Total LUN Limitations
by Ryan Chewning 14 Apr '20

14 Apr '20

I'm hoping that someone might be able to clarify a limitation found in the RedHat documentation. The documentation indicates that there is a limitation of 300 LUNS per block based storage device. Does this include LUNs which are directly mapped to a VM? Or does this referrer to LUNs which serve as a storage repository for ISOs / VM disks?

Host fails to enter in maintenance due to migration failure
by Vinícius Ferrão 13 Apr '20

13 Apr '20

Hello, I’ve a host that’s preparing to maintenance for almost 20 hours now. There’s a huge VM on it, with 32 gigs of RAM and this VM is failing migration. So, there’s a way to cancel prepare for maintenance, so the host can stop trying this migration that’s end up failing? I can just shutdown the VM to do the maintenance on the host... Thanks,

Looking through the logs I saw references to the blocksize but since that is contained in the ansible scripts which get downloaded to the host I gave up finding the source versions to try to see it I could get it going beyond that failing step. Anyway, thanks for informing me, Regards, Joop

engine certificate problems in MacOS Catalina
by Jayme 13 Apr '20

13 Apr '20

I recently setup a new ovirt environment using latest 4.3.9 installer. I can't seem to get the novnc client to work for the life of me in safari or chrome on MacOS catalina. I have downloaded the CA from the login page and imported it into keychain and made sure it was fully trusted. In both system and login keychains. Looking at this: https://support.apple.com/en-us/HT210176 seems to suggest that the certificate may be invalid if the issue date is longer than 825 days. The certificate generated by ovirt installer seems to be valid for 5 years. I'm not sure if this is the issue or something else is wrong but if cert length is a problem is there a way for me to re-regenerate a new certificate with a shorter issue period?

One more time
by eevans＠digitaldatatechs.com 13 Apr '20

I have thought about the issue with Windows vm's reporting the timezone incorrectly. I reaqlized that just last month, before I created my vm's that the Daylight Savings Time took affect moving our time up 1 hour. SO, based on that, instead of setting my time zone to US Eastern (GMT -5), I set it to SA Western (GMT -4) and the nasty exclamation mark disappeared. This tells me that DST (Daylight Savings Time) is not an option or configurable in Ovirt. I think this should be an easy fix for those of use that are stuck with it. I don't think the rest of the world participates in DST but most of the United States does. It would be nice to have those zones added as a configurable option that would switch on the dates it is nationally indicated to change. I hope the developers read this. Thanks.

DR on hyperconverged deployment
by wodel youchi 13 Apr '20

13 Apr '20

Hi, Need to understand somethings about DR on oVirt-HI - What does mean : Scheduling regular backups using geo-replication (point 3.3.4 RHHI 1.7 Doc Maintaining RHHI) : - Does this mean creating a check-point? - If yes, does this mean that the geo-replication process will sync data up to that check-point and then stops the synchronization, then repeat the same cycle the day after? does this mean that the minimum RPO is one day? - I created a snapshot of a VM on the source Manager, I synced the volume then I executed a DR, The VM was started on the Target Manager but the VM didn't have its snapshot, any idea??? Regards, be safe.

multiple subnets on hosts for vm's
by eevans＠digitaldatatechs.com 12 Apr '20

12 Apr '20

This is not critical but some functionality I think should be in Ovirt and maybe I am going about it the wrong way. I have several subnets on my physical network. My engine host is separate from the clustered hosts that house the vm's. In order for the vm's on the other subnets (vlans) to get Internet access, I have to add the extra ip addrs on the ovirtmgmt network interface. I have read and tried every solution I could find trying to add teh subnets without using the extra ip addrs option but the machine either becomes isolated or will not start at all. Can someone tell me how to add the vlans so the engine host sees and utilizes them? The engine host can get to resources on the vlans because of the router config but will not let any subnet except ovirtmgmt outside the cluster. This is not critical but something I would like to get working for future deployments. Thank you for your help. Eric

Storage domain in maintenance
by Strahil Nikolov 11 Apr '20

11 Apr '20

Hello All, I have several storage domains in maintenance mode and I can't neither detach, nor activate. Can someone explain to me what is actually doing the engine whwn I try to activate - so I can debug it? The error from vdsm-client is that the storage domain does not exist, yet it is in the DB . I assume that there is somw storage issue, but in order to debug it - I need to know what is gooing on under the hood. Thanks in advance Best Regards, Strahil Nikolov
