First tests were for transfers from FZK to PSI: Throughput is quite good. We can fill the 1 Gb/s link if we want. But there is a particular SRM error state failing lots of the transfers. Seems at first sight source related: <pre> Error message statistics per site: =================================== *** ERRORS from T1_DE_FZK_Buffer:*** 294 copy of [srm-URL] into [srm-URL] failed, status = SRM_FAILURE explanation=FAILED: at [date] state Failed : retrieval of "from" TURL failed with error java.lang.ArrayIndexOutOfBoundsException 258 copy of [srm-URL] into [srm-URL] failed, status = SRM_FAILURE explanation=FAILED: at [date] state Failed : retrieval of "from" TURL failed with error java.lang.ArrayIndexOutOfBoundsException: 4 219 copy of [srm-URL] into [srm-URL] failed, status = SRM_FAILURE explanation=FAILED: at [date] state Failed : retrieval of "from" TURL failed with error java.lang.ArrayIndexOutOfBoundsException: 3 126 copy of [srm-URL] into [srm-URL] failed, status = SRM_FAILURE explanation=FAILED: at [date] state Failed : retrieval of "from" TURL failed with error java.lang.ArrayIndexOutOfBoundsException: 2 36 copy of [srm-URL] into [srm-URL] failed, status = SRM_FAILURE explanation=FAILED: at [date] state Failed : retrieval of "from" TURL failed with error java.lang.ArrayIndexOutOfBoundsException: 1 9 copy did not complete or status unknown 5 no detail - validate failed: [unknown reason - inspect log] SITE STATISTICS: ================== first entry: 2008-09-24 12:27:50 last entry: 2008-09-25 12:26:45 T1_DE_FZK_Buffer (OK: 1320 Err: 947 Exp: 0 Canc: 0 Lost: 0) succ.: 58.2 % total: 3260.3 GB (37.8 MB/s) </pre> Impact of this test on total PSI traffic (week view): <br><img src="%ATTACHURLPATH%/PSI-traffic-week-20080925.png" alt="PSI-traffic-week-20080925.png" width='591' height='155' /> Server throughput (2 fileservers used) over last day: <br><img src="%ATTACHURLPATH%/PSI-traffic-servers-20080925.png" alt="PSI-traffic-servers-20080925.png" width='397' height='182' /> ---++ Error Mode: retrieval of "from" TURL failed I found this page of Nicolo Magnini, which states that the respective file is not yet available on the disk server (possibly not yet staged in). https://twiki.cern.ch/twiki/bin/view/CMS/SAMLocalSRMv2 My own tests with copying from T2_CH_CSCS to T3_CH_PSI show that this seems to be an error happening if the source file does not exist in pnfs. ---++ Transfers from CSCS At first I got the following errors from the logs: <pre> *** ERRORS from T2_CH_CSCS:*** 23 copy did not complete or status unknown </pre> Some closer manual investigation showed, that the TFC rule of CSCS for the generated LoadTest filename did not yield an existing file. However, the extracted error message is almost useless for diagnosing this condition. Correcting the rule for the new CMS site names led to successful copies. -- Main.DerekFeichtinger - 25 Sep 2008 ---------------- %ICON{arrowleft}% Go to [[CMSTier3LogXX][next page]] of Tier3 site log %M%
