Hello. I was have one-way multisite S3 cluster and we've seen issues
with rgw-sync due to sharding problems and I've stopped the multisite
sync. This is not the topic just a knowledge about my story.
I have some leftover 0 byte objects in destination and I'm trying to
overwrite them with Rclone "path to path". But somehow I can not
overwrite these objects. If I delete with rclone or rados rm and do
rclone copy again, I got the result below. Rclone gives error but the
object is created again "0 byte" with pending attrs. Why is this
happening?
I think somehow I need to clean these objects and copy from source
again but how?
What is "user.rgw.olh.pending" ?
