Hi all,
I'm using oVirt SDK python for retrieving info about storage domain, in several
hosts (centos7/ovirt4.3 and centos8/ovirt4.4), but the script exits with the
following error in some of them:
Traceback (most recent call last):
File "get_uuid.py", line 70, in <module>
storage_domain = sds_service.list(search='name=data-foo')[0]

raise error
ovirtsdk4.Error: Fault reason is "Operation Failed". Fault detail is "Can't
find storage server connection for id '92444a95-0be7-4589-ac46-1ed6dfe7ed4c'.".
HTTP response code is 500.
The portion of the script that search for the storage domain is the following:
sds_service = connection.system_service().storage_domains_service()
storage_domain =
sds_service.list(search='name={}'.format(storage_domain_name))[0]
Now: I have no real clue on which ID "92444a95-0be7-4589-ac46-1ed6dfe7ed4c'"
but digging in the engine logs it refers to StorageServerConnections ID:
[root@ovirt-engine ovirt-engine]# zgrep 92444a95-0be7-4589-ac46-1ed6dfe7ed4c

As I said, I tried to execute the script from several hosts: some of them with
oVirt 4.3 and other with oVirt 4.4 but it can run, or not, on both of versions.
I also did the following test: I tried execute the script on different host
passing different data storage:
- let's say that on host foo-host1, executing the script querying for its own
data storage named foo-data1 works correctly;
- and let's say that on host foo-host2, the same script querying for its own
data storage foo-data2 return the mentioned error;
If I execute the script on foo-host2 querying the foo-data1 domain data, I got
the error. If I execute on foo-host1 querying foo-data2, I still got the error.
When I try to manage the storage domain via ovirt-engine GUI on the hosts that
the script exit with the mentioned error, I recieve the following error:
Uncaught exception occurred. Please try reloading the page. Details:
(TypeError) : Cannot read property 'a' of null
Please have your administrator check the UI logs

Any slightest idea on what is going on?
Thank you for your time and help,
