This caused a lot of problems and a solution satisfying also CMS was only possible, by using an undocumented (because probably based on a faulty implementation) possibility in the =/opt/d-cache/etc/LinkGroupAuthorization.conf= file. <pre> LinkGroup cms-linkGroup /cms/Role=* cmssgm/Role=* cmsprd/Role=* cms001/Role=* </pre> In the afternoon of Feb 20th the dCache was functional again and we had successful transfers. For the first time I also was able to observe many successful transfers from ASGC. The total rate was the highest I had seen up to this point. <img src="%ATTACHURLPATH%/fileservers-nw-report-20080221-0957-day.gif" alt="fileservers-nw-report-20080221-0957-day.gif" width='397' height='154' /> <pre> SITE STATISTICS: ================== first entry: 2008-02-21 02:08:16 last entry: 2008-02-21 06:26:34 site: T1_ASGC_Buffer (OK: 180 Err: 0 Exp/Canceled: 122) succ. rate: 100.0 % total: 505.1 GB site: T1_FNAL_Buffer (OK: 39 Err: 39 Exp/Canceled: 4) succ. rate: 50.0 % total: 107.0 GB site: T1_FZK_Buffer (OK: 158 Err: 12 Exp/Canceled: 46) succ. rate: 92.9 % total: 390.1 GB site: T1_IN2P3_Buffer (OK: 69 Err: 72 Exp/Canceled: 6) succ. rate: 48.9 % total: 170.4 GB site: T1_PIC_Buffer (OK: 15 Err: 0 Exp/Canceled: 0) succ. rate: 100.0 % total: 15.5 GB site: T1_RAL_Buffer (OK: 119 Err: 20 Exp/Canceled: 0) succ. rate: 85.6 % total: 331.1 GB TOTAL SUMMARY: ================== first entry: 2008-02-21 02:08:16 last entry: 2008-02-21 06:26:34 total transferred: 1414.9 GB in 4.3 hours avg. total rate: 93.5 MB/s = 747.9 Mb/s = 7888.1 GB/day </pre> Took a look a few moments later on the errors from IN2P3 and FNAL: <pre> *** ERRORS from T1_IN2P3_Buffer:*** 73 Failed SOURCE error during PREPARATION phase: [REQUEST_TIMEOUT] failed to prepare source file in 180 seconds *** ERRORS from T1_FNAL_Buffer:*** 46 transfer timed out after 10845 seconds with signal 9 4 Canceled Job canceled 1 Canceled TRANSFER error during TRANSFER phase: [REQUEST_TIMEOUT] failed to complete srmcopy transfer request in 3600 seconds </pre> %ICON{arrowleft}% Go to [[CMSSiteLog9][previous page]] / [[CMSSiteLog11][next page]] of CMS site log %M% -- Main.DerekFeichtinger - 21 Feb 2008
