Serving LFS files can experimentally be turned off.  The long term solution is

to support the 'verify' action in both client and server, so that the server can

tell the client to store files elsewhere.

  $ hg init server

  $ hg --config "lfs.usercache=$TESTTMP/servercache" \

  >    --config experimental.lfs.serve=False -R server serve -d \

  >    -p $HGPORT --pid-file=hg.pid -A $TESTTMP/access.log -E $TESTTMP/errors.log

  $ cat hg.pid >> $DAEMON_PIDS

Uploads fail...

  $ hg init client

  $ echo 'this-is-an-lfs-file' > client/lfs.bin

  $ hg -R client ci -Am 'initial commit'

  adding lfs.bin

  $ hg -R client push http://localhost:$HGPORT

  pushing to http://localhost:$HGPORT/

  searching for changes

  abort: LFS HTTP error: HTTP Error 400: no such method: .git (action=upload)!

... so do a local push to make the data available.  Remove the blob from the

default cache, so it attempts to download.

  $ hg --config "lfs.usercache=$TESTTMP/servercache" \

  >    --config "lfs.url=null://" \

  >    -R client push -q server

  $ mv `hg config lfs.usercache` $TESTTMP/servercache
