No – it means I need to wear my glasses!
I was looking at the disk storage controller statistics and saw references to pinned storage. I naturally thought this was a reference to the Monty Python dead parrot sketch where the Norwegian Blue was “pining for the Fiords”.
Ive often wondered what Pinned storage was. I found “Pinned data cannot be removed from the cache by the storage machine because of a hardware failure”. I think that if the amount of pinned storage is greater than zero then phone someone.
There are other fields “Unavailable storage”.
These are examples of providing data – but no information. You need to know that if these fields are non zero, this is a problem and you need to do something about it – just displaying a number has little value. I would have hoped that that documentation would have said, in big bold letters: If these numbers are not zero then take action!
