Yes, my mistake was probably that I have included data deduplication to see how it works, but not turned it off at the right time . In this case, the machine memory of 4 GB ....
async_destroy - too enabled.
That is the conclusion I have deduplication disabled .
How to import a pool of read-only ?
Thank you for your response .
