Just to let folks know, we have a ceph vfs driver for samba that we are testing out now. We're planning to resolve a few of the bugs that we're seeing presently with smbtorture, and send a pull request to the samba repo. If anyone wants to help with testing, let us know. The changes currently reside in the ceph branch of http://github.com/ceph/samba. -slang [inktank dev | http://www.inktank.com | http://www.ceph.com] > > Cheers, > Kai > > - -- > Kai Blin > Worldforge developer http://www.worldforge.org/ > Wine developer http://wiki.winehq.org/KaiBlin > Samba team member http://www.samba.org/samba/team/ > -----BEGIN PGP SIGNATURE----- > Version: GnuPG v1.4.10 (GNU/Linux) > Comment: Using GnuPG with undefined - http://www.enigmail.net/ > > iEYEARECAAYFAlFUKl8ACgkQEKXX/bF2FpRjMwCghOWYnWX1RtxtygqcLYDES3EC > nXkAoIe0aPX5AA+mF1d0rf74s0+i4gVM > =aYfR > -----END PGP SIGNATURE----- > _______________________________________________ > ceph-users mailing list > ceph-users@xxxxxxxxxxxxxx > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
