Thanks for the pointers Dave. That got me to compiling the module.
I'm still using the RPM-installed GlusterFS and Samba, but have
compiled/installed matching source versions into a --prefix=/localdev
folder and used that to build the samba-glusterfs-vfs module with
relevant paths during the "./configure" step.
The module was copied to /usr/lib64/samba/vfs, vfs_glusterfs.so was
symlinked to glusterfs.so, and appears to be working.
Relevant smb.conf
[sharename]
vfs object = glusterfs
glusterfs:volume = volumename
path = /
Testing so far has been much faster for read/browse operations, so
that much is good.
However, bugs that already make it unusable for me at the moment:
* renaming files and folders from a Windows host gives a "does not
exist" error in the Explorer GUI, and a "duplicate filename exists"
error from cmd.exe.
* Brick logs fill up with 4 lines of "getxattr failed" messages for
each file or folder read, and this is with all GlusterFS error log
levels already set to "critical". With a network full of users, I'm
going to fill disks with logs in minutes. I had seen this reported in
3.3.1 and marked as fixed in 3.4.0, but it appears to still be around.
I have XFS formatted disk backing each brick with 512 byte inodes and
default mount options. I don't wish to turn on user_xattr, as I want
to just discard any of that sort of data coming from Mac and Windows
hosts, as it's unnecessary for our production data. But at the same
time, I don't want GlusterFS telling me it's an error when it's not
there (INFO level would suffice, so I can ignore that in my logs).
