Hello Pavel I suspect that this is a problem with the mss configuration. In the dev. version the mss command is ignored if the path is only stage-able and nodread, nocheck, nomig are specified. Do you see in the xrdlog file the line mssgwcmd ignored; no MSS paths present. from the xrootd startup ? If this is the case you could add oss.check to your config which should cause xrootd to use the mssgwcmd command. (oss.dread ot oss.rcreate should also do the trick). But if you specify any of these options xrootd will behave a little bit different from how it is configured now. The problem has been fixed in CVS and will be in the next release.
