Yes, I have already had #4 (that I "fixed" for testing by truncating to 20 chars the image name in ganeti); I am running ceph 0.39 and will switch to git master if I encounter some of these problems: thanks for the suggestion. > I should also note, that we use ext4 (and not btrfs) as the underlying > filesystem for the OSDs. Why are you using ext4? For what I understand, it seems like rados is designed to take advantage of btrfs features. Also, can you please tell me the Ganeti revision on which you based your patch? >> I will post a detailed patch review after testing it, but before >> please fix the issues that "make lint" will give you (there are a >> couple of them). > > Constantinos will follow-up with an e-mail about the RBD disk template > patchset. Great! Thanks, Andrea
