Hi Wilko, many thanks for advice. With directive oss.check client is redirected to other node and staging of requested file is started. I have some other questions, if you can help me, it will be super. I want to stage a file from HPSS for example with path like: /home/starreco/reco/productionHigh/FullField/P04ik/2004/040/st_physics_ 5040131_raw_2010003.MuDst.root and copy to path /data0 or /data1 or /data2 or /data3 which I've specified with directives: oss.path /data0 dread nomig stage oss.path /data1 dread nomig stage oss.path /data2 dread nomig stage oss.path /data3 dread nomig stage My question is if my thoughts are right and file with HPPS path: /home/starreco/reco/productionHigh/FullField/P04ik/2004/040/st_physics_ 5040131_raw_2010003.MuDst.root will be staged to local path: /data0/home/starreco/reco/productionHigh/FullField/P04ik/2004/040/st_ph ysics_5040131_raw_2010003.MuDst.root i.e that /data0 is path to ve pre-pended to local path. Or is there some other directive, which can help me to do that ? My second question is if I need to have specified oss.mssgwcmd command when I don't plan to migrate any files from local disk to HPSS ? The third question is about oss.cache directive. Can I have the location of cache in the same directory as I have the files to export ? For example, I have all files in directories: /data0, /data1, /data2 or /data3 (i export with directive xrootd.export) and can I have a oss.cache /data*. My fourth problem is with oss.path again, I've specified this: oss.path /data0 dread nomig stage oss.path /data1 dread nomig stage oss.path /data2 dread nomig stage oss.path /data3 dread nomig stage but in log file is this: oss.path /data3 r/o check dread mig nomkeep nomlock nommap norcreate stage oss.path /data2 r/o check dread mig nomkeep nomlock nommap norcreate stage oss.path /data1 r/o check dread mig nomkeep nomlock nommap norcreate stage oss.path /data0 r/o check dread mig nomkeep nomlock nommap norcreate stage as you can see with mig directive and in addation is here a line: oss.path / r/o check dread mig nomkeep nomlock nommap norcreate stage Is this correct ? Becaouse I dont want to stage any files to path /. (Or is needed due to that / is parent directory ?)
