lcg-getturls doesn't work - and in fact on some versions of DPM it returns a URL that won't work .
I raised this with David Smith and attach his reply here - he has fixed the later issue in the latest DPM.
but rather than getting the turl in this way he is suggesting just that people use root://[headnode]//SURL ie a rexegp which is what ATLAS do.
I think that is the right way for LHCb to go - at least to have the option in dirac to do that - rather than asking the headnode for each request what the surl to turl conversion is when for (xrootd on ) DPM it just the same.
(PS we agreed that in the annecy (pre-)GDB )that a storage system either needed to supply a way to get the turl OR for the turl to be [PROTOCOL]://["SRM"node]//[SURL]
If they don't want to do then I guess they have to convince David to put the capability (back) in DPM.
