That last migration process is probably working on the data for a
single nodename, where there can be no more than one migration process
for one nodename.

It may be that there is still a lot of new data entering that disk
pool such that migration is still going on; or, the tape/drive has
issues which is making writing to it difficult and prolonged.  Being
write-shareable, disk pools involve a lot of locking, which adds
overhead, as does caching, which can further prolong runtimes.
