Thank you for posting.
This seems to be related to operating system permissions, although the ones you've listed appear correct.
Is Server HD the OS drive? Generally FileMaker Server installs to /Library/FileMaker Server. Can you verify that /Volumes/Server HD/ isn't read-only by running the mount command from terminal?
Are you able to manually create folders or copy files to this directory instead of using the Admin Console to upload the database?
Lastly, in the Admin Console under Configuration > Database Server > Default Folders it's possible to add an additional database folder. Does this allow you to get around the error or is it occuring at some other time?
Yes Server HD is the hard disk name and the path does not seem right to me either. its not mounted read only and i can create files and folders by hand, if i use /Lib or /Volumes/Server HD at the start of the path. I could not add any new path to the server with out using Server HD at the start as /Lib failed Validate . But this did get me thinking so i uninstalled FMS then removed the remaining files and folders with rm, renamed the local HD to pamac and rebooted the machine.
a reinstall of FMS then gave me a path of filemac:/pamac/Library/FileMaker Server/Data/Databases and the upload now works fine
Thanks for your help i will now be going ahead with ordering the full product :-)
