Remove VM that failed being built from template
by Matthew.Stier＠fujitsu.com 21 Oct '20

21 Oct '20

oVirt 4.3.6 Attempted to build 10 VMs from a template, concurrently, and apparently overloaded the 1GB link to the iSCSI storage. I now have four VMs hung in the Locked connection on the display, and no means to cancel, remove them. The all have 'Failed to complete VM **** creation.' log entries, under Events. Any suggestions on how to address?

Need assistance in migrating between iSCSI arrays.
by Matthew.Stier＠fujitsu.com 21 Oct '20

21 Oct '20

To get a project going, I used an iSCSI SAN array of limited storage, while waiting to obtain, and make operational another iSCSI SAN of considerably more storage. I've attached the new iSCSI array to my cluster of hosts, attached a number of LUNs as additional storage domains, and move my collection of ISO and disk images to the new storage. I also detached and removed the old iSCSI storage domains I no longer need. I'm now down to the last two Storage Domains. The hosted_engine, and the last DATA domain, holding templates. Now the hard part reared its head. I need to completely detach the old iSCSI SAN array, which means I need to migrate the hosted-engine, and my small collection of templates, which I created on the old iSCSI array, to storage domains on the new iSCSI array. I'm looking for recommendations on how to do both. As to the details, I am running Oracle Linux Virtualization Manager 4.3.6, in hosted-engine mode, which means I am running oVirt 4.3.6, in hosted-engine mode. Note: I have configured the first three hosts in the cluster to support hosted-engine, so the hosted-engine can be moved around, for system maintenance.

[ANN] oVirt 4.4.3 Fifth Release Candidate is now available for testing
by Lev Veyde 21 Oct '20

21 Oct '20

oVirt 4.4.3 Fifth Release Candidate is now available for testing The oVirt Project is pleased to announce the availability of oVirt 4.4.3 Fifth Release Candidate for testing, as of October 16th, 2020. This update is the third in a series of stabilization updates to the 4.4 series. How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1 Note: Upgrading from 4.4.2 GA should not require re-doing these steps, if already performed while upgrading from 4.4.1 to 4.4.2 GA. These are only required to be done once. Due to Bug 1837864 <https://bugzilla.redhat.com/show_bug.cgi?id=1837864> - Host enter emergency mode after upgrading to latest build If you have your root file system on a multipath device on your hosts you should be aware that after upgrading from 4.4.1 to 4.4.3 you may get your host entering emergency mode. In order to prevent this be sure to upgrade oVirt Engine first, then on your hosts: 1. Remove the current lvm filter while still on 4.4.1, or in emergency mode (if rebooted). 2. Reboot. 3. Upgrade to 4.4.3 (redeploy in case of already being on 4.4.3). 4. Run vdsm-tool config-lvm-filter to confirm there is a new filter in place. 5. Only if not using oVirt Node: - run "dracut --force --add multipath” to rebuild initramfs with the correct filter configuration 6. Reboot.

How to clean up Storage Domain manually
by miguel.garcia＠toshibagcs.com 21 Oct '20

21 Oct '20

We have a problem in our cluster where the storage domain was consumed almost totally so we proceed to do a release space by deleting vms and templates that are not longer needed. Despite of removal we got the following eerror message removing some assets "The Storage Domain may be manually cleaned-up from possible leftover". Also this problem is triggered when new vms are created. How can we perform a manual clean-up in the storage domain?

Upgrade from ovirt-node-ng 4.4.1 to 4.4.2 fails with "Local storage domains were found on the same filesystem as / ! Please migrate the data to a new LV before upgrading, or you will lose the VMs"
by gantonjo-ovirt＠yahoo.com 20 Oct '20

20 Oct '20

So, we have a cluster of 3 servers running oVirt Node 4.4.1. Now we are attempting to upgrade it to latest version, 4.4.2, but it fails as shown below. Problem is that the Storage domains listed are all located on an external iSCSI SAN. The Storage Domains were created in another cluster we had (oVirt Node 4.3 based) and detached from the old cluster and imported successfully into the new cluster through the oVirt Management interface. As I understand, oVirt itself has created the mount points under /rhev/data-center/mnt/blockSD/ for each of the iSCSI domains, and as such they are not really storaged domains on the / filesystem. I do believe the solution to the mentioned BugZilla bug has caused a new bug, but I may be wrong. I cannot see what we have done wrong when importing these storage domains to the cluster (well, actually, some were freshly created in this cluster, thus fully managed by oVirt 4.4 manager interface). What can we do to proceed in upgrading the hosts to latest oVirt Node?

How to make oVirt + GlusterFS bulletproof
by Jarosław Prokopowski 16 Oct '20

16 Oct '20

Hi Guys, I had a situation 2 times that due to unexpected power outage something went wrong and VMs on glusterfs where not recoverable. Gluster heal did not help and I could not start the VMs any more. Is there a way to make such setup bulletproof? Does it matter which volume type I choose - raw or qcow2? Or thin provision versus reallocated? Any other advise?

Latest ManagedBlockDevice documentation
by Michael Thomas 15 Oct '20

15 Oct '20

I'm looking for the latest documentation for setting up a Managed Block Device storage domain so that I can move some of my VM images to ceph rbd. I found this: https://ovirt.org/develop/release-management/features/storage/cinderlib-int… ...but it has a big note at the top that it is "...not user documentation and should not be treated as such." The oVirt administration guide[1] does not talk about managed block devices. I've found a few mailing list threads that discuss people setting up a Managed Block Device with ceph, but didn't see any links to documentation steps that folks were following. Is the Managed Block Storage domain a supported feature in oVirt 4.4.2, and if so, where is the documentation for using it? --Mike [1]ovirt.org/documentation/administration_guide/
