xrootd door/mover does not detect filesize mismatch #2021

Closed kofemann closed 2 years ago

kofemann commented 8 years ago

On upload, xroot client (at lease for ALICE) can provide file size. Nevertheless dCache ignores it and does reflect in billing log if provided value mismatched received file size.

xrootd request:

open[X,Y,/path/to/file.root,authz=...&oss.asize=834908160]

billing log

That attribute is not part of the xrootd spec, but we may add support for it.

Probably we just ignore it, as this is only a hint : http://xrootd.org/doc/prod/ofs_config.htm#_Toc327979849

Will not implement.
