That is one problem with virtual volumes.  The client (server 1) understands
the data in a virtual volume that is being held by another server.  The
server (server 2 - holder of the virtual volume) has a container file and
does not understand what is in it.  So to reclaim, the data must flow back
to server 1 and then back to server two for storage.  There is no lock
condition because server 2 does not do any reclaim on the virtual volumes it
holds.  It can be doing reclaim on its virtual volumes that reside on server
1.  Note that this is 4 times the traffic - from server 2 to server 1 and
back for server 1 reclaim - from server 1 to server 2 and back for server
two reclaim.

Well that is probably confusing enough.
