what is the status from ambari GUI that approve all datanode disks are ok

[#1]

we have ambari cluster ( version 2.6 ) with 3 workers machines ( datanode machines )

each worker machine have now 10 disks ( after we add 5 disks on each worker machine )

how to identify from ambari GUI that all disks are ok and ambary recognize the disks size ?

df -h from worker machine

Ambari itself doesn't know those disks are mounted until you edit the host configurations for HDFS/YARN and update the data directory configurations.

The Ambari Alert check will run periodically to see if those configured disks are mounted, then the agent will update the dashboard.
