The best part about zfs is that oracle or should I say Sun has kept the commands for it pretty easy to understand and remember. To create a file system fs1 in an existing zfs pool geekpool:. Now by default when you create a filesystem into a pool, it can take up all the space in the pool.
So too limit the usage of file system we define reservation and quota. Let us consider an example to understand quota and reservation. We also create a new file system fs2 without any quota and reservation.
So now for fs1 MB is reserved out of 1GB pool size , which no other file system can have it. It can also take upto MB quota out of the pool , but if its is free. On ther other hand when you do a zfs list , you would be able to see the available space for the file system equal to the quota defined for it if space not occupied by other file systems and not the reservation as expected. If you want to change the mount point :. You may also change some other important attributes like compression, sharenfs etc..
Also we can specify attributes while creating the file system itself. With over seven million downloads, FreeNAS has put ZFS onto more systems than any other product or project to date and is used everywhere from homes to enterprises.
FreeNAS uses ZFS because it is an enterprise-ready open source file system and volume manager with unprecedented flexibility and an uncompromising commitment to data integrity. ZFS is a truly next-generation file system that eliminates most, if not all of the shortcomings found in legacy file systems and hardware RAID devices. Once you go ZFS, you will never want to go back. ZFS helps you avoid most storage planning mistakes by pooling together the blocks provided by all of your disks and allowing you to divide the available space into highly-configurable file systems.
Not only that but you can add storage to a pool by adding another drive. ZFS will handle partitioning and formatting. Copy-on-write is another interesting and cool features. On most files system, when data is overwritten, it is lost forever. On ZFS, the new information is written to a different block. Once the write is complete, the file systems metadata is updated to point to the new info. This ensures that if the system crashes or something else happens while the write is taking place, the old data will be preserved.
It also means that the system does not need to run fsck after a system crash. Copy-on-write leads into another ZFS feature: snapshots. ZFS uses snapshots to track changes in the file system. No additional space is used.
As new data is written to the live file system, new blocks are allocated to store this data. So, snapshots are mainly designed to track changes to files, but not the addition and creation of files. Snapshots can be mounted as read-only to recover a past version of a file. It is also possible to rollback the live system to a previous snapshot. All changes made since the snapshot will be lost.
Whenever new data is written to ZFS, it creates a checksum for that data. When that data is read, the checksum is verified. And make sure the VM doesn't use unsafe caching. You can attach ZFS filesystems to Windows with software alternatives that are available to Windows that enable read-write access, not just through VM solutions. You may notice this question is that old, as is the answer.

I'm all over it like hyenas on a downed water buffalo. I was just about to suggest this. The link to Dokan is broken, and from the name alone I'm not sure what's being referred to a lot of different things come up when you search it on Google.
Nevermind, I found it, see suggested edits. I don't suppose there's a precompiled version of zfs-win available anywhere? There's a native ZFS implementation for Windows 10 only?

Oracle's newer zpool versions aren't compatible, of course, but the only feature that seems to be a big issue there is encryption, because the OZFS feature-flag implementation has allowed most features to be replicated without increasing the zpool version.
