Maybe.... I've marked the object as "lost" and removed the failed OSD.
The cluster now is healthy, but I'd like to understand if it's likely to bother me again in the future. Yeah, I don't know.
Within the last month there are 4 separate instances of people mentioning "unfound" object in their cluster. I'm deferring as long as possible any OSD drive upgrades. I ran into the problem when "draining" an OSD. "draining" means remove OSD from crush map, wait for all PG to be stored elsewhere, then replace drive with larger one. Under those circumstances there should be no PG unfound. BTW, are you using cache tiering ? The bug report mentions this, but some people did not have this enabled. Chad.
