As I said I haven't actually tested it, apart from that I have librbd working under Windows now ("rbd ls" and "rbd export" both work but I don't know if they actually do anything with uuid's...)
My patch to MStatfsReply.h to make it compile is:
diff --git a/src/messages/MStatfsReply.h b/src/messages/MStatfsReply.h
index 8ceec9c..40a5bdd 100644
--- a/src/messages/MStatfsReply.h
+++ b/src/messages/MStatfsReply.h
@@ -22,7 +22,7 @@ public:
MStatfsReply() : Message(CEPH_MSG_STATFS_REPLY) {}
MStatfsReply(uuid_d &f, tid_t t, epoch_t epoch) : Message(CEPH_MSG_STATFS_REPLY) {
- memcpy(&h.fsid, f.uuid, sizeof(h.fsid));
+ memcpy(&h.fsid, &f.uuid, sizeof(h.fsid));
header.tid = t;
h.version = epoch;
}
So assuming this actually works, the uuid bytes are accessible as per the above.
