Thin Provisioning in ZFS

Ah, Ben understands and did a great demonstration of thin provisioning (also read Dave’s Blog) with ZFS using sparse volumes (zvols).


The ability to thin provision storage is a very “enterprise” feature that one can know get from free when using ZFS+Opensolaris.

When combined with ethernet-based storage networks (iSCSI), it’s unstoppable.

Ben’s also a Joyeur now.

Welcome to the Family, Ben.

  1. I can understand overcommitting storage in a filesystem; writes will just return -ENOSPC when the fs is full. But when the pool backing your sparse zvol fills up, what happens?
