Symptoms

When a HDFS disk goes bad and unmounted (perhaps by a reboot) on one of the Oracle Big Data Appliance (BDA) nodes, /root file system gets filled up by HDFS data.

Slot Number: 11
Firmware state: Unconfigured(bad)
Foreign State: Foreign
Foreign Secure: Drive is not secured by a foreign lock key

 

Changes

Disk went bad, but ASR didn't fire an SR due to internal Bug 18139689.  Reboot has been performed on the node and as the disk is bad, it got unmounted during startup.
