Subject nodetool status Load not same with disk used
Date Thu, 29 Oct 2015 08:08:31 GMT
We have some nodes Load too large, but some are normal. 
[qihuang.zheng@cass047221 forseti]$ /usr/install/cassandra/bin/nodetool status
-- Address        Load    Tokens Owns  Host ID                             Rack
UN 2.66 TB  256   8.7%  87e100ed-85c4-44cb-9d9f-2d602d016038 RAC1
UN 614.58 GB 256   8.2%  91ad3d42-4207-46fe-8188-34c3f0b2dbd2 RAC1

I check the node with df command, and find disk used only 715G.
[qihuang.zheng@cass047221 forseti]$ df -h
Filesystem   Size Used Avail Use% Mounted on
/dev/sda2    20G 8.6G  11G 47% /
tmpfs      16G   0  16G  0% /dev/shm
/dev/sda1    190M  58M 123M 32% /boot
/dev/sda4    3.5T 715G 2.6T 22% /home

and this is a normal node’s disk used:
[qihuang.zheng@cass047204 ~]$ df -h
Filesystem      Size Used Avail Use% Mounted on
tmpfs         16G   0  16G  0% /dev/shm
/dev/sda1       485M  57M 403M 13% /boot
           3.4T 659G 2.6T 21% /home

How does nodetool status Load come from? should't It based on sstable file size which also
based on disk used?

Tks, qihuang.zheng
