Does anyone know what the overhead of a zfs snapshot is? I'm not talking about the data, I'm talking about whatever space zfs needs to allocate internally for housekeeping.
A quick estimate indicates something around 2M of overhead. (I've just deleted ~35k snapshots on a system, each taking no space. I was a little surprised - although pleased - to get ~70G of space back in the pool.) -- -Peter Tribble http://www.petertribble.co.uk/ - http://ptribble.blogspot.com/
