Hi, Mihai is trying to setup a small Pss machine that also works as a cache. For reading it seems to work fine, yet it stubbornly refuses to write files with this error: > 180301 17:27:38 13788 XrdFileCache_Manager: debug Cache::Attach() root:[log in to unmask]:1094//eos/xdc/testing/hello.txt?&oss.asize=14&oss.lcl=1 location: <deferred open> > 180301 17:27:38 13788 root.3008:20@xdc-test-fst1 ofs_fstat: fn=/eos/xdc/testing/hello.txt > 180301 17:27:38 13788 root.3008:20@xdc-test-fst1 XrootdResponse: 0100 sending 46 data bytes; status=0 > 180301 17:27:38 13788 root.3008:20@xdc-test-fst1 XrootdProtocol: 0100 req=write dlen=14 > 180301 17:27:38 13788 root.3008:20@xdc-test-fst1 XrootdProtocol: 0100 fh=0 write 14@0 > 180301 17:27:38 13788 root.3008:20@xdc-test-fst1 ofs_write: 14@0 fn=/eos/xdc/testing/hello.txt > 180301 17:27:38 13788 ofs_write: root.3008:20@xdc-test-fst1 Unable to write /eos/xdc/testing/hello.txt; operation not supported > 180301 17:27:38 13788 root.3008:20@xdc-test-fst1 XrootdProtocol: 0100 discarding 0 bytes > 180301 17:27:38 13788 root.3008:20@xdc-test-fst1 XrootdResponse: 0100 sending err 3005: Unable to write /eos/xdc/testing/hello.txt; operation not supported > 180301 17:27:38 13788 root.3008:20@xdc-test-fst1 XrootdProtocol: 0100 req=close dlen=0 > 180301 17:27:38 13788 root.3008:20@xdc-test-fst1 ofs_close: use=1 fn=/eos/xdc/testing/hello.txt If we remove the directive pss.cachelib then writes work instead. Can anyone give us a clue please ?
