You can do IO to a rbd image, but it currently does a queue depth of only 1. We are in the process of merging patches from a couple branches to add rbd aio support, failover/failback across gateways, perf improvements, and lots of bug fixes. With them, linux works well, and we are working on a couple windows bugs. For ESX, we are hoping to be ready around the end of summer. You should not use ESX with tcmu/tcmu-runner right now, because several commands are not implemented or implemented incorrectly for ESX. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
