Short entry on the copy manager

by admin — posted at 2006-05-05 11:03 last modified 2006-10-06 15:47

To drain a pool Pool1 to pool Pool2, do the following:

Startup the copy manager on thpc-1: /opt/d-cache/jobs/copy start
Login to the dCache admin interface
cd Pool1
p2p set max active 40
..
cd Pool2
pp set max active 40
..
cd copy0
copy Pool1 Pool2 -max=40 -precious
info

Watch the network traffic in Ganglia, and periodically check the progress through dCache with the "info" command. This should net around 1 MB / transfer. In our case, this would be about 40 MB/s.
