Windows port

[Cesar Mello]

Hi,

Is there interest in a Windows port?

Thank you for the attention.

Best regards
Cesar

Hi,

I have been playing with ceph and reading the docs/thesis the last
couple of nights just to learn something during my vacation. I was not
expecting to find such an awesome and state of the art project.
Congratulations for the great work!

Please I would like to know if a Windows port is imagined for the
future or if that is a dead-end. By Windows port I mean an abstraction
layer for hardware/sockets/threading/etc and building with Visual C++
2012 Express. And then have this state of the art object storage
cluster running on Windows nodes too.

Thank you a lot for the attention!

Best regards
Mello

Hi,

I am also curious if a Windows port, specifically the client-side, is
on the roadmap.

This is not super-likely (although it's not impossible either).
Inktank is a long way from doing the necessary development for this —
we don't have any Windows developers on staff. External contributors
who are interested in doing the work themselves would certainly get
some support in doing so, but I can't even begin to estimate the size
of the project that would be required. Would a simple abstraction
layer be able to provide the right interface with anything approaching
acceptable performance? I really don't know.

This is somewhat more likely than porting the servers, but again we at
Inktank don't currently have the expertise necessary. It'd be a lot
easier if there were a FUSE for Windows; that's how we'll be getting
an OS X client.

I think this also depends on the scope of the effort - what portions of
ceph are ported to Windows.  I have to confess that I do not see a lot
of value in porting the OSD, MDS, and MON daemons to Windows.  This just
doesn't make a lot of sense - if you're setting aside machines
specifically for a distributed filesystem, why not just run Linux?  The
piece that I can see being useful in a Windows port is actually just the
filesystem client.  I have cases where it would actually be really,
really nice to be able to mount my ceph filesystem natively on
Windows-based machines.  I think this type of effort is much more
manageable (warning: that's the ignorant opinion of an IT manager, not a
skilled developer ;-) - it seems that porting the FUSE Ceph client over
to something like Dokan (user mode filesystem on Windows, FUSE
look-alike) might be a feasible task.  I do understand that InkTank is
more interested in building out the existing system on the existing
platforms, but Cesar, Dino, if you're interested in a Windows port of
the ceph client, porting the FUSE client over to Dokan might be a good
place to start.

This is somewhat OT from the original post, but if all you're
interested is using RBD block storage from Windows, you can already do
that by going through an iSCSI or FC head node. Proof-of-concept
configuration outlined here:

Not sure if this helps, but just thought I'd mention it.

Cheers,
Florian

There is also a patch for Samba that glues libcephfs into Samba's VFS 
layer.  This will let you reexport CephFS via CIFS.  These patches are 
currently living at

	https://github.com/ceph/samba/commits/ceph-v3-6-test

If anybody is interested in playing with these, have at it!  Inktank 
doesn't have resources to focus on it right now.

Hi,

Along the same lines, (p)NFS access from Windows clients should already be possible, for some definition of possible.  We'll make it actually possible over the next few months.
