Fwd: Re: Can ovirt-node support multiple network cards ？
by Roberto Nunin 22 Oct '19

22 Oct '19

If I've understood clearly, your goal is to have two physical network interfaces connected to one logical network in ovirt-engine. If this is the case, you can use bonding/teaming physical interfaces into one and then connect that aggregation to the ovirt-engine logical network. Moreover, as Jeremy stated, you can use that aggregated physical interfaces to transfer VLANs, taking advantages on redundancy/resilience and configuration flexibility.

Help/guidelines/ideas on how to create new hosted-engine on final server with old config
by Lars Bækmark 21 Oct '19

21 Oct '19

I'm looking for guidelines/ideas for moving/migrating/Hosted-engine from the initial install with local storage, to the "Final" server. Initial it was a "Test" to see if this will work or not, but this has now become the production, where the initial host named "ovirt" that is hosting the hosted-engine on local storage is "just" doing that. My hosted-engine is called "ovirtmgr" and I created a new host to run Virtual machines called "Hermod" - getting better in the naming thing, right? This test was so successful that I converted the old Xen/Oracle based host to CentOS 7 - the same as host Ovirt and Hermod: Linux hermod 3.10.0-1062.1.1.el7.x86_64 #1 SMP Fri Sep 13 22:55:44 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux <https://www.facebook.com/linux.lanka?fref=gs&__tn__=%2CdK-R-R&eid=ARDadyp9k…> Linux fernis 3.10.0-1062.el7.x86_64 #1 SMP Wed Aug 7 18:08:02 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux oVirt version is: 4.3.5.4-1.el7 I want to move the hosted-engine to Fenris and at the same time use a NFS share for that. I can shut the whole setup down, as long as it runs again in daytime. I do know that I should have started with the hosted-engine in the correct place, but that's not the case anymore. There are eleven VM’s in total Can anyone suggest a plan on how to move/create a new hosted-engine on my server Fenris? The history of the old server is not important, I just want the hosted-engine on fenris using NFS share I did find some sugesting on the web, but they all look quite complicated: https://www.ovirt.org/…/engine/migrate-to-hosted-engine.html <https://l.facebook.com/l.php?u=https%3A%2F%2Fwww.ovirt.org%2Fdevelop%2Fdeve…> I just love the product!

Re: improve file operation speed in HCI
by Strahil 18 Oct '19

If you seek performance, then set tuned-adm profile in the VM to 'throughput-performance' and scheduler either 'noop' or 'none' (depends if multi queue is enabled). Usually, if yhou crete the gluster cluster via cockpit and then install the hosted engine via cockpit again - all options on your gluster volumes are the most optimal you need.

What is your I/O scheduler and tuned-adm profile in the VM. RedHat based VMs use deadline which prioritizes reads before writes -> you can use 'noop' or 'none'. For profile, you can use high-performance.

I am running stock optimize for virt store volume settings currently and am wondering what if any improvements I can make for VM write speed and more specifically anything I can tune to increase performance of small file operations such as copying, untar, npm installs etc. For some context, I'm seeing ~50MB/s write speeds inner VM with: dd if=/dev/zero of=./test bs=512k count=2048 oflag=direct -- I am not sure how this compares to other HCI setups, I feel like it should be higher with SSD backed storage.

For example my gluster network IP is 10.10.10.1/24 and the /etc/hosts entry is: 10.10.10.1 gluster1.localdomain gluster1 Then I did 'gluster volume replace-brick ovirt1:/gluster_bricks/data/data gluster1:/gluster_bricks/data/data commit' So you use a hostname that is resolved either by DNS or /etc/hosts to your desired IP.

The reset-brick and replace-brick affects only one brick and notifies the gluster cluster that a new hostname:/brick_path is being used. Of course, you need a hostname that resolves to the IP that is on the storage network. WARNING: Ensure that no heals are pending as the commands are wiping the brick and data there is lost.

[oVirt HC] Gluster traffic still flows on mgmt even after choosing a different Gluster nw
by Stefano Stagnaro 17 Oct '19

17 Oct '19

Hi, I've deployed an oVirt HC starting with latest oVirt Node 4.3.6; this is my simple network plan (FQDNs only resolves the front-end addresses): front-end back-end engine.ovirt 192.168.110.10 node1.ovirt 192.168.110.11 192.168.210.11 node2.ovirt 192.168.110.12 192.168.210.12 node3.ovirt 192.168.110.13 192.168.210.13 at the end I followed the RHHI-V 1.6 Deployment Guide where, at chapter 9 [1], it suggests to create a logical network for Gluster traffic. Now I can see, indeed, back-end addresses added in the address pool: [root@node1 ~]# gluster peer status Number of Peers: 2 Hostname: node3.ovirt Uuid: 3fe33e8b-d073-4d7a-8bda-441c42317c92 State: Peer in Cluster (Connected) Other names: 192.168.210.13 Hostname: node2.ovirt Uuid: a95a9233-203d-4280-92b9-04217fa338d8 State: Peer in Cluster (Connected) Other names: 192.168.210.12 The problem is that the Gluster traffic seems still to flow on the management interfaces: [root@node1 ~]# tcpdump -i ovirtmgmt portrange 49152-49664 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on ovirtmgmt, link-type EN10MB (Ethernet), capture size 262144 bytes 14:04:58.746574 IP node2.ovirt.49129 > node1.ovirt.49153: Flags [.], ack 484303246, win 18338, options [nop,nop,TS val 6760049 ecr 6760932], length 0 14:04:58.753050 IP node2.ovirt.49131 > node1.ovirt.49152: Flags [P.], seq 2507489191:2507489347, ack 2889633200, win 20874, options [nop,nop,TS val 6760055 ecr 6757892], length 156 14:04:58.753131 IP node2.ovirt.49131 > node1.ovirt.49152: Flags [P.], seq 156:312, ack 1, win 20874, options [nop,nop,TS val 6760055 ecr 6757892], length 156 14:04:58.753142 IP node2.ovirt.49131 > node1.ovirt.49152: Flags [P.], seq 312:468, ack 1, win 20874, options [nop,nop,TS val 6760055 ecr 6757892], length 156 14:04:58.753148 IP node2.ovirt.49131 > node1.ovirt.49152: Flags [P.], seq 468:624, ack 1, win 20874, options [nop,nop,TS val 6760055 ecr 6757892], length 156 14:04:58.753203 IP node2.ovirt.49131 > node1.ovirt.49152: Flags [P.], seq 624:780, ack 1, win 20874, options [nop,nop,TS val 6760055 ecr 6757892], length 156 14:04:58.753216 IP node2.ovirt.49131 > node1.ovirt.49152: Flags [P.], seq 780:936, ack 1, win 20874, options [nop,nop,TS val 6760055 ecr 6757892], length 156 14:04:58.753231 IP node1.ovirt.49152 > node2.ovirt.49131: Flags [.], ack 936, win 15566, options [nop,nop,TS val 6760978 ecr 6760055], length 0 ... and no yet to the eth1 I dedicated to gluster: [root@node1 ~]# tcpdump -i eth1 portrange 49152-49664 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth1, link-type EN10MB (Ethernet), capture size 262144 bytes What am I missing here?

Check why the sanlock.service reports no pid. Also check the logs of the broker and agent located at /var/log/ovirt-hosted-engine-ha You might have to increase the verbosity of the broker and agent.

I have researched, however I have not been able to find a solution. thanks, Adrian

ovirt and jackson security

When I launch ovirt 4.3.6, I see in the command line of the ovirt-engine: -Djackson.deserialization.whitelist.packages=org,com,java,javax That whitelist almost everything. Isn't that dangerous ? When I read this: https://medium.com/@cowtowncoder/on-jackson-cves-dont-panic-here-is-what-yo… I think the white list should be as small as possible.
