[Samba] MacOS clients - best options

[Thomas Hukkelberg]

Thank you Ralph for pointing to the Ceph issue -- I'll followup the Ceph bugreport now. We run Ceph 16.2.11 on Linux 5.13.19/6.2.9 with Samba 4.17.6 and experience this issue several times a day. If we copy 50 small files, about 5% remains grayed out.

However, when validating this issue I did an interesting finding -- the brokMACS sequence seems only to prevail on file types that are known to macOS, like png, pdf, wav etc. When copying files that have unknown or no extension I never see the brokMACS sequence. Could the fact that Finder reads back the file to generate previews somehow mess up the clearing of the brokMACS sequence?

Tobias, do you see the same behavior?
