Dear all, I have a question, related to the CMS xrootd Federation that is currently being established. We currently have an storage element (dcache) with a normal authenticated xrootd door (storage01), and files inside the CMS namespace are named this way: /pnfs/lcg.cscs.ch/cms/trivcat/this/is/my/file And we have installed an xrootd redirector in another host (not inside the dcache cluster) as specified here: https://twiki.cern.ch/twiki/bin/view/Main/CmsXrootdArchitecture And this redirector is called cmsvobox. That host registers files into a xrootd manager, striping out the site location from the filename, so files look like /this/is/my/file. And the idea is that an external client can then connect to our redirector and ask for: cmsvobox:/this/is/my/file And that should be redirected to our xrootd dcache door (storage01) to the file: storage01:/pnfs/lcg.cscs.ch/cms/trivcat/this/is/my/file Redirect works, but we can't make it so that cmsvobox redirects *and adds* the missing part of the filename. cmsvobox xrootd relevant config looks like this: all.manager xrootd.ba.infn.it:1213 oss.localroot /pnfs/lcg.cscs.ch/cms/trivcat xrootd.redirect storage01.lcg.cscs.ch:1094 / all.export / nostage readonly oss.namelib /usr/lib64/libXrdCmsTfc.so file:/etc/xrootd/storage.xml?protocol=direct And the relevant part of storage.xml: <lfn-to-pfn protocol="direct" destination-match=".*" path-match="/+store/PhEDEx_LoadTest07/LoadTest07_[^/]+_CSCS/[^/]+/[^/]+/(.*)_.*_.*" result="/pnfs/lcg.cscs.ch/cms/trivcat/store/phedex_monarctest/monarctest_CSCS-DISK1/$1"/> <lfn-to-pfn protocol="direct" destination-match=".*" path-match="/+(.*)" result="/pnfs/lcg.cscs.ch/cms/trivcat/$1"/> <pfn-to-lfn protocol="direct" destination-match=".*" path-match="/pnfs/lcg.cscs.ch/cms/trivcat/(.*)" result="/$1"/> I have to admit I am not an xrootd expert, so any help would be really appreciated! Thanks, BR/Pablo PS: There may be an easy way out: creating a separate dcache xrootd door, with a different port and a fake root /pnfs/lcg.cscs.ch/cms/trivcat, and point the redirector to it... but it seems to me much more dirty, compared with a generic xrootd (that could equally serve ATLAS and CMS both) and a good name translation mechanism. ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the XROOTD-L list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=XROOTD-L&A=1
