Emmanuel: I am answering you because Elaine is sick today.
Which version of the operating system are you using? Are you using the 2.8.6 tarball from our website or have you downloaded a different version from our subversion repository? To turn on debugging for the client, assuming you have the kernel module installed, issue the following command: cat /proc/sys/pvfs2/debug-help this produces a list of keywords that can be used to turn on debugging for either the kernel or the client process. You will see two lists, one for the client and one for the kernel. echo "keyword,keyword..." > /proc/sys/pvfs2/client-debug this command will turn on debugging in the client process for the code identified by those keywords. The output will go to the client's log file, typically /tmp/pvfs2-client.log. echo "keyword,keyword..." > /proc/sys/pvfs2/kernel-debug this command will turn on debugging for the kernel module. the output goes into /var/log/messages.
