This is a long shot, but...

You're writing to a virtual volume, so you've got a device class that
uses a device type of "server". Check the mountlimit on that device
class and compare it to the mountlimit of the device class used by the
storage pool on the target server that is written to during the above
operation. They should be the same number.
