Some notes and interspersed chatlog from the meeting: Sam Skipsey Wahid Bhimji Winnie Lacesso Rob Fay Elena Ewan John Bland Raja Raul Matt Doidge Steve Jones Robert Frank David Crooks Gareth Roy - Raja - alert - an issue with dCache (latest update), which causes issues for LHCb storage use. Keeps SRM turls open for a long time, causes the open slots to be exhausted, and the srm runs out of slots. Caused by update to dCache that tweaks open times - discussed in several GGUS tickets. This issue will last for a few weeks, until we have put into production a means of avoiding querying TURLS without accessing the SRM. - Winnie asked about DPM-on-HDFS. (Discussion of deployment of the And the availability of the xrootd/fax solutions. [ Paige Winslowe Lacesso: (18/03/2015 09:56) Sorry, what? As usual, am multitaskinh@ s/inh@/ing/ Q: Has anyone experimented w/DPM-Lite, like you Storage-experimental people who supposedly have time to experiment? And written it up?? Samuel Cadellin Skipsey: (10:04 AM) Winnie: *everyone with a DPM > 1.8.3* has dmlite. Paige Winslowe Lacesso: (10:07 AM) Think so we'll be using hdfs Ewan Mac Mahon: (10:09 AM) Are we sure this is a good idea? All things considered I think the better experimental approach to storage to try at Bristol is the not having any and going all FAX/AAA. Paige Winslowe Lacesso: (10:10 AM) Doesn't a site need an SRM-SE? Ewan Mac Mahon: (10:11 AM) Not if you're not giving them any storage. They should be able to run CPU only. AKA 'do a UCL' Paige Winslowe Lacesso: (10:11 AM) No, we're a CMS T2, will have to find out what they say about "not needing an SRM" for T2. wahid: (10:11 AM) In this pre-GDB - the experiments outlined their position https://indico.cern.ch/event/319817/ ] - PreGDB discussion DataBridge. We're not sure if this is actually a thing we should deploy at T2s, but the solution to connecting X509 to username/password auth mechanisms looks generally useful. - Wahid is off to NERSC. [ CAKE Likewise sorry ! Ewan Mac Mahon: (10:23 AM) You know what NERSC have that we don't? Elena Korolkova: (10:23 AM) Thank you very much, Wahid. Ewan Mac Mahon: (10:23 AM) A 40GB perfSonar box wahid: (10:23 AM) https://www.nersc.gov/ Matt Doidge: (10:25 AM) Cheers Wahid! raul: (10:26 AM) tHANKS WAHID. wISH YOU THE BEST John Bland: (10:26 AM) Good luck wahid. wahid: (10:26 AM) I'll collect the chats... thanks Ewan Mac Mahon: (10:26 AM) So, who's going to fix the ECDF xrootd? Govind: (10:26 AM) All the best Wahid.. adieu bye wahid: (10:26 AM) well indeed - it will be andy doing everything... Robert Fay: (10:26 AM) Bye Wahid, see you at some conference somewhere probably wahid: (10:26 AM) cheers - not this chep but mabe the next Elena Korolkova: (10:26 AM) Enjoy your new job, you will be missed Ewan Mac Mahon: (10:26 AM) Indeed; do try to come back for a GridPP or something - we're all about the collaborations now. ]
