Hi,
Now that I have an libXrdPosixPreload.so to use, I am running into
problems getting this to work. I am trying to set it up to support a
gridftp server but I thought I would first start with a presumably
simpler case. I just want to use "ls" against a file. The README file
for XrdPosix implies that this should work.
I have a file available in the name space that can be copied back to the
client machine, via our redirector:
[mcguigan@gk01 ~]$ /opt/xrootd/bin/xrdcp
root://xrdb.local:1094//xrd/test1/100mb /tmp/wood
[xrootd] Total 95.37 MB |====================| 100.00 % [115.2 MB/s]
I created the following xrdrun.sh file:
#!/bin/sh
export XROOTD_VMP='xrd.local:1094:/xroot/=/xrd/'
export LD_LIBRARY_PATH=/opt/xrootd/lib/
export LD_DEBUG=libs
export LD_PRELOAD=/opt/xrootd/lib/libXrdPosixPreload.so
export XRDPOSIX_DEBUG=3
$*
Shouldn't this allow me to do:
./xrdrun.sh ls /xroot/test1/100mb
./xrdrun.sh ls root://xrdb.local:1094//xrd/test1/100mb
I receive the message "No such file or directory error" from the ls.
With the LD_DEBUG statement I can see that the pre-load library is being
loaded and initialized just prior to ls being loaded. Also, if I
malform the VMP environment varialble, I will get an Invalid map message
from XrdPosix. I don't get any information by setting XRDPOSIX_DEBUG.
Should this work?
How can I debug this? I tried rebuilding the XrdPosix libraries with a
couple of very simple output statements in XrdPosixXrootPath::URL but I
get seg faults when I try to use them.
I am working on SL4.5 X86_64.
Any advice is greatly appreciated.
Patrick
