Re: External ceph storage

No, The only way you have is to configure cinder to manage ceph pool or in alternative you have to deploy an iscsi gateway, no other ways are available at the moment. So you can't use rbd directly.

oVirt node 4.2.x - custom multipath.conf and external storage availability
by Roberto Nunin 13 Aug '18

13 Aug '18

HI all How can I provide to my oVirt hosts a custom multipath.conf, considering that we are using shared/mirrored FC storage from HPE 3PAR with high availability of provided LUNs, using peer-persistance feature ? To configure correctly this require a custom multipath.conf is required. How I can avoid it will be overwritten during upgrades ? Second topic: Is ALUA feature supported also in oVirt nodes, like for standard RHEL 6/7 and/or CentOS 6/7 ? I was digging for a while into user's digest, but not able to find focused informations. This is the feature needed by peer-persistance, allowing two different volumes to be masked toward a given host with the same WWN and LUN number. Thanks in advance -- Roberto

Drive letter / scsi id not consistent
by Nathan March 09 Aug '18

09 Aug '18

Hi, Managing disks in the ovirt gui seems completely error prone since the GUI ordering does not seem to be used in any practical way. The scsi ID's are not exposed via the GUI either, so if you have 2 drives of the same size on NFS there's no way to identify which is which without resorting to dumping the xml. I see in the xml that the target dev is correct and matches up with the GUI's drive order, but the scsi unit seems to be generated based on the order of last activated: <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/> <source file='/rhev/data-center/mnt/10.1.32.10:_sas01/2060a19f-f26c-4dba-a559-83541a4d0c7a/images/b622cde9-ffc4-487b-8038-f7cb7fbc00a1/7240b4b2-5ab1-40ab-99bb-09c69fd835f6'/> <backingStore/> <target dev='sda' bus='scsi'/> <serial>b622cde9-ffc4-487b-8038-f7cb7fbc00a1</serial> <boot order='1'/> <alias name='ua-b622cde9-ffc4-487b-8038-f7cb7fbc00a1'/> <address type='drive' controller='0' bus='0' target='0' unit='1'/> </disk> <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/> <source file='/rhev/data-center/mnt/10.1.32.10:_sas01/2060a19f-f26c-4dba-a559-83541a4d0c7a/images/86765f60-4240-44f4-b437-f22b2cc3df1a/482a363e-461a-4f37-876c-43ceb529a93a'/> <backingStore/> <target dev='sdb' bus='scsi'/> <serial>86765f60-4240-44f4-b437-f22b2cc3df1a</serial> <alias name='ua-86765f60-4240-44f4-b437-f22b2cc3df1a'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/> <source file='/rhev/data-center/mnt/10.1.32.10:_sas01/2060a19f-f26c-4dba-a559-83541a4d0c7a/images/0b020d24-3dea-4be7-931a-9c25ccfeec48/7e3957ff-a3bf-4080-a7b6-ddad7f63a299'/> <backingStore/> <target dev='sdc' bus='scsi'/> <serial>0b020d24-3dea-4be7-931a-9c25ccfeec48</serial> <alias name='scsi0-0-0-3'/> <address type='drive' controller='0' bus='0' target='0' unit='3'/> </disk> After deactivating the other 2 disks and rebooting the machine, sda has now become unit 3: <target dev='sda' bus='scsi'/> <serial>b622cde9-ffc4-487b-8038-f7cb7fbc00a1</serial> <boot order='1'/> <alias name='ua-b622cde9-ffc4-487b-8038-f7cb7fbc00a1'/> <address type='drive' controller='0' bus='0' target='0' unit='3'/> and then I shutdown, activated the extra 2 drives, booted it back up but now I'm still on unit 3: <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/> <source file='/rhev/data-center/mnt/10.1.32.10:_sas01/2060a19f-f26c-4dba-a559-83541a4d0c7a/images/b622cde9-ffc4-487b-8038-f7cb7fbc00a1/7240b4b2-5ab1-40ab-99bb-09c69fd835f6'/> <backingStore/> <target dev='sda' bus='scsi'/> <serial>b622cde9-ffc4-487b-8038-f7cb7fbc00a1</serial> <boot order='1'/> <alias name='ua-b622cde9-ffc4-487b-8038-f7cb7fbc00a1'/> <address type='drive' controller='0' bus='0' target='0' unit='3'/> </disk> <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/> <source file='/rhev/data-center/mnt/10.1.32.10:_sas01/2060a19f-f26c-4dba-a559-83541a4d0c7a/images/86765f60-4240-44f4-b437-f22b2cc3df1a/482a363e-461a-4f37-876c-43ceb529a93a'/> <backingStore/> <target dev='sdb' bus='scsi'/> <serial>86765f60-4240-44f4-b437-f22b2cc3df1a</serial> <alias name='ua-86765f60-4240-44f4-b437-f22b2cc3df1a'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/> <source file='/rhev/data-center/mnt/10.1.32.10:_sas01/2060a19f-f26c-4dba-a559-83541a4d0c7a/images/0b020d24-3dea-4be7-931a-9c25ccfeec48/7e3957ff-a3bf-4080-a7b6-ddad7f63a299'/> <backingStore/> <target dev='sdc' bus='scsi'/> <serial>0b020d24-3dea-4be7-931a-9c25ccfeec48</serial> <alias name='ua-0b020d24-3dea-4be7-931a-9c25ccfeec48'/> <address type='drive' controller='0' bus='0' target='0' unit='1'/> </disk> I managed to get things into the correct state by shutting down the VM, deactivating all the disks, then activating them in the order I want them to show up. This sets the correct order of unit 0 for sda, unit 1 for sdb, unit 2 for sdc. Is there some way to make ovirt treat this in a sane way and always expose the scsi devices in the same order as the GUI (and the "target dev" field)? Cheers! Nathan

better understand ovirt-engine functions
by stuartk＠alleninstitute.org 07 Aug '18

07 Aug '18

I've been reading through documentation https://www.ovirt.org/documentation/architecture/architecture/ https://www.ovirt.org/documentation/self-hosted/Self-Hosted_Engine_Guide/ But am struggling still to understand the role ovirt-engine plays. Would anyone have recommends for additional reads? The problem I'm tackling currently looks like this: - We have (2) oVirt Data Centers, each populated by a single Cluster. The Data Centers are physically & network-wise 'distant' from one another - hosted-engine runs on (3) of the (4) Hosts in Data Center A / Cluster A. hosted-engine does not run on Data Center B / Cluster B - When we disrupt network connectivity around Cluster A (yes, that's Cluster *A*), Hosts in Cluster B crash (requiring a power cycle) and Guests in Cluster B get stopped and paused I'm struggling to understand why mussing with Cluster A affects Cluster B. From pcaps, I can see plenty of TLS traffic from Cluster A's Hosts -- presumably from ovirt-engine running on Cluster A -- exchanged with Cluster B. So, during my last maintenance window, I put hosted-engine into maintenance mode ... but Hosts/VMs in Cluster B were still affected. Where do I go to better understand what ovirt-engine does when it is 'managing' Hosts & VMs? --sk

MoM - Not working ? How to use it ?
by jeanbaptiste＠nfrance.com 07 Aug '18

Hello, I'm trying to test Memory balloon useful functionality, but l'm unable to make it work successfuly. Firstly, I enable the MOM on my Cluster: Memory Balloon Enable Memory Balloon Optimization Secondly, I configure a VM virtual machine like this: On system tab: Memory Size : 28672 MB Maximum memory : 28672 MB On Ressource allocation tab: Memory Allocation: Physical Memory Guaranteed : 2048 MB Memory Balloon Device: Enabled Thirdly, I test 1- I boot the VM. After boot VM consume 200MB 2- I lauch perl program which consume 26GB. 3- During this, Host RAM usage is near 90% 4- I stop the perl program, and on guest side, RAM usage drop down to 200Mo 5- On host side, RAM usage keep to 24 - 26GB. I wait some time to show if the qemu-vm process drop is host-ram-usage. Ram usage keep to 24GB. 6- I try to launch another VM like the first one (but with 8GB RAM and 2GB Guaranteed) , on the host (to "force" Mom ?) but I'm unable to lauch it, Host free mem is insufficient I change MoM log to debug to show something: 2018-07-31 11:49:31,887 - mom.RPCServer - INFO - ping() 2018-07-31 11:49:31,888 - mom.RPCServer - INFO - getStatistics() 2018-07-31 11:49:31,888 - mom.Monitor - DEBUG - Field 'mem_free' not known.

Unable to revive host after a reboot
by Julius Schwartzenberg 03 Aug '18

03 Aug '18

Hi, I recently had to shutdown my oVirt system which contains both the engine and the host. After it came back up, the host was not able to initialize anymore from the oVirt UI. First it kept getting stuck in a loop with setting "ExecutingStarted: Jul 30, 2018, 9:06:21 AMSetting Host pc331 to Non-Operational mode." This was being repeated over and over again. It also gave this error: Host pc331 does not comply with the cluster Default networks, the following networks are missing on host: 'ovirtmgmt' Even though I am using that interface (ovirtmgmt) to access the system and 'ip addr show' shows that it's set up properly. I tried some more things, including upgrading the host, When I do that, the status changes to 'Installing' and later to 'Install Failed'. Here are the engine.log, vdsm.log and ovirt-host-deploy*.log: https://drive.google.com/open?id=13vIUDVjPynmAK0pnFRLabDfUlG1lmkpI https://drive.google.com/open?id=10Zm2dDpxM2k5A2bEs_l6gOv_yWv4cjlN https://drive.google.com/open?id=1AieWMzRuA0gZj3x5yDH1AGnsT2E3VtOM Any idea what is going wrong (what I'm doing wrong) and how to solve it? Thanks in advance! Best regards, Julius
