[ovirt-users] Re: Should I migrate existing oVirt Engine, or deploy new?
I thought I'd report back to the list and mention that I was successful in migrating off of the hyperconverged environment onto a stand-alone engine environment, and Gluster has been removed from the oVirt configuration. I ran into a few minor hiccups, all of which were resolved fairly easily, and I took notes. I intend to submit a PR to the github documentation, since none currently exist for migrating the engine off of a hyperconverged environment. My only remaining questions at this point is: - Are there things on the hosts themselves that I should cleanup? I noticed that the "hosted-engine" command still exists. I went to run a `yum remove` on that, and it tried to remove basically everything... so I figured that wasn't actually a good idea. - Do I need to do anything in the oVirt config (maybe something in the Postgres database) to basically tell it that it is no longer self-hosted, but is instead stand-alone?

[ovirt-users] Re: VMs hang periodically: gluster problem?
Parameter cluster.choose-local set to off. I confirm the filesystem of the bricks are all XFS as required. I started the farm only to accomplish a test bench of oVirt implementation, so I used 3 hosts based on ryzen5 processor desktop environment equipped with 4 DDR (4 32GB modules) and 1 disk for the OS and the others to use as data brick or nfs target. All SATA based, while the OS is installed on an internal M.2 disk. The node4 as it doesn't require much space as it is the arbiter, uses only the internal M.2 disk. Every host is equipped with dual channel x520 intel chipset with 2 SFP+ configured with 9000 packet size. Access lan is the management lan (and even the lan used by gluster) the VLAN are the "production" vlans. node2: /dev/mapper/glustervg-glhe on /brickhe type xfs (rw,relatime,seclabel,attr2,inode64,logbufs=8,logbsize=32k,noquota) /dev/mapper/glustervg-gv0 on /brickgv0 type xfs (rw,relatime,seclabel,attr2,inode64,logbufs=8,logbsize=32k,noquota) /dev/mapper/glustervg-gv1 on /brickgv1 type xfs (rw,relatime,seclabel,attr2,inode64,logbufs=8,logbsize=32k,noquota) Devices file mpath_uuid part4-mpath-Samsung_SSD_860_EVO_500GB_S4XBNF0N334942Y PVID 9iyl5761LWcy3AYy36fNcPk0fADjNYtC last seen on /dev/mapper/Samsung_SSD_860_EVO_500GB_S4XBNF0N334942Y4 not found.

[ovirt-users] Re: Error during deployment of ovirt-engine
I meant what exactly is broken and if there is a workaround or a planned fix.
I performed a deployment using hosted-engine. This goes on step further, but
fails while waiting for the host:
[...]
[ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Obtain SSO token using
username/password credentials]
[ INFO ] ok: [localhost]
[ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Wait for the host to be up]
[ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Notify the user about a
failure]
[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Host is not
up, please check logs, perhaps also o
n the engine machine"}
[...]
On the hosted-engine, I see in
/var/log/ovirt-engine/host-deploy/ovirt-host-deploy-ansible-20220917140938-server-005.admin.int.rabe.ch-937b3c69-a4d5-45c7-af0f-b8705490ff2a.log:

But netaddr is installed:
[root@ovirt-engine-test host-deploy]# pip3 install netaddr
WARNING: Running pip install with root privileges is generally not a good idea.
Try `pip3 install --user` instead.
Requirement already satisfied: netaddr in /usr/lib/python3.6/site-packages
Any ideas what I can do?

[ovirt-users] Migrating VM from old ovirt to a new one
Hi everyone I would like to ask you a question I have an ovirt 4.4 which got corrupted certs and I can't access the gui. It gives me error 500 internal when I want to access. I have a new ovirt 4.5 on glusterfs which I would like to migrate all my vm's to. Is this possible? Can it be done by cli? It would save me from having to reinstall all the vm's. ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/556KSQG5K6CYDTWJGU5NET3UO34YYFXM/
