Hi Henry
Thanks for the tip, this is probably part of the explanation as to why
the rf* commands are not working from off site, but I don't think it
explains the gridftp problems, because here rfio is only being used
internally by DPM:
Remote globus-url-copy ------------------------> DPM gridftp server
|
DPM rfio server
|
disk
I begin to wonder if rfio's really been tested properly for these 64bit
filesystems? Alex, I wonder if you could add a small filesystem (<2TB)
and remove the large one. That might let us know if its the large
filesystem which is causing the trouble.
Cheers
Graeme
