hello
I have a few osd's in my cluster that are regularly crashing.
in the log of them i can see
osd.7

ofcourse having 3 osd's dying regularly is not good for my health. so i
have set noout, to avoid heavy recoveries.
googeling this error messages gives exactly 1 hit:
https://github.com/ceph/ceph/pull/6946
where it saies: "the shard must be removed so it can be reconstructed"
but with my 3 osd's failing, i am not certain witch of them contain the
broken shard. (or perhaps all 3 of them?)
a bit reluctant to delete on all 3. I have 4+2 erasure coding.
( erasure size 6 min_size 4 ) so finding out witch one is bad would be
nice.
hope someone have an idea how to progress.
kind regards
Ronny Aasen
