Do remember Adv_File supports multiple write but a single read operation.
So, if you operate a staging (disk to tape) of the device,
you cannot recover from.
To stop the staging, you have to kill the corresponding nsrstage process.
To be more accurate, the RO portion of the ADV_FILE device only supports
one clone or one stage operation at once.
If only recoveries are occurring, there are no limits to the number of
concurrent recoveries.
Right -- the old a read is not always a read. And why can't there be recoveries and clones
running at the same time? Because a stage operation is really a clone operation followed by
the deletion of the original -- and NetWorker can't tell if a clone operation is really a clone
or just the first half of a stage. It's logical -- infuriating, but logical.
Bis Spater!
