Debugging Overflow Read-Access errors from a crabserver perspective
Logical Procedure
login as root into the relevant crabserver
figure out via condor history commands which jobs failed with Exit code 84
find the username of the people who those jobs belong to
use the
UCSD GUMS
mapping to figure out the DNs
cd to the crabserver spool directory
use ls and grep to figure out which directory belongs to the user you are looking for.
the first few characters are the hn name of the person in the directory name. So guessing shouldn't be too hard.
inside the correct directory you can find arguments.xml, fjr, and the stdout/err inside the appropriate outfile_XXX.tgz file.
Details you need for doing this
crabservers are:
glidein-2 with /var/gftp_cache/CSstoragePath as spool directory
submit-2 with /crabprod/CSstoragePath as spool directory
to find the jobs that failed with read access error "grep 8020 *fjr*"
to see what file the job failed to open do a less on the corresponding fjr. It will say so near the top.
to verify yourself that this file can't be opened, try using xrootd with this users proxy. The proxy is in the directory as well.
ask somebody else how to setp up root such that you can use xrootd client on the crabserver while logged in as root.
/code/osgcode is probably mounted, and you can find the
CMSSW
release directory from there if you know what you are doing, maybe.
