Symptoms
An Oracle Big Data Appliance (BDA) node shuts itself down on its own almost everyday. When it goes down, it needs to be rebooted from ILOM.
To check an individual node to see if NUMA is enabled run the following commands:
# grep -i numa /var/log/dmesg
AND
# numactl --hardware
To check if NUMA is enabled on all nodes of the BDA cluster run from Node 1 as root:
# dcli -C grep -i numa /var/log/dmesg
# dcli -C numactl --hardware
# dcli -C numactl --hardware
The following is an example of output showing NUMA is disabled:
