Problem with connecting the Storage Domain (Host host2 cannot access the Storage Domain(s) <UNKNOWN>)
by Patrick Lomakin 05 Apr '20

05 Apr '20

Hello, everyone! I need specialist help, because I'm already desperate. My company has four hosts that are connected to the vault. Each host has its own IP to access the storage, which means host 1 has an ip 10.42.0.10 and 10.42.1.10 -> host 2 has an ip 10.42.0.20 and 10.42.0.20 respectively. Host 1 cannot ping the address 10.42.0.20. Hardware I tried to explain in more detail. Host 1 has ovirt node 4.3.9 installed and hosted-engine deployed. When trying to add host 2 to a cluster it is installed, but not activated. There is an error in ovirt manager - "Host host2 cannot access the Storage Domain(s) <UNKNOWN>" and host 2 goes to "Not operational" status. On host 2, it writes "connect to 10.42.1.10:3260 failed (No route to host)" in the logs and repeats indefinitely. I manually connected host 2 to the storage using iscsiadm to ip 10.42.0.20. But the error is not missing(. At the same time, when the host tries to activate it, I can run virtual machines on it until the host shows an error message. VMs that have been run on host 2 continue to run even when the host has "Not operational" status. I assume that when adding host 2 to a cluster, ovirt tries to connect it to the same repository host 1 is connected to from ip 10.42.1.10. There may be a way to get ovirt to connect to another ip address instead of the ip domain address for the first host. I'm attaching logs: ----> /var/log/ovirt-engine/engine.log 2020-03-31 09:13:03,866+03 WARN [org.ovirt.engine.core.dal.dbbroker.auditloghan dling.AuditLogDirector] (EE-ManagedThreadFactory-engineScheduled-Thread-90) [7fa128f4] EVENT_ID: VDS_SET_NONOPERATIONAL_DOMAIN(522), Host host2.school34.local c annot access the Storage Domain(s) <UNKNOWN> attached to the Data Center DataCenter.

Failing to redeploy self hosted engine

I keep running into this error when I try to (re)deploy self-hosted engine. # ovirt-hosted-engine-cleanup # hosted-engine --deploy ... ... [ INFO ] TASK [ovirt.hosted_engine_setup : Fail with error description] [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "The host has been set in non_operational status, deployment errors: code 9000: Failed to verify Power Management configuration for Host physhost01.example.com, fix accordingly and re-deploy."} I shut down all of the VM's and detached the storage before cleaning up and trying to re-deploy the hosted engine, first time I've run into this particular problem. Any help appreciated Brett

NFS permissions error on ISODomain file with correct permissions
by Shareef Jalloq 03 Apr '20

03 Apr '20

Hi, I asked this question in another thread but it seems to have been lost in the noise so I'm reposting with a more descriptive subject. I'm trying to start a Windows VM and use the virtio-win VFD floppy to get the drivers but the VM startup fails due to a permissions issue detailed below. The permissions look fine to me so why can't the VFD be read? Shareef. I found a permissions issue in the engine.log: 2020-03-25 21:28:41,662Z ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (ForkJoinPool-1-worker-14) [] EVENT_ID: VM_DOWN_ERROR(119), VM win-2019 is down with error.

Ok. Personally, I like having an ISO repository, but I like the fact that's it will be optional. Thanks.

I found that out as I was testing oVirt and had not created a separate ISO Domain. I believe it was Strahil who pointed me in the right direction. So if one does not have an ISO Domain, it is no longer required. Along with the fact that ISO Domains are or in the process of being deprecated. ________________________________________ From: eevans(a)digitaldatatechs.com <eevans(a)digitaldatatechs.com> Sent: Wednesday, March 25, 2020 3:13 PM To: Robert Webb; 'Shareef Jalloq'; users(a)ovirt.org Subject: RE: [ovirt-users] Re: Windows VirtIO drivers That may be true, but in the ISO domain, when you open virt viewer you can change the cd very easily...maybe it works that way as well..

You can upload to a Data Domain and when you highlight the VM in the management GUI, select the three dots in the top left for extra options and there is a change cd option. That option will allow for attaching an ISO from a Data Domain. That is what I recall when I was using oVirt a month or so ago. ________________________________________ From: eevans(a)digitaldatatechs.com <eevans(a)digitaldatatechs.com> Sent: Wednesday, March 25, 2020 2:28 PM To: 'Shareef Jalloq'; users(a)ovirt.org Subject: [ovirt-users] Re: Windows VirtIO drivers You have to copy the iso and vfd files to the ISO domain to make them available to the vm's that need drivers. engine-iso-uploader options list # engine-iso-uploader options upload file file file Documentation is found here: https://www.ovirt.org/documentation/admin-guide/chap-Utilities.html Eric Evans Digital Data Services LLC. 304.660.9080 [cid:image001.jpg@01D602B1.9FEA2EC0] From: Shareef Jalloq <shareef(a)jalloq.co.uk> Sent: Wednesday, March 25, 2020 1:51 PM To: users(a)ovirt.org Subject: [ovirt-users] Windows VirtIO drivers Hi, it seems the online documentation regarding the windows installation steps is well out of date.
