if fails and object already exists then retry. This improves first obj write performance on the expense of overwrites. Fixes: http://tracker.ceph.com/issues/18622 Signed-off-by: Yehuda Sadeh <yehuda@redhat.com> (cherry picked from commit 6f27f60)
Instead of this for overwrites: prepare (index), write (head) [-EEXIST] cancel (index) read (head) prepare (index) write (head) complete (index) We now do: prepare (index), write (head) [-EEXIST] read (head) write (head) complete (index) Signed-off-by: Yehuda Sadeh <yehuda@redhat.com> (cherry picked from commit 7f4818f)
