Exotic issues with pdfs on smb shares - Macos

[tiberiusQ]

Hi all,

Mac users report me that they get exotic error messages while opening pdf files on Truenas smb shares = unable to open ( preview and acrobat. ) or rename or copy.
Windows users are able to open, rename, copy those files.

I was able to reproduce and I really never saw such a poetic error messages and have no idea except one, the smb path to the file contain spaces and the file contains umlaute (eg. ü).

Open error:

Copy error:

Any Ideas - Thx and Best 1

Yeah, MacOS basically hard-codes certain unicode normalization style so if another client writes with different normalization, MacOS clients will not be able to properly interact with it.

How to deal with it ?

You can look into using the convmv tool.

This isn't a TrueNAS bug since same can be reproduced on a Windows SMB server. It's an old MacOS client issue.

Ahh got it thx !

So conversion /renaming/ is the solution with eg. convmv right ?

Right. Potential information loss is about file name (not file data).

Add. what exactly does it, will there a convmv command applied on already present datasets/shares and how will this affect windows and linux users ?

@anodos ?
