Re: [gpfsug-discuss] Policy scan of symbolic links with contents?

Mon, 08 Mar 2021 08:08:03 -0800

Presumably the only feature that would help here is if policy could determine that the end location pointed to by a symbolic link is within the current file system.  I am not aware of any such feature or attribute which policy could check so I think all you can do is run policy to find the symbolic links and then check each link to see if it points into the same file system.  You might find the mmfind command useful for this purpose.  I expect it would eliminate the need to create a policy to find the symbolic links.

Well - the case here is that the file system has, let’s say, 100M files. Some percentage of these are sym-links to a location that’s not in this file system. I want a report of all these off file system links. However, not all of the sym-links off file system are of interest, just some of them.

 

I can’t say for sure where in the file system they are (and I don’t care).

Could you use the PATHNAME LIKE statement to limit the location to the files of interest?

Looking to craft a policy scan that pulls out symbolic links to a particular destination. For instance:

 

file1.py -> /fs1/patha/pathb/file1.py (I want to include these)

file2.py -> /fs2/patha/pathb/file2.py (exclude these)

 

The easy way would be to pull out all sym-links and just grep for the ones I want but was hoping for a more elegant solution…
