Re: [ovirt-users] Hosted engine setup question
Dear Charles, Thank you for your reply. I don't want to make an another storage domain, I just want to do a detach-attach procedure with the existing. Also, I have an another question. Is it possible delete snapshots in 4.1 what were created in 3.5? How is safe this? I have some vm snapshot in the old system, but I don't want more outage with deleting them.The 3.5 does not support the live snapshot deleting, but the 4.1 yes.

Re: [ovirt-users] Hosted engine setup question
I did a 3.6 to 4.1 like this. I moved all of my VMs to a new storage domain (the other was hyperconverged gluster) and then took a full outage, shut down all of my VMs, detached from 3.6, and imported on 4.1. I had no issues other than expected mac address changes, but I think you can manually override this in the engine somewhere If you are worried, do it with one VM. Create a new storage domain that both clusters can "see", move one VM to the domain on 3.6, detach, and import to 3.1. Bring the VM up If it is Linux VM's older than systemd and using sysvinit, you will hit issues where your MAC address will change and udev will move it to eth# wherever # is the next available NIC in your VM host On Mon, Oct 2, 2017 at 12:54 PM, Demeter Tibor wrote: > Hi, > Can anyone answer my questions? > > Thanks in advance, > R, > > Tibor > > - 2017. szept.. 19., 8:31, Demeter Tibor írta: > > > - I have a productive ovirt cluster based on 3.5 series.

[ovirt-users] Hosted engine setup question
Hi, I just installed a hosted engine based four nodes cluster to glustered storage. It seems to working fine, but I have some question about it. - I would like to make an own cluster and datacenter. Is it possible to remove a host and re-add to an another cluster while it is running the hosted engine? - Is it possible to remove default datacenter without any problems? - I have a productive ovirt cluter that is based on 3.5 series. It is using a shared nfs storage. Is it possible to migrate VMs from 3.5 to 4.1 with detach shared storage from the old cluster and attach it to the new cluster? - If yes what will happend with the VM properies? For example mac addresses, limits, etc. Those will be migrated or not? Thanks in advance, Regard Tibor ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
