Hello,
this was of course discussed here in the very recent thread
"data corruption with hammer"
Read it, it contains fixes and a workaround as well.
Also from that thread: http://tracker.ceph.com/issues/12814
You don't need to remove the cache tier to fix things.
And as also discussed here,
Help, my Ceph cluster is losing data slowly over time. I keep finding files
that are the same length as they should be, but all the content has been
lost & replaced by nulls.
Here is an example:
(from a backup I have the original file)
[root@blotter docker]# ls -lart
/backup/space/docker/ceph-m
