I also have checked the permissions on that directory and they seem OK:

As all the processes on the access node are running as www:

The only strange thing, and I am not sure if relevant or not, the directory is trying to create is 5282125afdd416duiuclibrary1, which has the name of our old library server, that is uiuclibrary1 where we copied the data from?  However, our new library server is uiuclibrary12, to which the above access node is trying to connect.

Thanks,

Maged

While selecting a role in a course results in that error on the access servers, selecting an author space works just fine.

Hi All,

I have configured a test cluster, one standalone library and 2 access nodes.  I can work fine from the library, however when I work on the access nodes I get an error when I attempt to view a course:

Map not loaded: The file /home/httpd/html/userfiles/uiuc/2m286089f12d4520auiucaccess1/default.sequence does not exist.

In lonnet.log, I found:
        Fri Dec 19 15:02:38 2014 (1664): Userfile repcopy failed for uploaded/uiuc/2m286089f12d4520auiucaccess1/default.sequence

Below is a directory listing:

/home/httpd/html/userfiles# du -a
4       ./uiuc/5282125afdd416duiuclibrary1
4       ./uiuc/2m286089f12d4520auiucaccess1
4       ./uiuc/1H194910598fe5263uiucaccess2
4       ./uiuc/2u206861b7c7f547cuiuclibrary12
20      ./uiuc
24      .

So the default.sequence does not get created for some reason.

Thanks in advance for all your help.

Maged
