Disk (brick) failure on my stack
by Dominique D 23 Jun '21

23 Jun '21

yesterday I had a disk failure on my stack of 3 Ovirt 4.4.1 node on each server I have 3 Bricks (engine, data, vmstore) brick data 4X600Gig raid0. /dev/gluster_vg_sdb/gluster_lv_data mount /gluster_bricks/data brick engine 2X1TB raid1 /dev/gluster_vg_sdc/gluster_lv_engine mount /gluster_bricks/engine brick vmstore 2X1TB raid1 /dev/gluster_vg_sdc/gluster_lv_vmstore mount /gluster_bricks/vmstore Everything was configured by the gui (hyperconverge and hosted-engine) It is the raid0 of the 2nd server who broke. all VMs were automatically moved to the other two servers, I haven't lost any data. the host2 is now in maintenance mode. I am going to buy 4 new SSD disks to replace the 4 disks of the defective raid0. When I'm going to erase the faulty raid0 and create the new raid with the new disks on the raid controler, how do I add in ovirt so that they resynchronize with the other bricks data?

Is there a slack channel for oVirt project?
by Jesse Hu 23 Jun '21

23 Jun '21

Hi folks, Is there a slack channel for oVirt project? and is the #ovirt channel on irc.oftc.net server still active? I'd like to learn how oVirt project can be used for building IaaS platform, and whether oVirt community is active to provide support for questions. Thanks a lot.

Problems moving vm & templates between oVirt 4.3 & 4.4
by Guillaume Pavese 23 Jun '21

23 Jun '21

On ovirt 4.4.6, I created a VM and made a template from it. I would like to copy them to oVirt 4.3.7 & 4.3.10 DCs - I saw that Export Domain is deprecated. I tried exporting the VM & template to an Export Domain anyway but, after attaching the Export DOmain on my ovirt 4.3.7 DC, both VM and Template imports failed. The Template import failed immediately without any errors visible in the UI, The VM import failed with the message "General command validation failure." - I tried to do it through a Data Domains as recommended, but: If created on oVirt 4.4.6, I get a Format V5 DataDomain that my oVirt 4.3.7 refuses to import. If created first on the oVirt 4.3 DC, I get a Format V4 Domain. But then importing it on the oVirt 4.4 DC, I get the message: "Approving this operation will upgrade the Storage Domain format from 'V4' to 'V5'. Note that you will not be able to attach it back to an older Data Center." In "Administration > Providers" everything seems supported, from XEN / KVM and even VMware (we have used all three with some success). However oVirt is the obvious missing option... I still have to try "Export as OVA", is that the only supported way?

Import Ge0-Replicated Storage Domain fails
by simon＠justconnect.ie 22 Jun '21

22 Jun '21

Hi All, I have 2 independent Hyperconverged Sites/Data Centers. Site A has a GlusterFS Replica 3 + Arbiter Volume that is Storage Domain data2 This Volume is Geo-Replicated to a Replica 3 + Arbiter Volume at Site B called data2_bdt I have simulated a DR event and now want to import the Ge0-Replicated volume data2_bdt as a Storage Domain on Site B. Once imported I need to import the VMs on this volume to run in Site B. The Geo-Replication now works perfectly (thanks Strahil) but I haven't been able to import the Storage Domain. Please can someone point me in the right direction or documentation on how this can be achieved. Kind Regards Shimme...

importing vm's from storage pool from 4.1.6.2-1 in to 4.4.6 fails due to lingering snapshot configuration in source
by Charles Kozler 22 Jun '21

22 Jun '21

I know the subject is a bit wordy but let me try to explain I have a 4.1 installation that I am migrating to 4.4. I placed the storage domain into maintenance and then rsync'ed it to the storage I am using for 4.4. In 4.4 I import the domain and it comes in fine, however, when trying to import some VM's it fails because it says it cannot find a disk. The disk ID's I cannot find anywhere in 4.1 or 4.4 so I opened OVF_STORE after upgrading the pool in 4.4 and look at the ovf file for some of the VM's that are failing to import I see this in the ovf configuration file - <Section xsi:type="ovf:SnapshotsSection_Type"> <Snapshot ovf:id="e300fa3b-eee4-4b96-9103-45115081db57"> <Type>ACTIVE</Type> <Description>Active VM</Description> <CreationDate>2019/12/19 16:47:48</CreationDate> <Memory>07d3447c-c640-4163-9cf1-74ce126d702a,59b5cfdf-015b-0333-004b-000000000397,8c48ea33-dc34-403a-90d2-a3e78776404c,1757809b-9685-4315-a92e-3ea82dc6d8a8,94a2c2b3-e02e-4b05-80eb-6f4b7a9701e7,248a9fd1-61f0-4c5a-b6ab-4630d433c6fa</Memory> </Snapshot> </Section> </Content> </ovf:Envelope> These are the disk ID's I can see failing to import in engine.log I am aware that importing a VM cannot support snapshots and have found multiple mailing list posts around this, however, I do not have any snapshots visible in 4.1 UI. I also tried modifying OVF_STORE by untar'ing it and editing the ovf files directly, however, this does not work as it ends up overwritten by ovirt with the previous configuration Any ideas? As noted, I cannot see any snapshots listed in 4.1 source pool so I therefore cannot remove this stale configuration from the source and upon importing in to 4.4 it fails because it cannot find the disks I tried import partial and that still fails which to me seems like a bug because the idea of the import partial is to still register the VM even if it cant find disks I also tried scanning domain for disks and update OVF's in the UI and it does not help anything -- *Notice to Recipient*: https://www.fixflyer.com/disclaimer <https://www.fixflyer.com/disclaimer>

Grafana oVirt 4.4.4 Node install - Grafana Monitoring Portal not available
by simon＠justconnect.ie 21 Jun '21

21 Jun '21

Having installed oVirt 4.4.4 HCI 3 node cluster, the Grafana 'Monitoring Portal' was not visible on the Default page. It appears that Grafana is installed but not configured. I have checked a 4.4.3 environment and it is installed and running, so is this a bug with 4.4.4.7-1.el8? Any help would be appreciated.

Replacing hosted engine on Gluster
by Chris Adams 21 Jun '21

21 Jun '21

I've run oVirt on iSCSI storage for years, and I've had to replace the hosted engine a couple of times (upgrade from CentOS 6 to 7, then moving to new storage). I'm looking at oVirt on hyperconverged Gluster storage. I see pages about how to replace a host, but how do you replace the engine when needed? Is it possible to connect a new hosted engine to the existing Gluster storage? I'm just trying to understand all the differences of iSCSI vs. Gluster before deploying it for real; if there's info online that I missed, feel free to point me to it. Thanks! -- Chris Adams <cma(a)cmadams.net>
