Hi, All. We are attempting to migrate to a new storage domain for our oVirt 4.5.4 self-hosted engine setup, and are failing with "cannot import name 'Callable' from 'collections'" Please see below for the errors on the console.

As basic as can be install/deploy. Used ovirt-node-ng-installer-latest-el8.iso. Followed steps exactly. Took all defaults possible. After step 23 (Specify the hostname of the deployment host:) the deployment starts. It goes for quite a long time until it fails here, never getting to step 25 and asking me for storage: 2023-11-19 22:19:45,568+0000 DEBUG var changed: host "localhost" var "module_setup" type "<class 'bool'>" value: "true" 1888 2023-11-19 22:19:45,568+0000 DEBUG var changed: host "localhost" var "discovered_interpreter_python" type "<class 'ansible.utils.unsafe_proxy.AnsibleUnsafeText'>" value: ""/usr/libexec/platform-python"" 1889 2023-11-19 22:19:45,568+0000 INFO ansible ok {'status': 'OK', 'ansible_type': 'task', 'ansible_playbook': '/usr/share/ovirt-hosted-engine-setup/he_ansible/trigger_role.yml', 'ansible_host': 'localhost', 'ansible_task': 'For ce facts gathering', 'task_duration': 1} 1890 2023-11-19 22:19:45,568+0000 DEBUG ansible on_any args <ansible.executor.task_result.TaskResult object at 0x7f2028102220> kwargs 1891 2023-11-19 22:19:45,664+0000 INFO ansible task start {'status': 'OK', 'ansible_type': 'task', 'ansible_playbook': '/usr/share/ovirt-hosted-engine-setup/he_ansible/trigger_role.yml', 'ansible_task': 'ovirt.ovirt.hosted_engin e_setup : Set the name for add_host'} 1892 2023-11-19 22:19:45,664+0000 DEBUG ansible on_any args TASK: ovirt.ovirt.hosted_engine_setup : Set the name for add_host kwargs is_conditional:False 1893 2023-11-19 22:19:45,664+0000 DEBUG ansible on_any args localhost TASK: ovirt.ovirt.hosted_engine_setup : Set the name for add_host kwargs 1894 2023-11-19 22:19:45,759+0000 ERROR ansible failed { 1895 "ansible_host": "localhost", 1896 "ansible_playbook": "/usr/share/ovirt-hosted-engine-setup/he_ansible/trigger_role.yml", 1897 "ansible_result": { 1898 "_ansible_no_log": false, 1899 "msg": "The task includes an option with an undefined variable.

I've been at this for more than a week with different options/OSs. Figured this was the most basic possible configuration and yet it still doesn't work. Incredibly frustrating product.

Weirdness with attempting NFS mount
by Michaal R 17 Nov '23

17 Nov '23

I'm attempting to mount a share from a TrueNAS server in oVirt through the Storage > Storage Domains UI as a New Domain. Whenever I try to add the domain (as server:share), it kicks back a Permission Denied error. Looking at the vdsm.log file, I see the below snippet: 2023-11-17 10:05:32,059-0600 INFO (jsonrpc/7) [vdsm.api] START connectStorageServer(domType=1, spUUID='00000000-0000-0000-0000-000000000000', conList=[{'password': '********', 'protocol_version': 'auto', 'port': '', 'iqn': '', 'connection': '192.168.1.11:/mnt/POOL0', 'ipv6_enabled': 'false', 'id': '00000000-0000-0000-0000-000000000000', 'user': '', 'tpgt': '1'}]) from=::ffff:192.168.1.16,50468, flow_id=31d18c09-2e12-480f-8d6d-722a9fe78029, task_id=05818e9d-562f-4ca7-a19b-5c3b5a02bae8 (api:31) 2023-11-17 10:05:32,060-0600 INFO (jsonrpc/7) [storage.storageServer] Creating directory '/rhev/data-center/mnt/192.168.1.11:_mnt_POOL0' (storageServer:217) 2023-11-17 10:05:32,060-0600 INFO (jsonrpc/7) [storage.fileutils] Creating directory: /rhev/data-center/mnt/192.168.1.11:_mnt_POOL0 mode: None (fileUtils:213) 2023-11-17 10:05:32,060-0600 INFO (jsonrpc/7) [storage.mount] mounting 192.168.1.11:/mnt/POOL0 at /rhev/data-center/mnt/192.168.1.11:_mnt_POOL0 (mount:190) 2023-11-17 10:05:32,150-0600 WARN (jsonrpc/7) [storage.oop] Permission denied for directory: /rhev/data-center/mnt/192.168.1.11:_mnt_POOL0 with permissions:7 (outOfProcess:176) 2023-11-17 10:05:32,150-0600 INFO (jsonrpc/7) [storage.mount] unmounting /rhev/data-center/mnt/192.168.1.11:_mnt_POOL0 (mount:198) 2023-11-17 10:05:32,200-0600 ERROR (jsonrpc/7) [storage.storageServer] Could not connect to storage server (storageServer:75) Traceback (most recent call last): File "/usr/lib/python3.9/site-packages/vdsm/storage/fileSD.py", line 64, in validateDirAccess getProcPool().fileUtils.validateAccess(dirPath) File "/usr/lib/python3.9/site-packages/vdsm/storage/outOfProcess.py", line 178, in validateAccess raise OSError(errno.EACCES, os.strerror(errno.EACCES)) PermissionError: [Errno 13] Permission denied During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/lib/python3.9/site-packages/vdsm/storage/storageServer.py", line 73, in connect_all con.connect() File "/usr/lib/python3.9/site-packages/vdsm/storage/storageServer.py", line 507, in connect return self._mountCon.connect() File "/usr/lib/python3.9/site-packages/vdsm/storage/storageServer.py", line 241, in connect six.reraise(t, v, tb) File "/usr/lib/python3.9/site-packages/six.py", line 709, in reraise raise value File "/usr/lib/python3.9/site-packages/vdsm/storage/storageServer.py", line 233, in connect fileSD.validateDirAccess( File "/usr/lib/python3.9/site-packages/vdsm/storage/fileSD.py", line 75, in validateDirAccess raise se.StorageServerAccessPermissionError(dirPath) vdsm.storage.exception.StorageServerAccessPermissionError: Permission settings on the specified path do not allow access to the storage.

It previously was able to mount an NFS share from the host to itself when I initially setup the server for testing. When I do an ls -l on the directory it's trying to create the mount point in, I see ownership looks correct.

Something that got misconfigured, maybe? Or something I can configure to fix this?

oVirt host locked in installing status
by Michele la Torre 16 Nov '23

16 Nov '23

Hi all, I have an oVirt installation (version 4.5.4-1.el8) with the engine installed in standalone mode. One of the hosts, after encountering some issues with the certificate renewal (which have now been resolved, and there are no current errors related to this), is stuck in the "Installing" state. I've checked the logs, but there are no errors reported. Do you have any ideas on what I can try to resolve this? Best regards, Michele

obtain direct LUN wwid in the guest
by LS CHENG 14 Nov '23

14 Nov '23

Hi all I am working with Oracle Linux Virtualization Manager 4 (OLVM) which is based on ovirt. When I worked with OLVM 3 and when assigning direct lun to the guests in the guest I could obtain LUN's wwid with this command /usr/lib/udev/scsi_id -g -u -d /dev/sdc1 36000c29f1382ae964d67392dfdfaaf0f similar to VMWare's disk.EnableUUID But now in OLVM 4 I am getting this in the guest which is not LUN's wwid /usr/lib/udev/scsi_id -g -u -d /dev/sdc 0QEMU_QEMU_HARDDISK_671b475e-98ab-4f3b-a23d-2f8eed964e92 I wonder if is it possible to get LUN's wwid in the guest in OLVM 4? Thanks1

Hi I'm trying to replace the old certificate of the engine, so tha I can again access the management console. I've been reading thorugh a lot of articels and threads and the easiest solution, should be by running the engine-setup. I always get the following error: [ INFO ] Creating CA: /etc/pki/ovirt-engine/ca.pem [ ERROR ] Failed to execute stage 'Misc configuration': Command '/usr/share/ovirt-engine/bin/pki-enroll-pkcs12.sh' failed to execute How can I fix this? Thanks in advance for any help! Kind regards, Dominic

Gluster: Ideas for migration
by jonas＠rabe.ch 10 Nov '23

10 Nov '23

Hello I have to migrate the Gluster volumes from an old oVirt cluster to a newly built one. I looked into migration strategies, but everything that Red Hat recommends is related to replacing old bricks. In a testing environment I created two clusters and wanted to migrate one volume after the other. Unfortunately that fails because a node cannot be part of two clusters at the same time. The next thing I see, is to recreate the volumes on the new cluster, then constantly rsync the files from the old cluster to the new one and at a specified point in time make the cut over where I stop the applicaiton, do a final rsync and remount the new volume under the old path. Is there any other, nicer way I could accomplish migrating a volume from one Gluster cluster to another?
