Did you manage to resolve this issue? From what I see in your steps below, it
looks like you're doing things in the wrong order -- mkcephfs should always be
the first thing you do. If you really have nodes running before you do mkcephfs
I suspect you

Hi,
I was browsing PG management code in Ceph, and have one question.
It appears that an OSD could send a PG removal request to another OSD.
The recipient OSD would then remove that particular PG from its pg_map.
I'd like to know

Huh.. that is pretty weird. I see multiple sync in there, too, so it's
not like something was somehow blocking on a btrfs commit.

You can try cherry-pick commit 9c3db35 off the ceph git. It is just a
temporary workaround, and it wasn't tested too

Based on what you've told us it looks like maybe you're running into a
btrfs bug of some kind.
We're working on getting the most recent version of btrfs onto some
nodes here to check it out as we've been hearing about sync issues
with btrfs for a few days now, but we haven't managed it yet.
