Hi, ceph. We are pleased to announce our first milestone in bringing Ceph to the Windows platform, by porting librados into rados.dll. https://github.com/AcalephStorage/rados_dll Many thanks to dketor@xxxxxxxxx and the ceph-dokan project for providing the springboard and early consultation with which we were able to embark upon this course (we've also forked ceph-dokan and are looking to be active contributors to that project). ### Overview * rados_dll is built using mingw, like ceph-dokan * Currently, it builds rados.dll, used by rados_client.exe * rados.dll provides the librados C API (linking C++ using .DLLs is problematic) * rados_client.exe follows example code here (http://ceph.com/docs/master/rados/api/librados-intro/) to drive rados.dll, connect to a Ceph cluster and perform I/O * LGLP v2.1 ### Details Currently, rados_dll is built, similar to ceph-dokan, from source files copied over from ceph/src and with _WIN32 specific modifications. It is built using gcc, and uses winsock. ### Next steps We've had to disable cephx authentication for now, obviously we need to get this ported and working properly. Currently, the build environment has to be carefully prepared by hand. We're looking to add scripts to help ease and automate that process. We're looking to streamline merging of changes from 'upstream' ceph. First, we intend to remove unmodified source files from the src/ directory and use upstream ceph/src directly. Next, we're looking to use tools (e.g. diff/patch, sed) to the apply _WIN32 specific modifications in an automated manner whenever possible to generate _WIN32 sources. We hope to gain enough traction and credibility to contribute _WIN32 specific sections (with appropriate guards) to ceph core code. Eventually, hopefully, we might be able to build rados.dll (along with other Ceph components that can be ported to Windows) directly from a single set of source files. Finally, our Makefile is hand-written (as with ceph-dokan), and we welcome any help to be able to standardise on using the autotools toolchain to automate that as well (or integrate with upstream). ### Roadmap We're looking at tackling RBD soon, and provide a native, Windows system-level block device backed by Ceph. ;) We welcome any and all comments, suggestions, and support. ### Who we are Acaleph is a small startup headquartered in Singapore, but operating mostly from the Philippines, and we provide Ceph deployment, integration, support and other services. Julio Telan is a graduating student from De La Salle University spending his internship at Acaleph, mentored by yours truly. Cheers! Alistair A.
