Ovirt 4.2.8.. Possible bug?
by matteo fedeli 25 Feb '19

25 Feb '19

Hi considering that the deploy with 4.2.7.8 failed I try to reinstall ovirt to version 4.2.8 and there are appened two strange things. During the volume step if i choose jbod mode in the deploy conf remain raid6 type... Why? To solve I have only tried to editing manually the file at line about volume type and the deploy stuck on creating physical volume... this is my conf file: (I used 3 HDDs 500GB each, node,engine + vmstore and data) #gdeploy configuration generated by cockpit-gluster plugin [hosts] kansas.planet.bn germany.planet.bn singapore.planet.bn [script1:kansas.planet.bn] action=execute

Re: Ovirt Glusterfs

I have done some testing and it seems that storhaug + ctdb + nfs-ganesha is showing decent performance in a 3 node hyperconverged setup. Fuse mounts are hitting some kind of limit when mounting gluster -3.12.15 volumes. Best Regards, Strahil Nikolov

Creating new VM
by Yujin Boby 24 Feb '19

24 Feb '19

I installed oVirt, when i try to create a new VM, it says This host is managed by a virtualization manager, so creation of new VM from this host is not possible. https://imgur.com/a/hpqV6ML Any idea why i am getting this error ? Do i need more than 1 server to create Virtual machines ? Like adding a node ?

How to recreate Ovirt CA from scratch
by Giorgio Biacchi 24 Feb '19

24 Feb '19

Hi list, during our datacenter lifetime many things changed. We moved the engine twice on different hosts with, of course, different FQDNs, and many other changes. Now we are stuck with an error when we try to upload an image to a data domain. The error is somehow bound to a failure to validate the ovirt-imageio-proxy certificate and, since the current root CA certificate is still signed with sha1WithRSAEncryption we'd like to regenerate the whole CA. That's the steps we've done.. without success... 1) Make a tar.gz of the /etc/pki/ovirt-engine as backup 2) Create a new CA cert using the same private key: openssl req -key /etc/pki/ovirt-engine/private/ca.pem -new -x509 -days 3650 -sha256 -extensions v3_ca -out newca.cert.pem 3) Put the new CA cert in place mv ca.pem ca.pem.orig.20190219;mv newca.cert.pem ca.pem 4) Resign all the other certs names="engine apache websocket-proxy jboss imageio-proxy" for name in $names; do subject="$( openssl \ x509 \ -in /etc/pki/ovirt-engine/certs/"${name}".cer \ -noout \ -subject \ | sed \ 's;subject= $.*$;\1;' \ )" /usr/share/ovirt-engine/bin/pki-enroll-pkcs12.sh \ --name="${name}" \ --password=mypass \ --subject="${subject}" \ --keep-key done 5) Restart all the services systemctl restart httpd systemctl restart ovirt-engine systemctl restart ovirt-websocket-proxy systemctl restart ovirt-imageio-proxy The following step was to take the backup at 1) and fall back to the initial state because nothing worked as expected. There's any documented procedure about how to recreate Ovirt CA from scratch??

Hi Guys, I am trying to install oVirt node on a physical machine. Once selected the option to install oVirt 4.3 it give a screen "dracut-initqueue time out And then get into emergency mode & gives dracut cmd line. if I exit the command line, it continue boot into the installation window. However it gives a message "Kickstart file /run/install/ks.config is missing" (Pane is dead). Tried the same on vmware, it boot fine & am able to install it. Can someone tell me how could I fix this?

Design question: one big NFS share or several smaller ones?
by Markus Schaufler 22 Feb '19

22 Feb '19

Hi all, I've got a design question: Are there any best practices regarding NFS datastores especially datastore sizing? Should I use one big NFS datastore and expand it on demand or should the size not exceed a certain limit and start with a new NFS datastore? Are there any other configuration considerations (NFS v3 or v4(.1) and mounting options)?
