I am not sure that is going to work, because I have this error quite 
some time, from before I added the 4th node. And on the 3 node cluster 
it was:
 
osdmap e18970 pg 17.36 (17.36) -> up [9,0,12] acting [9,0,12]

If I understand correctly what you intent to do, moving the data around. 
This was sort of accomplished by adding the 4th node.

try to restart osd.29, then use pg repair. If this doesn't work or it 
appear again after a while, scan your HDD which used for osd.29, maybe 
there is bad sector of your disks, just replace the disk with new one.

        I thought I will give it another try, asking again here since there 
is 
        another thread current. I am having this error since a year or so.
        
        This I of course already tried:
        ceph pg deep-scrub 17.36
        ceph pg repair 17.36
        
        
        [@c01 ~]# rados list-inconsistent-obj 17.36 
        {"epoch":24363,"inconsistents":[]}
        
        
        [@c01 ~]# ceph pg map 17.36
        osdmap e24380 pg 17.36 (17.36) -> up [29,12,6] acting [29,12,6]
