Thin provisioning when setting up a storage pool
How does (or does) thin provisioning affect the number of physical disks needed to create a single volume with parity redundancy when creating a storage pool? For example, if I need to create a volume with 750 GB of usable space using 200 GB drives, would I still need to use 5 physical drives or would the thin provisioning allow me to use fewer? Thank you

Excellent!! Thank you very much!
I guess you worked out the benefit of letting the OS see more space than there is, it saves having to grow the filesystem after you add more storage. You do have to be careful of filling up the filesystem and then emptying it though because most thin provisioning doesn't realise that space is now free since only the master file table entries are deleted, and be careful of defragmenting as that can have a similar effect.
