In my test environment I changed the reweights of an osd. After this
some PGs get stucked in 'active+remapped' state. I can only repair it by
stepping back to the old value of the reweight.
Here is my ceph tree:
> # id weight type name up/down reweight
> -1 12 root default
> -4 12 room serverroom
> -2 12 host test1
> 0 2 osd.0 up 0.7439
> 1 2 osd.1 up 0.9
> 2 4 osd.2 up 1
> 3 4 osd.3 up 1
> -3 0 host test2
I changed osd.1 from 1.0 to 0.9 and then this happened:
> :# ceph health detail
> HEALTH_WARN 10 pgs stuck unclean; recovery 94/2976 objects misplaced
(3.159%)
> pg 6.4 is stuck unclean for 1135.549938, current state
active+remapped, last acting [1,2,3]
> [...]
ceph pg dump shows the primary OSD of PG 6.4 as not existent (MAXINT). I
do not have any idea what happend here.
Pool 6 is an erasure coded pool (k=2, m=1). Here is the last part of the
query output from the first PG 6.4:
> :# ceph pg 6.4 query

Any idea what happened or have I done anything wrong here?
