  21. CheckDpmConsistency • https://twiki.cern.ch/twiki/bin/view/LCG/CheckDpmConsistency • Author: Lana Abadie • The DPM consistency check tool is an admin tool which can be used for the following purposes • behaviour by default: • it allows listing files which are stored in the name server but not physically stored; • it allows listing files which are stored physically and not declared in the DPNS DB; • it allows listing files whose sizes stored in the name server differ from the physical size ATLAS DDM Operations

  22. dpns-cleanup • By Lana Abadie • I tested it when we lost all files at 1 pool node • Uses these main calls: • dpns_listreplicax • dpns_delreplica • dpns_getpath • dpns_unlink • Example: ./dpns-cleanup --dpns_host_name golias100.farm.particle.cz --server se2.farm.particle.cz started at 11:06, finished 14:22 deleted 24414 files.
