This one shows if a setting differs from the defaults. As I don't know the default (you can see it with gluster volume set help), you can check via gluster volume get <VOLUME> cluster.lookup-optimize. best Regards,Strahil Nikolov On Wed, Apr 6, 2022 at 16:50, Mohamed Roushdy<mohamedroushdy(a)peopleintouch.com> wrote:  Well, I think it’s not configured.

The thing is, we had data lose disaster last month, and that's why we've decided to deploy a cmmpletely new environment for taht pirpose, and let me tell you what happened. We are using Ovirt 4.1 with Gluster 3.8 for our production, and the cluster contains five hosts, three of them are storage servers. I've added two more hosts, and manually via CLI (as I couldn't do this via GUI) created a new brick on one of the newely added nodes,and expanded the volume with the parameter "replica = 4 as it was refused to expand without setting the replica count. The action was successful for both the engine vol, and the data vol, however, few minutes later we've found that the disk sizes (images) of the existing VMs got shrunk and lost all of the data, and we had to recover from backup.. We can't afford another downtime (another disaster I mean), that's why I'm so maticulous about what to do next, so, is there a good guide around for the architecure and sizing?

Storage Design Question - GlusterFS
by mohamedroushdy＠peopleintouch.com 06 Apr '22

06 Apr '22

Hello, we are designing a new production cluster, and I have to questsions about GlusterFS please: 1- this quote from the documentation os not clear to me " Creating additional data domains in the same data center as the self-hosted engine storage domain is highly recommended. If you deploy the self-hosted engine in a data center with only one active data storage domain, and that storage domain is corrupted, you will not be able to add new storage domains or remove the corrupted storage domain; you will have to redeploy the self-hosted engine." Does this mean that we should have more than one "Data" domain? or here this paragraph is talking about sharing a single domain for both the hosted-engine and VMs? 2- the documentation mentioned that Replica 1 or Replica 3 are only supported, but is this only for the hosted-engine volume? or also for Data volumes? so the max is only 3? and waht if I wanted to expand capacity later? Thank you,

Enroll Host Certificate
by dlotarev＠yahoo.com 05 Apr '22

05 Apr '22

Hi there! I have a problem to enroll host certificate. The steps that I took: 1) Move host to maintenance mode (all VMs transferred to another host including HE VM) 2) Enroll certificate via web interface without errors 3) Exit from maintenance mode (transferred all VMs back including HE VM) 4) Restart ovirt-engine service But my problem that after 6 hours i get message from oVirt engine notifier that my certificate expired soon. I know that my oVirt installation is old (4.1.9), but what can i do with that? Maybe i missed something. I didn't reboot the host after renewing the certificate Thank you for any advice!

When I try to run "hosted-engine --deploy --restore-from-file=backup.bck" on the same machine with a fresh install of ovirt node 4.3 I get this error after some minutes: [ ERROR ] fatal: [localhost -> ovirt.*mydomain.com*]: FAILED! => {"changed": false, "elapsed": 185, "msg": "timed out waiting for ping module test success: Failed to connect to the host via ssh: @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@\r\n@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @\r\n@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@\r\nIT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!\r\nSomeone could be eavesdropping on you right now (man-in-the-middle attack)!\r\nIt is also possible that a host key has just been changed.\r\nThe fingerprint for the ECDSA key sent by the remote host is\nSHA256:aer7BMZyKHhfzMXX4pzVULHN7OwSSNDrCuOyvdmG8sQ.\r\nPlease contact your system administrator.\r\nAdd correct host key in /dev/null to get rid of this message.\r\nOffending ED25519 key in /var/lib/sss/pubconf/known_hosts:6\r\nPassword authentication is disabled to avoid man-in-the-middle attacks.\r\nKeyboard-interactive authentication is disabled to avoid man-in-the-middle attacks.\r\nPermission denied (publickey,gssapi-keyex,gssapi-with-mic,password)."} I can't find anything in the docs about this problem. I already removed all the entries in /var/lib/sss/pubconf/known_hosts on my ovirt host machine. But that didn't change anything. Is their something wrong with the backup. At the moment I have 2 other hosts running my VM's but no ovirt manager.

Failed to start service jboss.deployment.subunit."engine.ear"."webadmin.war".STRUCTURE Ovirt 4.4.10 Self-hosted engine

I'm trying to deploy a new ovirt 4.4.10 self-hosted engine. Whenever I try to access the server via a web browser I get 404 - Not Found. In /var/log/ovirt-engine/server.log I see Failed to start service jboss.deployment.subunit."engine.ear"."webadmin.war".STRUCTURE due to a java.io.FileNotFoundException for /var/lib/ovirt-engine/jboss_runtime/tmp/vfs/deployment/deployment38ca8fb55a7d2674/gwt-servlet.jar-ab669e949f887030/gwt-servlet.jar. Inside /var/lib/ovirt-engine/jboss_runtime/tmp/vfs/deployment/deployment38ca8fb55a7d2674/, I do not have the gwt-servlet.jar-ab669e949f887030 dir. I can create it and copy gwt-servlet.jar to it and set the proper ownership and permissions, but then I am not sure how to restart jboss. I am not sure what is happening that would prevent the gwt-servlet.jar dir from being created inside the /var/lib/ovirt-engine/jboss_runtime/tmp/vfs/deployment/ dir. I can see bll.jar, 4 branding.jar dirs, docs.jar, enginesso.jar, scheduler.jar, services.jar, vdsbroker.ja r, and welcome.jar dirs inside /var/lib/ovirt-engine/jboss_runtime/tmp/vfs/deployment/deployment38ca8fb55a7d2674 but no gwt-servlet.jar dir unless I make it myself.

Network filters in oVirt : zero-trust, IP and port filtering
by ravi k 01 Apr '22

01 Apr '22

Good people of the community, Hope you are all doing well. We are exploring the network filters in oVirt to check if we can implement a zero-trust model at the network level. The intention is to have a filter which takes two parameters, IP and PORT. After that there will be a 'deny all' rule. We realized that none of the default network filters offer such a functionality and the only option is to write a custom filter. Why don't we have such a filter in libvirt and thereby in oVirt? Someone would've already thought about such a use case. So I was thinking maybe network filters aren't meant to be used for implementing such functionalities like zero-trust? Also what are some practical use cases of the default filters that are provided? I was able to understand and use the clean-traffic and clean-traffic-gateway. Regards, ravi
