Hi Simone, The multipath health is built on VDSM start from the current multipath state, and after that it is maintained based on events sent by udev. You can read about the implementation details in [1].
It seems that in your scenario, either udev did not sent the needed clearing events or that Vdsm mishandled them. Therefore only restart of the Vdsm will clear the report. In order to be able to debug the issue, we will need Vdsm logs with debug level (on storage log) when the issue is happening.
