We've switched to the latest production version on one of our dataservers, but now the olb on the dataserver complains that there are no writable file systems. 070626 15:40:54 001 [log in to unmask] phase 1 server initialization suceeded. 070626 15:40:54 001 [log in to unmask] phase 2 server initialization started. 070626 15:40:54 001 olb_Meter: Warning! No writable filesystems found; write access and staging prohibited. 070626 15:40:54 001 [log in to unmask] phase 2 server initialization completed. 070626 15:40:54 001 olbd [log in to unmask]:54571 initialization completed. The config we are using on this sever looks like this: all.manager l01-001-110.gridka.de 3121 all.role manager if l01-001-110.gridka.de all.role server if f01*.gridka.de olb.path r /store olb.path w /prod olb.port 3121 olb.sched cpu 100 oss.alloc * * 80 oss.fdlimit * max oss.localroot /export/gka1900/babar10/kanga/EventStore xrd.protocol xrootd * xrootd.async off xrootd.chksum crc32 /home/xrootd/bin/getCRC32.sh xrootd.export /prod xrootd.export /store xrootd.fslib /home/xrootd/software/gpfs/current/lib/libXrdOfs.so xrootd.monitor all dest files info user babar2:9930 The /prod and /store areas are actually on the same file system: ls -l /export/gka1900/babar10/kanga/EventStore total 64 drwxrwxr-x 5 babaradm babar 32768 Jun 26 14:32 prod drwxrwxr-x 7 babaradm babar 32768 Apr 16 09:56 store The user that is running xrootd belongs to the group 'babar' so we don't think it is a permissions problem.
