Doc Text:	.Certain maintenance image operations are no longer incorrectly allowed on non-primary images With RADOS Block Device (RBD) mirroring enabled, non-primary images are expected to be read-only. Under certain conditions, the `rbd` command did not properly restrict `rbd` maintenance operations against non-primary images. The affected operations included: * updating snapshots * resizing images * renaming and creating clones using the non-primary image as the parent With this update, these operations are disallowed on non-primary images as expected.

Description Tanay Ganguly 2016-06-22 06:43:29 EDT

Description of problem:
Observed a Crash while Parent and Clone image are getting synced on the Slave Node. The mirror daemon crashed and again got restarted.

Version-Release number of selected component (if applicable):
10.2.2-5.el7cp.x86_64

How reproducible:
Once

Steps to Reproduce:
1.Executed the attached script.
   The Script does:
   Create Image with Journal enabled, take Snap, Protect Snap, Clone it with Journal enabled, unprotect snap,bench write on Clone, bench write on parent image.

Actual results:
Passed 4 iteration, failed in 5th Iteration (PFA, Script)

Expected results:
No Crash and Clone should sync completely.

Additional info:

Note: There was another sync on a different image named: bigimage1 (100GB) with complete data on it was also going on.

Following list gives the % synchronization complete on Slave Node at the time of Crash:

bigimage1 -- 1ebacfa8-fa2b-4c0a-8d38-56cbbee90507  COPY_OBJECT 70%   
liver5    -- ef4e2d9e-5d1c-4a58-87cf-edb46f43f242  COPY_OBJECT 72%
liverClone_new5 -- f40b86df-236c-4e63-b30d-24570a66ce79	COPY_OBJECT 44%
