Hi,

  after rebooting SAN switches we see faulty multipath entries in VDSM.

Running vdsm-client Host getStats shows multipathHealth entries

"multipathHealth": {
  "3600601603cc04500a2f9cd597080db0e": {
    "valid_paths": 2,
    "failed_paths": [
      "sdcl",
      "sdde"
    ]
  },
  ...

Running multipath -ll does not show any errors.

After restarting VSDM, the multipathHealth entires from vdsm-client are emp=
ty again.

Is the a way to clear those multipathHealth entires without restarting VDSM=
?

Thank you and all the best,
Simone
