issue with Log Directory Free Space , This role's log directory is on a filesystem with less than

[#1]

Hi 

I am facing critical warning on CDH manager interface for log directory  

This role's log directory is on a filesystem with less than 5.0 GiB of its space free. /var/log/hadoop-hdfs (free: 119.0 MiB (0.24%), capacity: 49.1 GiB).While on my system I can see I have the root directory filled , but i do have space in home directory. 

I would like to know how and what prorpoerty i need to chnage to make log to /home instead of small root . i didn't get any link to fix this issue ,if you can just point me to write info it will be really helpful here 

[root@hadoop-vm2 subdir0]# df -h

Visit any service's configuration page. In the search box, type in
"logging". This will show you all the locations where log files are
written for this service. Make the changes you wish to and restart the
roles. Ensure that every relevant host on the cluster has this new
directory created and the filesystem permissions are correct.

Hi Gautam

My issue is I think with filled space , after troubleshooting i found i was earlier using /dfs/dn for HDFS block storage , later i added non OS partition under /home (/home/hdfs/dfs/dn) and then started importing  100 of GB data.  Looks like some how my old path /dfs/dn had also sotred some of HDFS blocks and filled that root partition. Sais so if now by chnagging the configuration  remove (/dfs/dn)  dfs.data.dir  and restart cluster will it do automatic move data to only left location /home/hdfs/dfs/dn or how to handle that. I guess this will fix my problem for now.

Do not worry about data much what ever best and quick will be fine .
