Big Data Appliance Integrated Software - Version 2.1.0 and later
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.
Firmware state: Unconfigured(bad)
Foreign State: Foreign
Foreign Secure: Drive is not secured by a foreign lock key
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.
Bug 18139689 - BDA DOES NOT RAISE ASR EVENTS FOR ALL UNHEALTHY DISK STATES
