How to handle broken NFS storage?
by David White 06 Jun '21

06 Jun '21

I'm trying to figure out how to keep a "broken" NFS mount point from causing the entire HCI cluster to crash. HCI is working beautifully. Last night, I finished adding some NFS storage to the cluster - this is storage that I don't necessarily need to be HA, and I was hoping to store some backups and less-important VMs on, since my Gluster (sssd) storage availability is pretty limited. But as a test, after I got everything setup, I stopped the nfs-server. This caused the entire cluster to go down, and several VMs - that are not stored on the NFS storage - went belly up. Once I started the NFS server process again, HCI did what it was supposed to do, and was able to automatically recover. My concern is that NFS is a single point of failure, and if VMs that don't even rely on that storage are affected if the NFS storage goes away, then I don't want anything to do with it. On the other hand, I'm still struggling to come up with a good way to run on-site backups and snapshots without using up more gluster space on my (more expensive) sssd storage. Is there any way to setup NFS storage for a Backup Domain - as well as a Data domain (for lesser important VMs) - such that, if the NFS server crashed, all of my non-NFS stuff would be unaffected?

Hosted-engine fail and host reboot
by Dominique D 05 Jun '21

I tried with a 1 baremetal host, 3 baremetals or virtual hosts and I still have the same problem for installing the hosted-engine. Hyperconverge installs well. I have tried with multiple version of ovirt ISO file 4.4.1 and 4.4.4 and 4.4.6. when I run hosted-engine --deploy or with the cockpit, it creates a temporary VM in the 192.168.222.x subnet and I am able to connect in ssh on this temporary ip. When the script displays "TASK [ovirt.ovirt.hoted_engine_setup]: Wait for the host to be up" the server reboots and I have nothing left. problem when creation of the ovirtmgmt? here all my log https://drive.google.com/drive/folders/1kFFSlIqbjVwSN8t88aQZZR45DYEHPUvt?us… 021-05-26 10:15:09,135-0400 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:111 TASK [ovirt.ovirt.hosted_engine_setup : Always revoke the SSO token] 2021-05-26 10:15:10,439-0400 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:105 {'msg': "You must specify either 'url' or 'hostname'.", 'invocation': {'module_args': {'state': 'absent', 'ovirt_auth': {'changed': False, 'ansible_facts': {'ovirt_auth': {'token': 'Mz2onwB7qWX2x8HnJVgetQIQ9U4eVziRt8TEabfoizI2B98d0PDp-yxTU92a9lbun2vcr_i5yOXRsJKJKhqkVw', 'url': 'https://oe.telecom.lan/ovirt-engine/api', 'ca_file': None, 'insecure': True, 'timeout': 0, 'compress': True, 'kerberos': False, 'headers': None}}, 'failed': False, 'attempts': 1}, 'timeout': 0, 'compress': True, 'kerberos': False, 'url': None, 'hostname': None, 'username': None, 'password': None, 'ca_file': None, 'insecure': None, 'headers': None, 'token': None}}, '_ansible_no_log': False, 'changed': False} 2021-05-26 10:15:10,540-0400 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:105 ignored: [localhost]: FAILED! => {"changed": false, "msg": "You must specify either 'url' or 'hostname'."} 2021-05-26 10:15:11,643-0400 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:111 TASK [ovirt.ovirt.hosted_engine_setup : include_tasks] 2021-05-26 10:15:12,647-0400 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:111 ok: [localhost] 2021-05-26 10:15:13,851-0400 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:111 TASK [ovirt.ovirt.hosted_engine_setup : Obtain SSO token using username/password credentials] 2021-05-26 10:15:15,261-0400 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:111 ok: [localhost] 2021-05-26 10:15:17,275-0400 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:111 TASK [ovirt.ovirt.hosted_engine_setup : Wait for the host to be up] 2021-05-26 10:22:54,758-0400 ERROR otopi.context context._executeMethod:154 Failed to execute stage 'Closing up': SIG1 2021-05-26 10:22:54,762-0400 DEBUG otopi.context context.dumpEnvironment:765 ENVIRONMENT DUMP - BEGIN 2021-05-26 10:22:54,763-0400 DEBUG otopi.context context.dumpEnvironment:775 ENV BASE/error=bool:'True' 2021-05-26 10:22:54,763-0400 DEBUG otopi.context context.dumpEnvironment:775 ENV BASE/exceptionInfo=list:'[(<class 'RuntimeError'>, RuntimeError('SIG1',), <traceback object at 0x7fa8fc1ca1c8>)]' thank you

Adding a Ubuntu Host's NFS share to oVirt
by David White 04 Jun '21

04 Jun '21

Hello, Is it possible to use Ubuntu to share an NFS export with oVirt?I'm trying to setup a Backup Domain for my environment. I got to the point of actually adding the new Storage Domain. When I click OK, I see the storage domain appear momentarily before disappearing, at which point I get a message about oVirt not being able to obtain a lock. It appears I'm running into the issue described in this thread: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/BNVXUH5B26FBFC… ... Although the actual export is ext4, not xfs. From what I'm reading on that thread and elsewhere, it sounds like this problem is a result of SELinux not being present, is that correct? Is my only option here to install an OS that supports SELinux? Sent with ProtonMail Secure Email.

I think you can download and install the ovirt-engine-appliance rpm (the big one) from https://resources.ovirt.org/pub/ovirt-4.4/rpm/el8/x86_64/ in advance.

Can't remove snapshot
by David Johnson 04 Jun '21

04 Jun '21

Hi all, I patched one of my Windows VM's yesterday. I started by snapshotting the VM, then applied the Windows update. Now that the patch has been tested, I want to remove the snapshot. I get this message: Error while executing action: win-sql-2019: - Cannot remove Snapshot. The following attached disks are in ILLEGAL status: win-2019-tmpl_Disk1 - please remove them and try again. Does anyone have any thoughts how to recover from this? I really don't want to keep this snapshot hanging around. Thanks in advance, *David Johnson*
