Are these fixes going to make it into the repository versions of ceph,
or will we be required to compile and install manually?

Yeah, that's definitely something that we'd address soon.

Subject: Re: [ceph-users] Shadow Files
Definitely need something to help clear out these old shadow files.
I'm sure our cluster has around 100TB of these shadow files.
I've written a script to go through known objects to get prefixes of
objects
that should exist to compare to ones that shouldn't, but the time it
takes
to do this over millions and millions of objects is just too long.

When these are fixed it would be great to get good steps for listing /
cleaning up any orphaned objects. I have suspicions this is affecting
us.
