[jira] Commented: (HADOOP-4680) fuse-dfs - df -kh on hdfs mount shows much less %used than the dfs UI

["Pete Wyckoff (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-4680?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12648797#action_12648797 ] 

Pete Wyckoff commented on HADOOP-4680:
--------------------------------------

just another note - this is only the % used seems to be off:

{code}
Filesystem            Size  Used Avail Use% Mounted on
      fuse                  20P  18P  1.1P  46% /export/hdfs
{code}

46% is clearly way off - should be more like 95% or so.

> i.e., statfs broken.
> This used to show the correct amount and now is showing wrong numbers in  production environment.
> Yet, the unit test for this passes??
> This is the trunk version of fuse-dfs against 0.17 libhdfs and hadoop.
> Unknown if this affects 0.18.2 or 19.1 or trunk but i suspect it does. 
> admittedly fuse-dfs isn't supported against hadoop 17 but I am confident that it is likely broken in all versions.
