Hello,
I have been using Robinhood 3.1-1 to cleanup old files from our scratch file
systems but when adding a rmdir policy to remove empty directories it is not
working. Scanning the file system with a fresh database populates the target
fileclass as expected and the database entry-info for the directories seems to
fit my policy deletion rules. However, when running the policy, it completes
successfully but without removing any directories. This is how I am running the
policy:
[xctrh00:~]$ sudo robinhood -f test --run=rmdir --once
When running the policy with log verbosity level DEBUG or FULL the directories
within the target fileclass are not in the output.
I have appended the configuration file below - any help with this would be
appreciated.
Many thanks
Doug
