Heya Santanu,
I've seen the "connection closed by remote end" type errors before,
when my disk server traffic was accidentially being natted. I've also
had problems caused by a disk server picking up its "internal"
networks name rather then the "external", proper name, so check
`hostname -f` returns what it should. My final suggestion is check
that the server has the correct host certificate in place, I've had
wierdness before where I mixed up the certificates between two pools.
The gridftp logs might have clues in them as I see that gridftp
startup failed.

Hope that helps,
Matt

Hi Wahid,

Already checked the shift.conf and that's fine.
These are in the dpm log:

Hi
Does the head node "trust" the pool server for dpm operations ie is the new
disk server in the line
DPM TRUST
in /etc/shift.conf on the head node
if so is there anything in the dpm logs on the head node

Dear all,

Trying out EMI version of dpm_disk_server and during the configuration, it
fails with these:

If I try to add the file system manually (using dpm-addfs) on the SE,
returns the very same error:

dpm-addfs dpmCam_2007 disk08.hep.phy.cam.ac.uk /dpm_data: Connection closed
by remote end

traceroute works just fine from the SE to disk08:

[root@serv02 /]# traceroute disk08
traceroute to disk08.hep.phy.cam.ac.uk (131.111.66.178), 30 hops max, 46
byte packets
 1  disk08 (131.111.66.178)  1.009 ms  0.085 ms  0.069 ms

I think I saw this problem before but can't remember what was the catch. Any
idea what am I missing?

Cheers,
Santanu
