Re: Hosted Engine can't migrate

Hi Bradley, usually this is not supposed to happen. I can propose you a fast fix: - Set a node into maintenance (via the UI) and then from the "Installation" drop down menu (upper right) click "reinstall" There is a tab for the HostedEngine and you have to mark it as deployed/installed If it doesn't work,ssh to one of the hosts and provide the output of: hosted-engine --vm-status Best Regards В сряда, 18 ноември 2020 г., 08:08:36 Гринуич+2, McNamara, Bradley <bradley.mcnamara(a)seattle.gov> написа: I'm new to oVirt, but not new to virtualization technologies. I've run into a wall, but the solution has gotta be simple. I've seen other threads with the same issue, but a solution is never posted. I've followed the guide perfectly.

Thanks. :-) > If you go in Compute --> Hosts in web admin gui, do the added hosts have a crown icon on the left of their "Name" column? If not, when you added them possibly you overlooked the "Hosted Engine" section in the window, where by default, if I'm not wrong, the value is "None": that means that the added host doesn't contributed to be one of the "Hosted Engine" ones electable to host the engine VM, but only an hyoervisor. Long time ago I opened two bugzillas about this default with some notes for improving a better experience.... If this is the case, you can remove the hosts one by one and add them again selecting "Deploy" in the Hosted Engine section, for how many you would like to contribute to the score and to be able to host the hosted engine VM. HIH, Gianluca

Please check/share /var/log/ovirt-hosted-engine-ha/* on all hosts, as well as output of 'hosted-engine --vm-status' on all of them. Good luck and best regards, -- Didi

ovirt-shell SSL Error
by FRIES, Dirk, SHS Informatik 17 Nov '20

17 Nov '20

Hello there, I am trying to connect via ovirt-shell to my ovirt manager. To do this I've downloaded the CA File (https://127.0.0.1/ovirt-engine/services/pki-resource?resource=ca-certificat…) to /tmp and set up my config in .ovirtshellrc : [cli] autoconnect = True autopage = True [ovirt-shell] username = adminuser renew_session = False timeout = None extended_prompt = False url = https://127.0.0.1/api insecure = False kerberos = False filter = False session_timeout = None ca_file = /tmp/pki-resource?resource=ca-certificate dont_validate_cert_chain = True key_file = None password = somepassword cert_file = None So when I am trying to connect I get the following error: (60, "Peer's certificate issuer has been marked as not trusted by the user.") While researching I also found a pretty similar issue here https://lists.ovirt.org/archives/list/users@ovirt.org/thread/IYG6AQPII25366… but unfortunally there is no solution posted. Does anyone have a hint for me what could cause this problem or where to look else ? Thanks a lot ! Bye, Dirk

In my opinion the slowness could be caused for not using SSD disks and because of a low polling interval by the DWHd, but that's just my assumption and I've been unable to get some data that would confirm this.

Hi, I have also sometimes the issue with snapshots or disk move, which is also related to snapshots, when the engine process is running for a longer time. After restarting the engine service, then it is working again for several weeks, until it gets too long and issues starting again to happen. I had never the time to dig in deeper here and I'm never on a version, which is still supported, but it would be nice to here, if you maybe have the same issue? How long was your engine process running, until the issues have started?

This have been an issue for quite some time, all since beginning of 4.3 we get "vm with illegal snapshots" almost every week, and most often we can remove the snapshot and all is ok, but now this have escalated quite much and leaves us with customer VM that we may not be able to reboot or that the disk gets corrupted, that have happed a few times. This is the VM with most snapshots that we are unable to remove any of them. Engine is on 4.3.10 and hosts on 4.3.9 How can i safely remove these snapshots? (I am not super comfortable around database "hacking" so some informative description would be much appreciated.) And how can we eliminate that these things happen?

VM with illegal snapshots

Hi, due to a bug in our Ovirt integrated backup system now we have some VMs with snapshots in illegal state. It seems that there's an inconsistency between the db and the real status of images on disk. Let me show an example: engine=# select image_guid,parentid,imagestatus,vm_snapshot_id,volume_type,volume_format,active from images where image_group_id='e34f77cb-54d5-40d0-b539-e0a5fd512d2d'; image_guid | parentid | imagestatus | vm_snapshot_id | volume_type | volume_format | active --------------------------------------+--------------------------------------+-------------+--------------------------------------+-------------+---------------+-------- a107b6c4-842e-4b40-9215-c965431a0c0f | 00000000-0000-0000-0000-000000000000 | 4 | d19d6ca3-1989-4c67-8ee7-c0c43b3e6d74 | 2 | 4 | f a4c86a68-9123-454c-b417-1b15038a4bf2 | a107b6c4-842e-4b40-9215-c965431a0c0f | 1 | e7a405ee-8fd4-4733-ae9c-5252bf07c9d3 | 2 | 4 | f f6a61f2e-26bd-4b63-97c6-d66913ce48c5 | a4c86a68-9123-454c-b417-1b15038a4bf2 | 1 | 9d0958b9-4995-4e11-a027-a32d4bac52e4 | 2 | 4 | t (3 rows) [root@host02 ~]# lvs -o+lv_tags |grep e34f77cb-54d5-40d0-b539-e0a5fd512d2d a107b6c4-842e-4b40-9215-c965431a0c0f 459011cf-ebb6-46ff-831d-8ccfafd82c8a -wi------- 149.50g IU_e34f77cb-54d5-40d0-b539-e0a5fd512d2d,MD_68,PU_00000000-0000-0000-0000-000000000000 f6a61f2e-26bd-4b63-97c6-d66913ce48c5 459011cf-ebb6-46ff-831d-8ccfafd82c8a -wi------- 10.00g IU_e34f77cb-54d5-40d0-b539-e0a5fd512d2d,MD_348,PU_a107b6c4-842e-4b40-9215-c965431a0c0f so image guid a4c86a68-9123-454c-b417-1b15038a4bf2 is not present on disk, i think that the image was correctly merged but not removed from the database.
