How to delete unseen linux large file?

[darrenfu]

There were two cases we met:

• Storm worker log file
• graphite log file

Find and remove large files that are open but have been deleted on Linux or Unix:

## Works on Linux/Unix/OSX/BSD etc ##
lsof -nP | grep '(deleted)'    
## Only works on Linux ##
find /proc/*/fd -ls | grep  '(deleted)'

To truncate it:

 ## works on Linux/Unix/BSD/OSX etc all ##
> "/path/to/the/deleted/file.name"
## works on Linux only ##
> "/proc/PID-HERE/fd/FD-HERE"
