Thank you, I need clarification on what you mean by badly fragmented data
on tape. We are restoring full drives, so do you mean that a file is on
one tape and the next file is on another? Does reclamation try to any kind
of node consolidation?
I'm going to try the move nodedata.
Thank you.

[ Oh yeah, you could also... ]
If you MOVE NODEDATA for the affected filesystem onto disk, you can do
several things: rule out badly fragmented data on the tapes (if it
takes hours to move data from LT0 to local disk, then you have very
very poor fragmentation characteristics) and then you can do the
restore off the disk, which should rule out backhitch problems.
Once those two sources are cut out, it'll probably be really clear if
the network is in the way.
