Hello, Here is a summary of the xrootd issues still open at GridKa: 1) Writing ========== (I was previously using the -d2 option but it looks like it doesn't exist anymore.) Writing fails (maybe a mistake I did in the config file): [xrootd@babar2 ~/bin]$ setenv XRDPATH /home/xrootd/software/20050328-0656 [xrootd@babar2 ~/bin]$ setenv LD_LIBRARY_PATH $XRDPATH/lib/ [xrootd@babar2 ~/bin]$ $XRDPATH/bin/xrdcp ~/bin/dummy.root root://f01-001-124.gridka.de:1094/prod/dummy.root Error accessing path/file for root://f01-001-124.gridka.de:1094/prod/dummy.root bash-2.05a$ tail xrd.log 050329 19:08:41 6903 XRootd protocol version 2.2.0 build 20040907-0403 successfully loaded. 050329 19:08:41 6903 xrd@f01-001-124:1094 initialization completed. 050329 19:08:46 6910 XrootdXeq: User logged in as xrootd.18420:[log in to unmask] 050329 19:08:46 6910 XrdLink: xrootd.18420:[log in to unmask] disconnected after 0:00:00 050329 19:08:51 6914 odc_Open: Unable to connect socket /tmp/.olb/olbd.admin; connection refused bash-2.05a$ ls -la /tmp/.olb/ total 8 drwx------ 2 xrootd wheel 4096 Mar 29 19:08 . drwxrwxrwt 7 root root 4096 Mar 29 19:08 .. srwx------ 1 xrootd wheel 0 Mar 29 19:08 olbd.admin bash-2.05a$ cat config/dataserver.cf # The Open Distributed Cache Section # odc.manager babar2 3121 # The Open Load Balancer Section # olb.allow host f01-*.gridka.de olb.allow host l01-001-122.gridka.de olb.path r /store olb.path w /prod olb.port 3121 olb.sched cpu 100 #olb.subscribe babar2 3121 olb.wait # The Open File System Section # ofs.redirect remote if l01-001-122.gridka.de ofs.redirect target # The Open Storage System Section (cache & localroot are used by olb) # oss.alloc * * 80 oss.fdlimit * max oss.localroot /home/xrootd/disk/kanga/EventStore/ # The XRD Section # xrd.protocol xrootd * # The XROOTD Section # xrootd.export /prod xrootd.export /store xrootd.fslib /home/xrootd/software/current/lib/libXrdOfs.so # Switch on debugging output # odc.trace redirect #olb.trace all #oss.trace all #xrd.trace all #xrootd.trace all 2) DNS in recent releases ========================= It still crashes but some tests from today morning seems to have solved one server... we'll try tomorrow to make the same change on the others and try to upgrade to the latest version. 3) Exporting multiple directories on GPFS ========================================= I have two servers (maybe only one in the future) and 3 directories to export. I would be very happy if someone had an example on how to use mps to export these. 4) RH8 ====== This is not an issue but I just noticed that one of the NAS box is actually not RH 7.3 but RH 8 so I am compiling myself there. No problem. 5) Other ======== When all that is fixed, I'd like to learn how to use the monitoring in the recent releases. Is it documented somewhere (I just found the CERN presentation of Jacek)?
