> Say a DataNode (uuid:xyz) has disks D1 and D2. When D1 turns bad, JMX query on FSDatasetState-xyz
for "NumFailedVolumes" attr rightly shows the failed volume count as 1 and the "FailedStorageLocations"
attr has the failed storage location as "D1".
> It is possible to add or remove disks to this DataNode by running {{reconfigure}} command.
Let the failed disk D1 be removed from the conf and the new conf has only one good disk D2.
Upon running the reconfigure command for this DataNode with this new disk conf, the expectation
is DataNode would no more have "NumFailedVolumes" or "FailedStorageLocations". But, even after
removing the failed disk from the conf and a successful reconfigure, DataNode continues to
show the "NumFailedVolumes" as 1 and "FailedStorageLocations" as "D1" and it never gets reset.
