get-disk-safety failed with 'Namespace manager exception: Nsm_model.Err.Namespace_id_not_found'.

[JeffreyDevloo]

Problem description

Monitoring revealed the following sub awesome behavior with the get disk safety command:

CRIT - EXCEPTION HC000 - Could not fetch alba information for backend nvmebackend Message: Command 'get-disk-safety' failed with 'Namespace manager exception: Nsm_model.Err.Namespace_id_not_found'.

What could have happened:

• Another healtcheck was busy with a test that involves creating and removing namespaces
• At the time the other namespace was getting deleted, get-disk-safety was called

Proposed solution

The whole command should not fail when one namespace cannot be fetched. Perhaps return the current output you have collected and add an exception section or something?

Which alba version?
I think this is something that should be fixed in 1.3.7, see #633 .

The alba version is 1.3.7
