Dear XRoot folks, I am seeing some odd behavior with a meta manager. The configuration is such that a simple proxy server is used to connect to a meta manager. I am testing the existence of a directory (which I know exists) on a data server and local redirector that are dual NIC's and are only a private network. All of the traffic between the local redirector and data server is through the private network only. I am testing for the directory through the meta manager from two different machines. 1) on the same network as the local redirector and one offsite. Here is my testing squence: 1) From Machine offsite (atl010.phy.duke.edu) [benjamin@atl010 ~]$ xrd grd.usatlas.org:1094 locateall /atlas/ANLASC_TEST/mc10_7TeV.105802.JF17_pythia_jet_filter.merge.NTUP_SUSY.e577_s933_s946_r1831_r2040_p428_tid281325_00 Not connected to any server. 2) shortly afterwards from machine on the same network as the local redirector and data server (onsite) (ascint0y.hep.anl.gov) [dbenjamin@ascint0y ~]$ date Wed Aug 31 07:37:40 CDT 2011 [dbenjamin@ascint0y ~]$ xrd glrd.usatlas.org:1094 locateall /atlas/ANLASC_TEST/mc10_7TeV.105802.JF17_pythia_jet_filter.merge.NTUP_SUSY.e577_s933_s946_r1831_r2040_p428_tid281325_00 ------------- Location #1 InfoType: kXrdcLocDataServer CanWrite: false Location: '130.202.173.4:1094' ------------- Location #2 InfoType: kXrdcLocDataServer CanWrite: false Location: '130.202.173.42:41094' 3) Immediately aftwards repeat the query on the offsite machine (note the machines are in two different time zones) [benjamin@atl010 ~]$ date Wed Aug 31 08:38:04 EDT 2011 [benjamin@atl010 ~]$ xrd glrd.usatlas.org:1094 locateall /atlas/ANLASC_TEST/mc10_7TeV.105802.JF17_pythia_jet_filter.merge.NTUP_SUSY.e577_s933_s946_r1831_r2040_p428_tid281325_00 ------------- Location #1 InfoType: kXrdcLocDataServer CanWrite: false Location: '130.202.173.4:1094' ------------- Location #2 InfoType: kXrdcLocDataServer CanWrite: false Location: '130.202.173.42:41094' Both machines (atl010.phy.duke.edu and ascint0y.phy.duke.edu) have the same time to within 2 seconds of each other. (except for the 1 hour time zone difference) Any Idea why the first time the remote machine did not get any answer back? Finally, how long does it talk for a meta manager to drop a data server (or proxy) from its list automatically. (The second proxy (130.202.173.42:41094) was turned off ~6 hours ago. Thanks, Doug Benjamin
