Where are those?
https://github.com/ceph/ceph/tree/master/doc/man/8
https://github.com/ceph/ceph/tree/master/doc/radosgw
don't seem to contain them in master. Nor in nautilus branch or octopus.

This whole issue feels weird, rgw (or its users) produces dead fragments of
mulitparts, orphans and whatnot that needs cleaning up sooner or later and
the info we get is that the old cleaner isn't meant to be used, it hasn't
worked for a long while, there is no fixed version, perhaps there is a
script somewhere with caveats. This (slightly frustrated) issue is of
course on top of
"bi trim"
"bilog trim"
"mdlog trim"
"usage trim"

"datalog trim"

"sync error trim"

"gc process"

"reshard stale-instances rm"



that we rgw admins are supposed to know when to run, how often, what their
quirks are and so on.


'Docs' for rgw means "datalog trim" --help says "trims the datalog", and
the long version on the web would be "this operation trims the datalog" or
something that doesn't add anything more.
