Hi, Here are a few more improvements to the qemu rbd support. The first patch makes the configuration file handling cleaner (do not error out if /etc/ceph/ceph.conf doesn't exist). One allows characters in the conf string to be escaped, so you can (for example) specify an ip\:port (':' is used as a delimiter). The last patch implements flush when rbd_flush() is available. This lets us take advantage of write buffering in newer versions of librbd, which improves performance significantly for many workloads (including the trivial qemu-img convert). Thanks! sage Sage Weil (4): rbd: ignore failures when reading from default conf location rbd: allow escaping in config string rbd: update comment heading rbd: call flush, if available block/rbd.c | 83 +++++++++++++++++++++++++++++++++++++++------------------- 1 files changed, 56 insertions(+), 27 deletions(-) -- 1.7.2.5 -- 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
