Tanya, Thanks. I am aware of that page, however (1) is isn't clear to me that xrootdfs supports user_xattr, which the instructions on the page require and (2) I have seen some indications (eg, http://indico.cern.ch/getFile.py/access?subContId=0&contribId=16&resId=1&materialId=slides&confId=71428 ) that suggest there is some native support for checksums. I have not seen anything definitive on either of these two. -paul > > ----- Original Message ----- > Hi, > > Check if this helps: > https://twiki.grid.iu.edu/bin/view/Storage/BestmanAdler32Checksum > > Thanks, > Tanya > > From: "Paul T.
