xrootd news

dCache news

  • SRM overwrite for dCache at SARA: dCache provides the feature, but Ron has to decide whether or not to enable it. dCache people are currently documenting on how overwrite works in dCache with respect to the tape backend. We expect this to be available within days.

StoRM news

  • Checksum and recommended versions: for SL5 the only version is 1.6.2. For SL4 checksum support is available since 1.5.* The checksum is calculated in two ways that can coexist:
    • via GridFTP on the fly
    • via che Checksummer service (on demand)
The checksum is returned whenever it is defined as a file attribute and it will be calculated by either of the above options.

FTS news

DPM news

LFC news

  • LFC 1.8.0-1 for gLite 3.1: waiting for rebuild of the meta package with the correct VOMS libraries (1.9.10-14)
