Fix Recommendation

Either remove all files and directories from the system that do not have a valid group, or assign a valid group to all files and directories on the system with the "chgrp" command:

# chgrp <group> <file>

Check Contents

Verify all files and directories on the system have a valid group.

Check the owner of all files and directories with the following command:

Note: The value after -fstype must be replaced with the filesystem type. XFS is used as an example.

# find / -fstype xfs -nogroup

If any files on the system do not have an assigned group, this is a finding.
