Off the wall suggestion. Instead of changing XFS to suit Samba, layer
another filesystem over XFS that converts all names to lower case and
provide that filesystem view to Samba. Such a layered filesystem for
converting to lower case already exists, locasefs as part of the LUFS
No XFS disk format changes.
No XFS work at all :-))
Works for all filesystems, not just XFS.
Extra copies of the data (XFS -> LUFS -> SAMBA), acceptable when the
network and/or the Windows machines are the bottleneck.
LUFS filesystems cannot be NFS exported yet, and I do not know if the
NFS restrictions on LUFS layers will affect Samba or not. OTOH I have
a vested interest in making LUFS layers work over NFS so I expect that
problem to be solved fairly soon.
From the locasefs source comments:
Win32 filesystem is basically case insensitive.
Casing in file names is supported, but not relevant when opening
files, a case insensitive matching is performed. If working with
source code obtained from win32 on *nix systems, you often have to
manually convert into a lowercase-only tree to be safe
Getting into a more complicated situation where the *nix version
has to interoperate with the win32 source, without the ability to
change all the casing to be correctly lowercase in the win32 master
Provide a lowercase mapping of a filesystem (read/write).
There are probably several operating options, such as supporting a
case-sensitive filesystem a-la-win32, mapping to uppercase, mapping
to lowercase ..
get the lowercase mount as a flag over regular localfs?
NOTE: what happens if root has something like: File and file in
same dir? first found will be selected
