      Description

      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.
