Doc Text:
.Error messages are no longer returned after disabling journaling When the `journaling` feature was disabled on an image that was previously mirrored by the `rbd-mirror` daemon, an error message similar to the following was returned on the primary cluster: ---- 2016-06-15 22:10:40.462481 7fed3d10b700 -1 rbd::mirror::ImageReplayer: 0x7fecd8003b80 [1/29d86f79-7bba-4316-9ab9-c8a3f600e0f2] operator(): start failed: (2) No such file or directory ---- These harmless error messages indicated that the image journal was deleted because `journaling` was disabled. The underlying source code has been modified, and the error messages are no longer returned in the described situation.
