Hello, Following several tests we have confirmed onfirmed that "xrdcp -f" definitely deletes a Ceph file; The first attempt to overwrite the file with "xrdcp -f" results in the following error. Run: [ERROR] Server responded with an error: [3007] Unable to open dteam:overwritetest/test1; input/output error Examining the "overwritten" file at the rados level, one sees that it is not just that the striper.size is set to 0, but that all data stripes are gone. Further attempts to overwrite this (deleted) file result in xrdcp hanging and occassionaly issuing the message "Output file alice:... is already opened by 1 writer; open denied". This is probably a bug in the xrootd-ceph plugin for which I opened a git hub issue here https://github.com/xrootd/xrootd-ceph/issues/1 also opened an in issue in the xrootd git repo https://github.com/xrootd/xrootd/issues/1084 How possible is that this is fixed? Many thanks, George ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the XROOTD-L list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=XROOTD-L&A=1
