Xrootd333Upgrade

Introduction

Xrootd release 3.3.3 from xrootd.org contains a set of RPMs different from previous Xrootd releases. Though the configuration files (/etc/xrootd/xrootd-clustered.cfg and /etc/sysconfig/xrootd), init scripts (/etc/init.d/{xrootd,cmsd)) and operation directories (/var/{log,run,spool}/xrootd) remain unchanged.

Release 3.3.3 contain a number of new features developed for FAX. FAX sites are encouraged to upgrade to this release. After YUM update, running xrootd may crash, new xrootd instance may not start due to the above changes. If your site encount these problems, do the following:

  • Append a line "exclude=xrootd-server" to the xrootd.org YUM repo file (remember to remove this line if you want to test releases older than 3.3.3)
  • Make sure /etc/xrootd/xrootd-clustered.cfg and /etc/sysconfig/xrootd are not changed after YUM update.
  • as root, run "service xrootd setup". You only need to do this once
  • start xrootd and cmsd services

The following RPMs are needed:

xrootd
xrootd-libs
xrootd-devel
xrootd-client
xrootd-client-libs
xrootd-client-devel
xrootd-server-libs
xrotod-server-devel
json-c (from EPEL)
curl (from RHEL or SLC)
vomsxrd (available at /afs/cern.ch/work/g/ganis/public/vomsxrd/RPMS)

    • Add "all.sitename SITENAME". SITENAME can be found under "ATLAS Name" column at https://atlas-agis.cern.ch:2821/agis/atlassite/table_view/.
    • f-stream related configuration change: change whatever you currently have in your xrootd.monitor to: "xrootd.monitor all auth flush 30s window 5s rbuff 4k fstat 60 lfn ops xfr 5 dest redir files info user atl-prod05.slac.stanford.edu:9930"
  • Add the following to /etc/sysconfig/xrootd (SL6 only)
    • export MALLOC_ARENA_MAX=4 (to control memory growth)
