If it is set to “sensitive”, will w11 over SMB be OK with this share?
Is it a big deal, that setting?? The dataset has never been shared or even accessed except thru SMB.
Case sensitivity varies by OS
Linux and FreeBSD are by default. Ditto ZFS.
Mac OS may or may not be case sensitive, depending on how the drive was formatted. Default is not with APFS or the older HFS+.
Windows is not case sensitive by default. But it can be selectively turned on depending on the version of windows you’re using.
Bottom line, it really depends on what you’re trying to do? See this prior discussion.
“Family vacation” and “Family Vacation” are considered the same folder.
“Cake recipes.docx” and “Cake Recipes.docx” are considered the same file.
While such files and folders can coexist in the underlying ZFS dataset (filesystem), they cannot under an SMB share.
If you try to create a new folder or file, you will be hit with the error message “File already exists”, even if they differ in case.
