We started using Virtual Volumes earlier this year for some new branch
locations with no local, long-term storage.
As it works, multiple virtual volumes will get stacked into one "real"
sequential volume.

The problem is that periodically, a reclamation process will require two
volumes that happen to be stacked together.   On the destination side, it
cancels one of the mounts with a  "being preempted by higher priority
operation", then the whole reclamation fails and the first volume is
marked "read-only"

As I write this an idea come to the fore.  Perhaps I should be using the
RECLAIMSTGpool feature.   Does anyone else have this problem?  Is
RECLAIMSTGpool the standard workaround?


Regards,
Shawn
