Discard a snapshot
by Mitja Mihelič 15 Mar '19

15 Mar '19

Hi! We have run into a problem migrating a VM's disk. While doing a live disk migration it all went well until "Removing Snapshot Auto-generated for Live Storage Migration". The operation started and got stuck in the "Preparing to merge" stage. The task was visible as an async task for a couple of days, then dissapeared. The snapshot named "Auto-generated for Live Storage Migration" still exists. If we try to start the VM it produces the following error: VM VM_NAME_HERE is down with error. Exit message: Bad volume specification {u'index': 0, u'domainID': u'47ee9bde-4f18-43c2-9383-0d30a27d1ae7', 'reqsize': '0', u'format': u'cow', u'bootOrder': u'1', u'address': {u'function': u'0x0', u'bus': u'0x00', u'domain': u'0x0000', u'type': u'pci', u'slot': u'0x05'}, u'volumeID': u'3b0184b7-5c5d-4669-8b3a-04880883118a', 'apparentsize': '19193135104', u'imageID': u'35599677-250a-4586-9db1-4df8f3291164', u'discard': False, u'specParams': {}, u'readonly': u'false', u'iface': u'virtio', u'optional': u'false', u'deviceId': u'35599677-250a-4586-9db1-4df8f3291164', 'truesize': '19193135104', u'poolID': u'35628205-9fa3-41de-b914-84f9adb633e4', u'device': u'disk', u'shared': u'false', u'propagateErrors': u'off', u'type': u'disk'}. From what I understand the data access path is snapshot->"disk before snapshot". And since the snapshot is corrupted it cannot be accessed and the whole VM start process fails. I believe that the disk before the snapshot was made is still intact. How can we discard the whole snapshot so that are left only with the state before the snapshot was made? We can afford to lose the data in the snapshot. Best regards, Mitja

Migrating VMs from ovirt-4.1.1 to ovirt-4.2.8
by Wood Peter 15 Mar '19

15 Mar '19

Hi, I need to migrate a few dozen VMs from ovirt-4.1.1 to ovirt-4.2.8. I did a few following this procedure: VMs export -> Detach Export domain -> Attach Export to new ovirt -> Import VMs Importing from VMware is one step only process. All I have to do is select VMware for Source in the Import page and then import the VMs I need. I feel like I'm missing something. Is there a way to import VMs from another ovirt deployment similar to import from VMware i.e. without going through Export storage domain? Thank you, -- Peter

hosted-engine --deploy fails on iSCSI while trying to connect to retrieved ipv6 address, even while forcing ipv4 with --4
by Guillaume Pavese 15 Mar '19

I try to deploy hosted-engine 4.3.2-rc2 on iSCSI I put a ipv4 portal address and targets get discovered. However they are are returned by the Synology hosts with both ipv4 and ipv6 adresses.

upgrading failed from 4.2 to 4.3
by Abhishek Sahni 15 Mar '19

15 Mar '19

Hello Users, I am trying to upgrade ovirt-engine running on bare metal, following below guide, https://ovirt.org/release/4.3.0/ and it is getting failed every time with the below errors, engine-setup ============================ [ INFO ] Stage: Setup validation During execution engine service will be stopped (OK, Cancel) [OK]: [ ERROR ] It seems that you are running your engine inside of the hosted-engine VM and are not in "Global Maintenance" mode. In that case you should put the system into the "Global Maintenance" mode before running engine-setup, or the hosted-engine HA agent might kill the machine, which might corrupt your data. [ ERROR ] Failed to execute stage 'Setup validation': Hosted Engine setup detected, but Global Maintenance is not set.

Check in API if host is in state "reconfiguring networks"
by Eduardo Mayoral 14 Mar '19

14 Mar '19

Hi, I am writing some provisioning scripts using the python API in which I add a number of hosts to an ovirt engine. To minimize the time the script takes, I would like to call host_service.setup_network() and host_service.commit_net_config() for each host with async=True and then get into a loop checking every few seconds for the status of the hosts until all of them have finished (so I can go on with another task such as configuring storage). I was able to do something similar for the install phase checking if host.status equals HostStatus.MAINTENANCE , but I cannot find in the documentation how to check when a host is in status "reconfiguring network". The web interface shows this, so surely there must be a way, but I have not managed to find it in the API documentation. Could somebody help? Thanks in advance! -- Eduardo Mayoral Jimeno Systems engineer, platform department. Arsys Internet. emayoral(a)arsys.es - +34 941 620 105 - ext 2153

Re: Migrate HE between ISCSI storages

If you have the will, would you create a short but detailed instruction ? I think that it will be nice to have your experience documented in the ovirt docs.

Re: Migrate HE between ISCSI storages
by Strahil 14 Mar '19

I don't think you can do it from the UI. The problems is that there are several tar files that contain the location of the disks and that is being read by ovirt-ha-agent on all hosts. I think that someone with deeper experience can get involved. From System Administrator perspective I would just swap the target names (old gets new target name, new one gets old target name), but this is only if the iSCSI target is not used for anything else.

Hi, everyone, there is a VM in the HostedEngine virtual machine that has been paused due to a storage I/O error, but engine manager services are normal, what is the problem?
