Agenda

  • 1 second delay in PnfsManager and 1.9.2 branch
    • Timur: revert the patch. agree that fixing in pnfs is better. Error can be reproduced by hand.

The question is: can we release pnfs? There are other fixes as well, but pnfs not released.

  • Paul: we can build rpm, but there is a risk to introduce a new bug.
  • Gerd: Jon run's a custom build based on trunk + 64 bit patch.
  • Paul: can jon test it?
  • Timur: we can test, Jon will install in July
  • Paul: is there sites will upgrade to pnfs-RC?

  • Tigran: No, there is no test suite for pnfs.
  • Gerd: there is a patch which drops exception
  • Timur: there is other patches as well
  • Gerd: two patches on checksums - pool bug and protection on update

  • SRM not starting,
    • Paul: there is a command dcache-srm. For what ever reason you got ClassNotFoud?....or?....
    • Dmitry: normaly, on a startup you get an exception
    • Timur: we need ping to start SRM in axis, causes an exception, but srm is started.
    • Dmitry: tigran pointed to timing issue, but if it's 100% reproducable, then it's not a timing.
    • Timur: there is an paramert to wait in srm_setup.env: tomcat startup delay - default 10seconds
    • Paul: it's not that long
    • Timur: is there exceptions?
    • Paul: no, even catalina.out is empty. dcache stop srm && dcache start srm does not starts srm.

with manual ping every thing started to work.

  • Timur: kick start procedure does not start Does your host certs are in standart location?
  • Paul: hope so
