Handling Disk Failures
Explains how to handle disk failures.
When a disk fails, Data Fabric raises the node-level alarm
NODE_ALARM_DISK_FAILURE
on the node with the failed disk (or disks). At the
same time, other disks in the same storage pool as the failed disk are taken offline. You can
look at the Control System Overview page to view the health of the
nodes and a list of alarms.
When you see a disk failure alarm, examine the log file at
/opt/mapr/logs/faileddisk.log
and check the Failure Reason field.
