can be used as an web server. Thanks in advance. -- With Regards, *Mohammed Istiaque Islam* *Contact no *: *+8801745723593* Email : jisan6347(a)gmail.com LinkedIn Profile : Profile_Linkedin_Istiaque <http://www.linkedin.com/in/mohammed-istiaque-islam-59541866>
