> Volume failures detected on startup are not currently counted/reported as
> such. Eg if you have configured 4 volumes, 2 tolerated failures, and you
> start a DN with two failed volumes it will come up and report (to the NN) no
> failed volumes. The DN will still be able to tolerate 2 additional volume
> failures (ie it's OK with no valid volumes remaining). The intent of the
> volume failure toleration config value is that if more than this # of volumes
> of the total set of configured volumes have failed the DN should shutdown,
> therefore volume failures detected on startup should count against this
> quota.
