Story of the problems continues. Finally shut everything down, got storage domains to maintenance and then this happens: ovirtsdk4.Error: Fault reason is "Operation Failed". Fault detail is "[Physical device initialization failed. Please check that the device is empty and accessible by the host.]". HTTP response code is 400. [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Fault reason is \"Operation Failed\". Fault detail is \"[Physical device initialization failed. Please check that the device is empty and accessible by the host.]\". HTTP response code is 400."} No amount zeroing device helped. Next plan: Find out if I can restore backup to standalone server. If that fails that's the end of oVirt for me. It worked fine for a couple of years but this update hassle is too much. Should have gone until the end with 4.3.

Hmm. Is it possible that when the other node is still running v4.3 this operation can't be completed as it doesn't know how to do it.
Thanks, Juhani

It seems that it is not supported in oVirt yet? I got this response when I tried to change master with those storage domain that I have:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <fault> <detail>[Cannot switch master storage domain. Switch master storage domain operation is not supported.]</detail> <reason>Operation Failed</reason> </fault>
So is this really the only way to do this: shutdown everything and put other storage domains into maintenance? It would have been nice if this information was in the upgrade guide. It made this seem so easy and simple...

Thanks this looks like what I'm looking for. I'm still wondering how to use this. I have LUN just for new hosted storage. Ansible created storage domain to it correctly but just can't activate it. So is the idea that I activate this unattached hosted_storage domain and try to use API to make it master? I attached a screen shot how it looks currently.

To continue. I noticed that another storage domain took the data (master) now. I saw one advice that you can force change by putting the storage domain to maintenance mode. Problem is that there are VM's running on these domains. How is this supposed to work during the restore?
There is a recent change [1] by Shani (Cced) that should allow you to choose another storage domain as master. So you can create a new (temporary?) SD with the correct compatibility level and then set it to master.

Hi!
I started the upgrade from 4.3->4.4. Now I'm stuck as restoring the backup fails to create the correct storage domain for Hosted Engine. How can I create one? Error from ansible task is:
[ ERROR ] ovirtsdk4.Error: Fault reason is "Operation Failed". Fault detail is "[Domain format is different from master storage domain format]". HTTP response code is 400. [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Fault reason is \"Operation Failed\". Fault detail is \"[Domain format is different from master storage domain format]\". HTTP response code is 400."}
And from UI I can see that what has been created is a data domain. Not data (master) domain as old one was. Now I'm stuck here. This is a fibre channel system where I'm trying to do this if it is relevant.
What I could find from the logs is this: 2021-04-27 09:36:06,925+0300 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:105 storage_domain_details: {'changed': False, 'ovirt_storage_domains': [{'href': '/ovirt-engine/api/storagedomains/dd52022b-7616-47f6-9534-6f1a4084fdf4', 'comment': '', 'description': '', 'id': 'dd52022b-7616-47f6-9534-6f1a4084fdf4', 'name': 'hosted_storage', 'available': 531502202880, 'backup': False, 'block_size': 512, 'committed': 0, 'critical_space_action_blocker': 5, 'discard_after_delete': True, 'disk_profiles': [], 'disk_snapshots': [], 'disks': [], 'external_status': 'ok', 'master': False, 'permissions': [], 'status': 'unattached', 'storage': {'type': 'fcp', 'volume_group': {'id': 'HRLDCn-p7X2-5X2O-vm4h-1Wb9-wAMu-WkIwit', 'logical_units': [{'discard_max_size': 268435456, 'discard_zeroes_data': False, 'id': '36000d31005b4f6000000000000000029', 'lun_mapping': 3, 'paths': 0, 'product_id': 'Compellent Vol', 'serial': 'SCOMPELNTCompellent_Vol_0005b4f6-00000029', 'size': 536870912000, 'storage_domain_id': 'dd52022b-7616-47f6-9534-6f1a4084fdf4', 'vendor_id': 'COMPELNT', 'volume_group_id': 'HRLDCn-p7X2-5X2O-vm4h-1Wb9-wAMu-WkIwit'}]}}, 'storage_connections': [], 'storage_format': 'v5', 'supports_discard': True, 'supports_discard_zeroes_data': False, 'templates': [], 'type': 'data', 'used': 4294967296, 'vms': [], 'warning_low_space_indicator': 10, 'wipe_after_delete': False}], 'failed': False}
'master': False? I'm not sure if this creation or check. I tried this opration twice. I removed the new hosted_storage and remove also old hosted_engine domain on second try to make sure that it doesn't prevent creation of another master. No luck with that.
