2x Nodes NW 6.5 SP6, Shared SCSI (HP MSA500)

We have the following issue: When the node is idle and not much work to
do, the migration from node1 to node2 goes quiet fast, but when there is
one copy job from a workstation to a (vol) ressource, the migration
of theressource takes about 5 minutes - of course, the client will
report a timeout and stops the copy process.

Ah, and another question is, how many trustees should be on a clustered
volume? how much fdoes this influence the migration/failover process?

Thanks for your input
