Hi I just want to know if there is any way I can disable the yum looking for updates on the internet on the node? Please help me out here.

planned jenkins and resources downtime
by Evgheni Dereveanchin 29 Nov '16

29 Nov '16

Hi everyone, As part of a planned maintenance window I am going to apply OS updates and reboot the Jenkins master along with our resources file server. Affected services: jenkins.ovirt.org resources.ovirt.org This means that no new jobs will be started on the Jenkins and our repositories will be unavailable for a short period of time. I will follow up on this email once all services are back up and running. Regards, Evgheni Dereveanchin

How to migrate Self Hosted Engine
by Gianluca Cecchi 29 Nov '16

29 Nov '16

Hello, I have an Hyperconverged gluster cluster with SEH and 3 hosts born in 4.0.5. The installation was done starting from ovirt01 (named hosted_engine_1 in webadmin gui) and then deploying two more hosts: ovirt02 and ovirt03 from web admin gui itself. All seems ok. I can migrate a normal VM from one host to another one and nice that I don't loose console now. But if I try from webadmin gui to migrate the self hosted engine I get this message: https://drive.google.com/file/d/0BwoPbcrMv8mvY3pURVRkX0p4OW8/view?usp=shari… Is this because the only way to migrate engine is to put its hosting host to maintenance or is there anything wrong? I don't understand the message: The host ovirt02.localdomain.local did not satisfy internal filter HA because it is not a Hosted Engine host.. some commands executed on hosted_engine_1 (ovirt01): [root@ovirt01 ~]# vdsClient -s 0 glusterHostsList {'hosts': [{'hostname': '10.10.100.102/24', 'status': 'CONNECTED', 'uuid': 'e9717281-a356-42aa-a579-a4647a29a0bc'}, {'hostname':

deleted then rebuilt node still showing up in status
by Charles Kozler 29 Nov '16

29 Nov '16

I put the node in to maint. mode, removed all VMs from it, and then deleted it from the web UI. I then rebuilt it with hosted-engine --deploy and indicated it is now node 4 (was previously #3) and now in --vm-status it is still showing up as stale data What can I do? In fact, it looks like ovirt thinks its still in maint mode I am presuming because I used the same host name? --== Host 1 status ==-- Status up-to-date : True Hostname : node03 Host ID : 1 Engine status : {"reason": "vm not running on this host", "health": "bad", "vm": "down", "detail": "unknown"} Score : 3400 stopped : False Local maintenance : False crc32 : 87e08365 Host timestamp : 3270683 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=3270683 (Tue Nov 29 08:43:52 2016) host-id=1 score=3400 maintenance=False state=EngineDown stopped=False --== Host 2 status ==-- Status up-to-date : True Hostname : node01 Host ID : 2 Engine status : {"health": "good", "vm": "up", "detail": "up"} Score : 3400 stopped : False Local maintenance : False crc32 : 66c7154a Host timestamp : 3267326 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=3267326 (Tue Nov 29 08:43:44 2016) host-id=2 score=3400 maintenance=False state=EngineUp stopped=False --== Host 3 status ==-- Status up-to-date : False Hostname : node02 Host ID : 3 Engine status : unknown stale-data Score : 0 stopped : False Local maintenance : True crc32 : 040b4192 Host timestamp : 211984 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=211984 (Mon Nov 28 20:28:06 2016) host-id=3 score=0 maintenance=True state=LocalMaintenance stopped=False --== Host 4 status ==-- Status up-to-date : True Hostname : node02 Host ID : 4 Engine status : {"reason": "vm not running on this host", "health": "bad", "vm": "down", "detail": "unknown"} Score : 0 stopped : False Local maintenance : True crc32 : 6aa7d568 Host timestamp : 43683 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=43683 (Tue Nov 29 08:44:11 2016) host-id=4 score=0 maintenance=True state=LocalMaintenance stopped=False In web UI it does not show the node (node02 / Host ID #4) as being in maint. mode

can't import vm from KVM host
by Nelson Lameiras 29 Nov '16

29 Nov '16

Hello, I'm trying to import virtual machines from a KVM host (centos 7.2) to an oVirt 4.0.2 Cluster using the "import" feature on GUI. If the original VM is using RAW/QCOW2 files as storage, everything works fine. But if the original VM is using a special block special device as storage (like a LVM or SAN volume), it's simply not recognized. The VM does appear in the import list of the KVM host, but it's disk count is 0! Is this a known technical obstacle or am I doing something wrong ? below is the storage part of the xml describing the original VM : <disk type='block' device='disk'> <driver name='qemu' type='raw' cache='none' io='native'/> <source dev='/dev/mapper/vg_01-lv_sys'/> <target dev='vda' bus='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/> </disk> <disk type='block' device='disk'> <driver name='qemu' type='raw' cache='none' io='native'/> <source dev='/dev/sdc'/> <target dev='vdb' bus='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/> </disk> We have hundreds of virtual machines in production with this type of configuration... How can we migrate them safely to oVirt? thanks Nelson

How to update ovirt on a single-host hosted-engine host
by Derek Atkins 29 Nov '16

29 Nov '16

Hi, I've got ovirt running on a single host (with hosted-engine). I just upgraded the engine from 4.0.4 to 4.0.5. That was pretty easy; I just put the system into global maintenance mode, then yum update, then engine-setup, then took the host out of maint mode. Easy peasy. Now, I want to update the host itself. Since it's a single host system I know I'll need to shut down all the VMs (because there's no place to migrate them). This means I'll need to shut down the engine VM, too. That would imply that I can't use the "Update" feature from the ui, right? So what IS the process to properly update a single-host host? My guess is: * shutdown all the VMs * go into global maint mode (what IS the difference between global and local?) * shutdown the engine/engine VM * yum update on the host * restart services (or reboot, I guess) * bring the system out of maintenance mode Am I missing a step? Do I need to run hosted-engine --deploy again similar to how I needed to run "engine-setup" on the engine? Or is there something else I need to run?
