Hello Andy, About my writing problem... I got confused and probably got you confused too but I don't want (and need) this machine to be managed by the redirector. I had however forgotten to comment the odc.manager option. == My config file is then the following (I believe it is a config file problem): # dataserver.cf # oss.alloc * * 80 oss.fdlimit * max oss.localroot /home/xrootd/disk/kanga/EventStore/ #oss.path /home/xrootd/disk/kanga/EventStore/ writable xrd.protocol xrootd * xrootd.export /prod xrootd.export /store xrootd.fslib /home/xrootd/software/current/lib/libXrdOfs.so odc.trace redirect olb.trace all oss.trace all xrd.trace all xrootd.trace all == The error message I get with xrdcp is: Error accessing path/file for root://f01-001-124:1094//prod/dummy.root PS: I can actually read the file if I xrdcp the other way around so the path is accessible for read. According to the documentation the default is write allowed (except if I use oss.readonly). The unix directory rights also allow xrootd to write there. == And in the (verbose) log file is: 050331 01:51:45 15028 Exporting /store 050331 01:51:45 15028 Exporting /prod 050331 01:51:45 15028 XRootd protocol version 2.2.0 build 20040907-0403 successfully loaded. 050331 01:51:45 15028 xrd@f01-001-124:1094 initialization completed. 050331 01:51:45 15028 XrdMain: thread 10251 assigned to user handler 050331 01:52:14 15042 XrdNet: Accepted tcp connection from l01-001-122.gridka.de 050331 01:52:14 15042 ?:[log in to unmask] XrdUser: connection accepted 050331 01:52:14 15035 XrdSched: new worker; tid=11276; num=2 050331 01:52:14 15035 XrdSched: running [log in to unmask] inq=0 050331 01:52:14 15035 XrdProtocol: matched protocol xrootd 050331 01:52:14 15035 ?:[log in to unmask] XrdPoll: FD 13 attached to poller 0; num=1 050331 01:52:14 15035 ?:[log in to unmask] XrootdProtocol: 0000 req=3007 dlen=0 050331 01:52:14 15035 xrootd.12395:[log in to unmask] XrootdResponse: 0000 sending OK 050331 01:52:14 15035 XrootdXeq: User logged in as xrootd.12395:[log in to unmask] 050331 01:52:14 15035 xrootd.12395:[log in to unmask] XrootdProtocol: 0000 req=3010 dlen=16 050331 01:52:14 15035 ofs_open: xrootd.12395:[log in to unmask] Unable to create /prod/dummy.root; No such file or directory 050331 01:52:14 15035 xrootd.12395:[log in to unmask] XrootdResponse: 0000 sending err 3011: Unable to create /prod/dummy.root; No such file or directory 050331 01:52:14 15035 xrootd.12395:[log in to unmask] XrdPoll: sending poller 0 detach for link 13 050331 01:52:14 15036 XrdPoll: Poller 0 detached fd 13 entry 1 now at 1 050331 01:52:14 15035 xrootd.12395:[log in to unmask] XrdPoll: FD 13 detached from poller 0; num=0 050331 01:52:14 15035 XrdLink: xrootd.12395:[log in to unmask] disconnected after 0:00:00 -- Gregory On Tue, 29 Mar 2005, abh wrote: >> 050329 19:08:51 6914 odc_Open: Unable to connect socket >> /tmp/.olb/olbd.admin; connection refused > Is teh log truncated or did this connection succeed? > > >> bash-2.05a$ cat config/dataserver.cf >> odc.manager babar2 3121 > Probably doesn't make a difference but one should expand this out completely > with the domain name. > >> #olb.subscribe babar2 3121 > Same thing about expansion.
