The script for Linux file system is:
df -lP 2>&1 | grep -v "df: ./root/.gvfs.*Permission denied" --
and for Linux file system include NFS is:
df -P 2>&1 | grep -v "df: ./root/.gvfs.*Permission denied" --
It is possible to configure Spotlight on Unix to use only local check anytime. Please perform the following steps:
The script is stored in {Spotlight on Oracle folder}\Plug-ins\DatasourceUNIX\Unix.xml, however, the command there is encrypted so it is not possible to change them.
A workaround is to update the template to always use file system script, to do that:
1. Open {Spotlight on Oracle folder}\Console\Templates\SoU.stx with a text tool;
2. Replace all “FileSystemsIncNFS” with “FileSystems”, there are 12 occurrences.
3. Save and reopen Spotlight, check the file drill down if take effect.
Please don't remember to backup the SoU.stx file before any change.
