I dug into this a little bit more. Apparently the default is 50GB.
On my datanodes, I ran df –hl. This is the output
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/centos-root 50G 12G 39G 23% /
devtmpfs 16G 0 16G 0% /dev
tmpfs 16G 0 16G 0% /dev/shm
tmpfs 16G 1.4G 15G 9% /run
tmpfs 16G 0 16G 0% /sys/fs/cgroup
/dev/sda2 494M 123M 372M 25% /boot
/dev/mapper/centos-home 2.7T 33M 2.7T 1% /home
If I’m reading this right it HAS to be mounted correctly because no other mount
points have enough space correct?

Could you double check that your datanodes are using the correct mount point?
Thanks,

It reports the space available for HDFS.

On the dashboard, what exactly is HDFS disk usage reporting? The numbers I’m
seeing are WAY less than the total disk space on my cluster.
