It s out

It’s out!

Xrootd bundle vmss_1.8

  • Since today the new version vmss_1.8 of the xrd-installer bundle is available

  • Main items:

    • The ApMon proliferation issue

    • Xrd3cp from Andreas

    • Xrootd base : 20100510-1509

  • Used also in the ALICE CAF


The apmon proliferation

The ApMon proliferation

Xrootd bundle vmss_1.8

  • Under some circumstances the ApMon processes were not detected correctly and were started again and again

    • Result: a lot of them

    • Fixed now, in the ApMon-related scripts

    • Remember to kill them manually before restarting after the upgrade


Xrd3cp

Xrd3cp

Xrootd bundle vmss_1.8

A new plugin was added: xrootd-ftsofs

Third party ‘file push’

The tests at CERN and Legnaro were successful

Several improvements can be foreseen (mainly performance)


Xrootd base

Xrootd base

Xrootd bundle vmss_1.8

  • Like always, a huge number of commits

    • And a very long test phase

  • A few minor bugs in XrdClient

    • Xrdcp is able to detect additional failure modes and act correctly

    • Enhanced fault tolerance (the Legnaro problem)

      • In the case of flaky dataservers going in/out the redirector’s response can be wrong

      • Now the client copes better with that

      • Moreover, they fixed the flaky dataserver (name resolution issues?)
